Ascent of Denali

<h2>CHAPTER V</h2> <h3>THE ULTIMATE HEIGHT</h3> We lay down for a few hours on the night of the 6th June, resolved to rise at three in the morning for our attempt upon the summit of Denali. At supper Walter had made a desperate effort to use some of our ten pounds of flour in the manufacture of “noodles” with which to thicken the stew. We had continued to pack that flour and had made effort after effort to cook it in some eatable way, but without success. The sour dough would not ferment, and we had no baking-powder. Is there any way to cook flour under such circumstances? But he made the noodles too large and did not cook them enough, and they wrought internal havoc upon those who partook of them. Three of the four of us were unwell all night. The digestion is certainly more delicate and more easily disturbed at great altitudes than at the lower levels. While Karstens and Tatum were tossing uneasily in the bedclothes, the writer sat up with a blanket round his [Pg 93]shoulders, crouching over the primus stove, with the thermometer at −21° F. outdoors. Walter alone was at ease, with digestive and somnolent capabilities proof against any invasion. It was, of course, broad daylight all night. At three the company was aroused, and, after partaking of a very light breakfast indeed, we sallied forth into the brilliant, clear morning with not a cloud in the sky. The only packs we carried that day were the instruments and the lunch. The sun was shining, but a keen north wind was blowing and the thermometer stood at −4° F. We were rather a sorry company. Karstens still had internal pains; Tatum and I had severe headaches. Walter was the only one feeling entirely himself, so Walter was put in the lead and in the lead he remained all day. <div class="figcenter"> <ANTIMG src="./images/denali26_sm.jpg" alt="Illustration:" height-obs="400" width-obs="241" /></div> The South Peak from about 18,000 feet. The ridge with two peaks in the background is shaped like a horseshoe, and the highest point on the mountain is on another little ridge just beyond, parallel with the ridge that shows, almost at the middle point between the two peaks. <div class="sidenote">Start to the Summit</div> <div class="sidenote">Cold</div> We took a straight course up the great snow ridge directly south of our camp and then around the peak into which it rises; quickly told but slowly and most laboriously done. It was necessary to make the traverse high up on this peak instead of around its base, so much had its ice and snow been shattered by the earthquake on the lower portions. Once around this peak, there rose before us the horseshoe ridge which carries the ultimate height of Denali, a horseshoe ridge [Pg 94]of snow opening to the east with a low snow peak at either end, the centre of the ridge soaring above both peaks. Above us was nothing visible but snow; the rocks were all beneath, the last rocks standing at about 19,000 feet. Our progress was exceedingly slow. It was bitterly cold; all the morning toes and fingers were without sensation, kick them and beat them as we would. We were all clad in full winter hand and foot gear—more gear than had sufficed at 50° below zero on the Yukon trail. Within the writer’s No. 16 moccasins were three pairs of heavy hand-knitted woollen socks, two pairs of camel’s-hair socks, and a pair of thick felt socks; while underneath them, between them and the iron “creepers,” were the soles cut from a pair of felt shoes. Upon his hands were a pair of the thickest Scotch wool gloves, thrust inside huge lynx-paw mitts lined with Hudson Bay duffle. His moose-hide breeches and shirt, worn all the winter on the trail, were worn throughout this climb; over the shirt was a thick sweater and over all the usual Alaskan “parkee” amply furred around the hood; underneath was a suit of the heaviest Jaeger underwear—yet until nigh noon feet were like lumps of iron and fingers were constantly numb. That north wind was cruelly cold, and there can be [Pg 95] no possible question that cold is felt much more keenly in the thin air of nineteen thousand feet than it is below. But the north wind was really our friend, for nothing but a north wind will drive all vapor from this mountain. Karstens beat his feet so violently and so continually against the hard snow to restore the circulation that two of his toe-nails sloughed off afterward. By eleven o’clock we had been climbing for six hours and were well around the peak, advancing toward the horseshoe ridge, but even then there were grave doubts if we should succeed in reaching it that day, it was so cold. A hint from any member of the party that his feet were actually freezing—a hint