<h5 id="id00226">THE HOUSE OF THE HELIOGRAPH</h5>
<p id="id00227" style="margin-top: 2em">"You know your way about London?" he asked.</p>
<p id="id00228">"Yes, sir," said Harry.</p>
<p id="id00229">"I shall have messages for you to carry," said the colonel, then. "Now I
want to explain, so that you will understand the importance of this, why
you are going to be allowed to do this work. This war has come
suddenly—but we are sure that the enemy has expected it for a long
time, and has made plans accordingly.</p>
<p id="id00230">"There are certain matters so important, so secret, that we are afraid
to trust them to the telephone, the telegraph—even the post, if that
were quick enough! In a short time we shall have weeded out all the
spies. Until then we have to exercise the greatest care. And it has been
decided to accept the offer of Boy Scouts because the spies we feel we
must guard against are less likely to suspect boys than men. I am going
to give you some dispatches now—what they are is a secret. You take
them to Major French, at Waterloo station."</p>
<p id="id00231">He stopped, apparently expecting them to speak. But neither said
anything.</p>
<p id="id00232">"No questions?" he asked, sternly.</p>
<p id="id00233">"N$1—$2 sir," said Dick. "We're to take the dispatches to Major French,
at Waterloo? That all, is it, sir? And then to come back here?"</p>
<p id="id00234">The colonel nodded approvingly.</p>
<p id="id00235">"Yes, that's all," he said. "Except for this. Waterloo station is closed
to all civilians. You will require a word to pass the sentries. No
matter what you see, once you are inside, you are not to describe it.
You are to tell no one, not even your parent—what you do or what you
see. That is all," and he nodded in dismissal.</p>
<p id="id00236">They made their way out and back to the railway station. And Dick seemed
a little disappointed.</p>
<p id="id00237">"I don't think this is much to be doing!" he grumbled.</p>
<p id="id00238">But Harry's eyes were glistening.</p>
<p id="id00239">"Don't you see?" he said, lowering his voice so they could not be
overheard. "We know something now that probably even a lot of the
soldiers don't know! They're mobilizing. If they are going to be sent
from Waterloo it must mean that they're going to Southampton—and that
means that they will reach France. That's what we'll see at Waterloo
station—troops entraining to start the trip to France. They're going to
fight over there. Everyone is guessing at that—a lot of people thought
most of the army would be sent to the East Coast. But that can't be so,
you see. If it was, they would be starting from King's Cross and
Liverpool street stations, not from Waterloo."</p>
<p id="id00240">"Oh, I never thought of that!" said Dick, brightening.</p>
<p id="id00241">When they got on the train at Ealing they were lucky enough to get a
compartment to themselves, since at that time more people were coming to
Ealing than were leaving it. Dick began at once to give vent to his
wonder.</p>
<p id="id00242">"How many of them do you suppose are going?" he cried. "Who will be in
command? Sir John French, I think. Lord Kitchener is to be War Minister,
they say, and stay in London. I bet they whip those bally Germans until
they don't know where they are—"</p>
<p id="id00243">"Steady on!" said Harry, smiling, but a little concerned, none the less.<br/>
"Dick, don't talk that! You don't know who may be listening!"<br/></p>
<p id="id00244">"Why, Harry! No one can hear us—we're alone in the carriage!"</p>
<p id="id00245">"I know, but we don't know who's in the next one or whether they can
hear through or not. The wall isn't very thick, you know. We can't be
too careful. I don't think anyone knows what we're doing but there isn't
any reason why we should take any risk at all."</p>
<p id="id00246">"No, of course not. You're right, Harry," said Dick, a good deal
abashed. "I'll try to keep quiet after this."</p>
<p id="id00247">"I wonder why there are two of us," said Dick presently, in a whisper.<br/>
"I should think one would be enough."<br/></p>
<p id="id00248">"I think we've both got just the same papers to carry," said Harry, also
in a whisper. "You see, if one of us gets lost, or anything happens to
his papers, the other will probably get through all right. At least it
looks that way to me."</p>
<p id="id00249">"Harry," said Dick, after a pause, "I've got an idea. Suppose we
separate and take different ways to get to Waterloo? Wouldn't that make
it safer? We could meet there and go back to Ealing together."</p>
<p id="id00250">"That's a good idea, Dick," said Harry. He didn't think that their
present errand was one of great importance, in spite of what Colonel
Throckmorton had said. He thought it more likely that they were being
tried out and tested, so that the colonel might draw his own conclusions
as to how far he might safely trust them in the future. But he repressed
his inclination to smile at this sudden excess of caution on Dick's
part. It was a move in the right direction, certainly.</p>
<p id="id00251">"Yes, we'll do that," he said. "I'll walk across the bridge, and you can
take the tube under the river from the Monument."</p>
<p id="id00252">They followed that plan, and met without incident at the station. Here
more than ever the fact of war was in evidence. A considerable space in
and near the station had been roped off and sentries refused to allow
any to pass who could not prove that they had a right to do so. The
ordinary peaceful vocation of the great terminal was entirely suspended.</p>
<p id="id00253">"Anything happen to you?" asked Harry with a smile. "I nearly got run
over—but that was my own fault."</p>
<p id="id00254">"No, nothing. I saw Graves. And he wanted to know what I was doing."</p>
<p id="id00255">"What did you tell him?"</p>
<p id="id00256">"Nothing. I said, 'Don't you wish you knew?' And he got angry, and said
he didn't care."</p>
<p id="id00257">"It wasn't any of his business. You did right," said Harry.</p>
<p id="id00258">They had to wait a few moments to see Major French, who was exceedingly
busy. They need no one to tell them what was going on. At the platform
trains were waiting, and, even while they looked on, one after another
drew out, loaded with soldiers. The windows were whitewashed, so that,
once the doors of the compartments were closed, none could see who was
inside. There was no cheering, which seemed strange at first, but it was
so plain that this was a precautionary measure that the boys understood
it easily enough. Finally Major French, an energetic, sunburned man, who
looked as if he hadn't slept for days, came to them. They handed him the
papers they carried. He glanced at them, signed receipts which he handed
to them, and then frowned for a moment.</p>
<p id="id00259">"I think I'll let you take a message to Colonel Throckmorton for me," he<br/>
said, then, giving them a kindly smile. "It will be a verbal message.<br/>
You are to repeat what I tell you to him without a change. And I suppose<br/>
I needn't tell you that you must give it to no one else?"<br/></p>
<p id="id00260">"No, sir," they chorused.</p>
<p id="id00261">"Very well, then. You will tell him that trains will be waiting below
Surbiton, at precisely ten o'clock tonight. Runways will be built to let