expected all along—would have sent us all back. When there is no sensation left in the feet at all it is, however, difficult to be quite sure if they be actually freezing or not—and each one was willing to give the attempt upon the summit the benefit of the doubt. What should we have done with the ordinary leather climbing boots? But once entirely around the peak we were in a measure sheltered from the north wind, and the sun full upon us gave more warmth. It was hereabouts, and not, surely, at the point indicated in the photograph in Mr. Belmore Browne’s book, that the climbing party of last year was driven back [Pg 96]by the blizzard that descended upon them when close to their goal. Not until we had stopped for lunch and had drunk the scalding tea from the thermos bottles, did we all begin to have confidence that this day would see the completion of the ascent. But the writer’s shortness of breath became more and more distressing as he rose. The familiar fits of panting took a more acute form; at such times everything would turn black before his eyes and he would choke and gasp and seem unable to get breath at all. Yet a few moments’ rest restored him completely, to struggle on another twenty or thirty paces and to sink gasping upon the snow again. All were more affected in the breathing than they had been at any time before—it was curious to see every man’s mouth open for breathing—but none of the others in this distressing way. Before the traverse around the peak just mentioned, Walter had noticed the writer’s growing discomfort and had insisted upon assuming the mercurial barometer. The boy’s eager kindness was gladly accepted and the instrument was surrendered. So it did not fall to the writer’s credit to carry the thing to the top as he had wished. <div class="sidenote">Climbing-Irons</div> The climbing grew steeper and steeper; the slope that had looked easy from below now seemed [Pg 97]to shoot straight up. For the most part the climbing-irons gave us sufficient footing, but here and there we came to softer snow, where they would not take sufficient hold and we had to cut steps. The calks in these climbing-irons were about an inch and a quarter long; we wished they had been two inches. The creepers are a great advantage in the matter of speed, but they need long points. They are not so safe as step-cutting, and there is the ever-present danger that unless one is exceedingly careful one will step upon the rope with them and their sharp calks sever some of the strands. They were, however, of great assistance and saved a deal of laborious step-cutting. At last the crest of the ridge was reached and we stood well above the two peaks that mark the ends of the horseshoe.[4] Also it was evident that we were well above the great North Peak across the Grand Basin. [Pg 98]Its crest had been like an index on the snow beside us as we climbed, and we stopped for a few moments when it seemed that we were level with it. We judged it to be about five hundred feet lower than the South Peak. <div class="figcenter"> <ANTIMG src="./images/denali27_sm.jpg" alt="The climbing-irons." height-obs="400" width-obs="261" /></div> The climbing-irons. But still there stretched ahead of us, and perhaps one hundred feet above us, another small ridge with a north and south pair of little haycock summits. This is the real top of Denali. From below, this ultimate ridge merges indistinguishably with the crest of the horseshoe ridge, but it is not a part of it but a culminating ridge beyond it. With keen excitement we pushed on. Walter, who had been in the lead all day, was the first to scramble up; a native Alaskan, he is the first human being to set foot upon the top of Alaska’s great mountain, and he had well earned the lifelong distinction. Karstens and Tatum were hard upon his heels, but the last man on the [Pg 99]rope, in his enthusiasm and excitement somewhat overpassing his narrow wind margin, had almost to be hauled up the last few feet, and fell unconscious for a moment upon the floor of the little snow basin that occupies the top of the mountain. This, then, is the actual summit, a little crater-like snow basin, sixty or sixty-five feet long and twenty to twenty-five feet wide, with a haycock of snow at either end—the south one a little higher than the north. On the southwest this little basin is much corniced, and the whole thing looked as though every severe storm might somewhat change its shape. So soon as wind was recovered we shook hands all round and a brief prayer of thanksgiving to Almighty God was said, that He had granted us our hearts’ desire and brought us safely to the top of His great mountain. <div class="sidenote">The Instrument Readings</div> This prime duty done, we fell at once to our scientific tasks. The instrument-tent was set up, the mercurial barometer, taken out of its leather case and then out of its wooden case, was swung upon its tripod and a rough zero established, and it was left awhile to adjust itself to conditions before a reading was attempted. It was a great gratification to get it to the top uninjured. The boiling-point apparatus was put together and its [Pg 100]candle lighted under the ice which filled its little cistern. The three-inch, three-circle aneroid was read at once at thirteen and two-tenths inches, its mendacious altitude scale confidently pointing at twenty-three thousand three hundred feet. Half an hour later it had dropped to 13.175 inches and had shot us up another one hundred feet into the air. Soon the water was boiling in the little tubes of the boiling-point thermometer and the steam pouring out of the vent. The thread of mercury rose to 174.9° and stayed there. There is something definite and uncompromising about the boiling-point hypsometer; no tapping will make it rise or fall; it reaches its mark unmistakably and does not budge. The reading of the mercurial barometer is a slower and more delicate business. It takes a good light and a good sight to tell when the ivory zero-point is exactly touching the surface of the mercury in the cistern; it takes care and precision to get the vernier exactly level with the top of the column. It was read, some half-hour after it was set up, at 13.617 inches. The alcohol minimum thermometer stood at 7° F. all the while we were on top. Meanwhile, Tatum had been reading a round of angles with the prismatic compass. He could not handle it with sufficient exactness with [Pg 101]his mitts on, and he froze his fingers doing it barehanded. <div class="sidenote">The View</div> The scientific work accomplished, then and not till then did we indulge ourselves in the wonderful prospect that stretched around us. It was a perfectly clear day, the sun shining brightly in the sky, and naught bounded our view save the natural limitations of vision. Immediately before us, in the direction in which we had climbed, lay—nothing: a void, a sheer gulf many thousands of feet deep, and one shrank back instinctively from the little parapet of the snow basin when one had glanced at the awful profundity. Across the gulf, about three thousand feet beneath us and fifteen or twenty miles away, sprang most splendidly into view the great mass of Denali’s Wife, or Mount Foraker, as some white men misname her, filling majestically all the middle distance. It was our first glimpse of her during the whole ascent. Denali’s Wife does not appear at all save from the actual summit of Denali, for she is completely hidden by his South Peak until the moment when his South Peak is surmounted. And never was nobler sight displayed to man than that great, isolated mountain spread out completely, with all its spurs and ridges, its cliffs and its glaciers, lofty and mighty and yet far beneath [Pg 102]us. On that spot one understood why the view of Denali from Lake Minchúmina is the grand view, for the west face drops abruptly down with nothing but that vast void from the top to nigh the bottom of the mountain. Beyond stretched, blue and vague to the southwest, the wide valley of the Kuskokwim, with an end of all mountains. To the north we looked right over the North Peak to the foot-hills below, patched with lakes and lingering snow, glittering with streams. We had hoped to see the junction of the Yukon and Tanana Rivers, one hundred and fifty miles away to the northwest, as we had often and often seen the summit of Denali from that point in the winter, but the haze that almost always qualifies a fine summer day inhibited that stretch of vision. Perhaps the forest-fires we found raging on the Tanana River were already beginning to foul the northern sky. <div class="figcenter"> <ANTIMG src="./images/denali28_sm.jpg" alt="Denali’s Wife from the summit of Denali" height-obs="241" width-obs="400" /></div> Denali’s Wife from the summit of Denali It was, however, to the south and the east that the most marvellous prospect opened before us. What infinite tangle of mountain ranges filled the whole scene, until gray sky, gray mountain, and gray sea merged in the ultimate distance! The near-by peaks and ridges stood out with dazzling distinction, the glaciation, the drainage, the relation of each part to the others all revealed. The [Pg 103]snow-covered tops of the remoter peaks, dwindling and fading, rose to our view as though floating in thin air when their bases were hidden by the haze, and the beautiful crescent curve of the whole Alaskan range exhibited itself from Denali to the sea. To the right hand the glittering, tiny threads of streams draining the mountain range into the Chulitna and Sushitna Rivers, and so to Cook’s Inlet and the Pacific Ocean, spread themselves out; to the left the affluents of the Kantishna and the Nenana drained the range into the Yukon and Bering Sea. Yet the chief impression was not of our connection with the earth so far below, its rivers and its seas, but rather of detachment from it. We seemed alone upon a dead world, as dead as the mountains on the moon. Only once before can the writer remember a similar feeling of being neither in the world <ins class="correction" title="Transcriber's note: original reads 'or'"> nor</ins> of the world, and that was at the bottom of the Grand Cañon of the Colorado, in Arizona, its savage granite walls as dead as this savage peak of ice. <div class="sidenote">The Dark Sky</div> Above us the sky took a blue so deep that none of us had ever gazed upon a midday sky like it before. It was a deep, rich, lustrous, transparent blue, as dark as a Prussian blue, but intensely blue; a hue so strange, so increasingly impressive, [Pg 104]that to one at least it “seemed like special news of God,” as a new poet sings. We first noticed the darkening tint of the upper sky in the Grand Basin, and it deepened as we rose. Tyndall observed and discussed this phenomenon in the Alps, but it seems scarcely to have been mentioned since. It is difficult to describe at all the scene which the top of the mountain presented, and impossible to describe it adequately. One was not occupied with the thought of description but wholly possessed with the breadth and glory of it, with its sheer, amazing immensity and scope. Only once, perhaps, in any lifetime is such vision granted, certainly never before had been vouchsafed to any of us. Not often in the summer-time does Denali completely unveil himself and dismiss the clouds from all the earth beneath. Yet we could not linger, unique though the occasion, dearly bought our privilege; the miserable limitations of the flesh gave us continual warning to depart; we grew colder and still more wretchedly cold. The thermometer stood at 7° in the full sunshine, and the north wind was keener than ever. My fingers were so cold that I would not venture to withdraw them from the mittens to change the film in the camera, and the other men [Pg 105]were in like case; indeed, our hands were by this time so numb as to make it almost impossible to operate a camera at all. A number of photographs had been taken, though not half we should have liked to take, but it is probable that, however many more exposures had been made, they would have been little better than those we got. Our top-of-the-mountain photography was a great disappointment. One thing we learned: exposures at such altitude should be longer than those below, perhaps owing to the darkness of the sky. <div class="figcenter"> <ANTIMG src="./images/denali29_sm.jpg" alt="Robert Tatum raising the Stars and Stripes on the highest point in North America." height-obs="400" width-obs="301" /></div> Robert Tatum raising the Stars and Stripes on the highest point in North America. This photograph was exposed upon a previous exposure. <div class="sidenote">The Stars and Stripes</div> When the mercurial barometer had been read the tent was thrown down and abandoned, the first of the series of abandonments that marked our descent from the mountain. The tent-pole was used for a moment as a flagstaff while Tatum hoisted a little United States flag he had patiently and skilfully constructed in our camps below out of two silk handkerchiefs and the cover of a sewing-bag. Then the pole was put to its permanent use. It had already been carved with a suitable inscription, and now a transverse piece, already prepared and fitted, was lashed securely to it and it was planted on one of the little snow turrets of the summit—the sign of our redemption, high above North America. Only some peaks in the Andes and some peaks in the Himalayas rise above [Pg 106]it in all the world. It was of light, dry birch and, though six feet in length, so slender that we think it may weather many a gale. And Walter thrust it into the snow so firmly at a blow that it could not be withdrawn again. Then we gathered about it and said the Te Deum. <div class="figcenter"> <ANTIMG src="./images/denali30_sm.jpg" alt="The saying of the Te Deum." height-obs="255" width-obs="400" /></div> The saying of the Te Deum. This picture was snapped three times instead of once. Karstens’ fingers were freezing and the bulb-release was broken. Only three figures were in the group. It was 1.30 P. M. when we reached the summit and two minutes past three when we left; yet so quickly had the time flown that we could not believe we had been an hour and a half on top. The journey down was a long, weary grind, the longer and the wearier that we made a détour and went out of our way to seek for Professor Parker’s thermometer, which he had left “in a crack on the west side of the last boulder of the northeast ridge.” That sounds definite enough, yet in fact it is equivocal. “Which is the last boulder?” we disputed as we went down the slope. A long series of rocks almost in line came to an end, with one rock a little below the others, a little out of the line. This egregious boulder would, it seemed to me, naturally be called the last; Karstens thought not—thought the “last boulder” was the last on the ridge. As we learned later, Karstens was right, and since he yielded to me we did not find the thermometer, for, having descended to this isolated rock, we would not climb up again [Pg 107]for fifty thermometers. One’s disappointment is qualified by the knowledge that the thermometer is probably not of adequate scale, Professor Parker’s recollection being that it read only to 60° below zero, F. A lower temperature than this is recorded every winter on the Yukon River. <div class="sidenote">Possible Temperatures</div> A thermometer reading to 100° below zero, left at this spot, would, in my judgment, perhaps yield a lower minimum than has ever yet been authentically recorded on earth, and it is most unfortunate that the opportunity was lost. Yet I did not leave my own alcohol minimum—scaled to 95° below zero, and yielding, by estimation, perhaps ten degrees below the scaling—there, because of the difficulty of giving explicit directions that should lead to its ready recovery, and at the close of such a day of toil as is involved in reaching the summit, men have no stomach for prolonged search. As will be told, it is cached lower down, but at a spot where it cannot be missed. However, for one, the writer was largely unconscious of weariness in that descent. All the way down, my thoughts were occupied with the glorious scene my eyes had gazed upon and should gaze upon never again. In all human probability I would never climb that mountain again; yet if I climbed it a score more times I would Pg 108]never be likely to repeat such vision. Commonly, only for a few hours at a time, never for more than a few days at a time, save in the dead of winter when climbing is out of the question, does Denali completely unveil himself and dismiss the clouds from all the earth beneath him. Not for long, with these lofty colds contiguous, will the vapors of Cook’s Inlet and Prince William Sound and the whole North Pacific Ocean refrain from sweeping upward; their natural trend is hitherward. As the needle turns to the magnet so the clouds find an irresistible attraction in this great mountain mass, and though the inner side of the range be rid of them the sea side is commonly filled to overflowing. <div class="sidenote">The Te Deum</div> Only those who have for long years cherished a great and almost inordinate desire, and have had that desire gratified to the limit of their expectation, can enter into the deep thankfulness and content that filled the heart upon the descent of this mountain. There was no pride of conquest, no trace of that exultation of victory some enjoy upon the first ascent of a lofty peak, no gloating over good fortune that had hoisted us a few hundred feet higher than others who had struggled and been discomfited. Rather was the feeling that a privileged communion with the high places of the earth had been granted; that not [Pg 109]only had we been permitted to lift up eager eyes to these summits, secret and solitary since the world began, but to enter boldly upon them, to take place, as it were, domestically in their hitherto sealed chambers, to inhabit them, and to cast our eyes down from them, seeing all things as they spread out from the windows of heaven itself. Into this strong yet serene emotion, into this reverent elevation of spirit, came with a shock a recollection of some recent reading. Oh, wisdom of man and the apparatus of the sciences, the little columns of mercury that sling up and down, the vacuum boxes that expand and contract, the hammer that chips the highest rocks, the compass that takes the bearings of glacier and ridge—all the equipage of hypsometry and geology and geodesy—how pitifully feeble and childish it seems to cope with the majesty of the mountains! Take them all together, haul them up the steep, and as they lie there, read, recorded, and done for, which shall be more adequate to the whole scene—their records?—or that simple, ancient hymn, “We praise Thee, O God!—Heaven and earth are full of the majesty of Thy Glory!” What an astonishing thing that, standing where we stood and seeing what we saw, there are men who should be able to deduce this [Pg 110]law or that from their observation of its working and yet be unable to see the Lawgiver!—who should be able to push back effect to immediate cause and yet be blind to the Supreme Cause of All Causes; who can say, “This is the glacier’s doing and it is marvellous in our eyes,” and not see Him “Who in His Strength setteth fast the mountains and is girded with power,” Whose servants the glaciers, the snow, and the ice are, “wind and storm fulfilling His Word”; who exult in the exercise of their own intelligences and the playthings those intelligences have constructed and yet deny the Omniscience that endowed them with some minute fragment of Itself! It was not always so; it was not so with the really great men who have advanced our knowledge of nature. But of late years hordes of small men have given themselves up to the study of the physical sciences without any study preliminary. It would almost seem nowadays that whoever can sit in the seat of the scornful may sit in the seat of learning. <div class="sidenote">The Scientists</div> A good many years ago, on an occasion already referred to, the writer roamed through the depths of the Grand Cañon with a chance acquaintance who described himself as “Herpetologist to the Academy of Sciences” in some Western or Mid-Western State, and as this gentleman found the [Pg 111] curious little reptiles he was in search of under a root or in a cranny of rock he repeated their many-syllabled names. Curious to know what these names literally meant and whence derived, the writer made inquiry, sometimes hazarding a conjectural etymology. To his astonishment and dismay he found this “scientist,” whom he had looked up to, entirely ignorant of the meaning of the terms he employed. They were just arbitrary terms to him. The little hopping and crawling creatures might as well have been numbered, or called x, y, z, for any significance their formidable nomenclature held for him. Yet this man had been keenly sarcastic about the Noachian deluge and had jeered from the height of his superiority at hoary records which he knew only at second-hand reference, and had laid it down that if the human race became extinct the birds would stand the best chance of “evolving a primate”! Since that time other “scientists” have been encountered, with no better equipment, with no history, no poetry, no philosophy in any broad sense, men with no letters—illiterate, strictly speaking—yet with all the dogmatism in the world. Can any one be more dogmatic than your modern scientist? The reproach has passed altogether to him from the theologian. [Pg 112] The thing grows, and its menace and scandal grow with it. Since coming “outside” the writer has encountered a professor at a college, a Ph.D. of a great university, who confessed that he had never heard of certain immortal characters of Dickens whose names are household words. We shall have to open Night-Schools for Scientists, where men who have been deprived of all early advantages may learn the rudiments of English literature. One wishes that Dickens himself might have dealt with their pretensions, but they are since his day. And surely it is time some one started a movement for suppressing illiterate Ph.D.’s. <div class="sidenote">The Psalmist and Dr. Johnson</div> Of this class, one feels sure, are the scientific heroes of the sensational articles in the monthly magazines of the baser sort, of which we picked up a number in the Kantishna on our way to the mountain. Here, in a picture that seems to have obtruded itself bodily into a page of letter-press, or else to have suffered the accidental irruption of a page of letter-press all around it, you shall see a grave scientist looking anxiously down a very large microscope, and shall read that he has transferred a kidney from a cat to a dog, and therefore we can no longer believe in the immortality of the soul; or else that he has succeeded in artificially fertilizing the ova of a starfish—or was [Pg 113]it a jellyfish?—and therefore there is no God; not just in so many bald words, of course, but in unmistakable import. Or it may be—so commonly does the crassest credulity go hand in hand with the blankest scepticism—he has discovered the germ of old age and is hot upon the track of another germ that shall destroy it, so that we may all live virtually as long as we like; which, of course, disposes once for all of a world to come. The Psalmist was not always complaisant or even temperate in his language, but he lived a long time ago and must be pardoned; his curt summary stands: “Dixit insipiens!” But the writer vows that if he were addicted to the pursuit of any branch of physical knowledge he would insist upon being called by the name of that branch. He would be a physiologist or a biologist or an anatomist or even a herpetologist, but none should call him “scientist.” As Doll Tearsheet says in the second part of “King Henry IV”: “These villains will make the word as odious as the word ‘occupy’; which was an excellent good word before it was ill-sorted.” If Doctor Johnson were compiling an English dictionary to-day he would define “scientist” something thus: “A cant name for an experimenter in some department of physical knowledge, [Pg 114] commonly furnished with arrogance and dogmatism, but devoid of real learning.” Here is no gibe at the physical sciences. To sneer at them were just as foolish as to sneer at religion. What we could do on this expedition in a “scientific” way we did laboriously and zealously. We would never have thought of attempting the ascent of the mountain without bringing back whatever little addition to human knowledge was within the scope of our powers and opportunities. Tatum took rounds of angles, in practice against the good fortune of a clear day on top, on every possible occasion. The sole personal credit the present writer takes concerning the whole enterprise is the packing of that mercurial barometer on his back, from the Tanana River nearly to the top of the mountain, a point at which he was compelled to relinquish it to another. He has always had his opinion about mountain climbers who put an aneroid in their pocket and go to the top of a great, new peak and come down confidently announcing its height. But when all this business is done as closely and carefully as possible, and every observation taken that there are instruments devised to record, surely the soul is dead that feels no more and sees no further than the instruments do, that stirs with no other [Pg 115] emotion than the mercury in the tube or the dial at its point of suspension, that is incapable of awe, of reverence, of worshipful uplift, and does not feel that “the Lord even the most mighty God hath spoken, and called the world from the rising of the sun even to the going down of the same,” in the wonders displayed before his eyes. <hr style='width: 45%;' /> We reached our eighteen-thousand-foot camp about five o’clock, a weary but happy crew. It was written in the diary that night: “I remember no day in my life so full of toil, distress, and exhaustion, and yet so full of happiness and keen gratification.” <div class="sidenote">The Amber Glasses Again</div> The culminating day should not be allowed to pass without another tribute to the efficiency of the amber glasses. Notwithstanding the glare of the sun at twenty thousand feet and upward, no one had the slightest irritation of the eyes. There has never been an April of travel on the Yukon in eight years that the writer has not suffered from inflammation of the eyes despite the darkest smoke-colored glasses that could be procured. A naked candle at a road-house would give a stab of pain every time the eyes encountered it, and reading would become almost impossible. The amber glasses, however, while leaving vision [Pg 116] almost as bright as without them, filter out the rays that cause the irritation and afford perfect protection against the consequences of sun and glare. There is only one improvement to make in the amber glasses, and that is some device of air-tight cells that shall prevent them from fogging when the cold on the outside of the glass condenses the moisture of perspiration on the inside of the glass. We use double-glazed sashes with an air space between on all windows in our houses in Alaska and find ourselves no longer incommoded by frost on the panes; some adaptation of this principle should be within the skill of the optician and would remove a very troublesome defect in all snow-glasses. If some one would invent a preventive against shortness of breath as efficient as amber glasses are against snow-blindness, climbing at great altitudes would lose all its terrors for one mountaineer. So far as it was possible to judge, no other member of the party was near his altitude limit. There seemed no reason why Karstens and Walter in particular should not go another ten thousand feet, were there a mountain in the world ten thousand feet higher than Denali, but the writer knows that he himself could not have gone much higher. <hr style="width: 65%;" /> [Pg 117] <div style="break-after:column;"></div>
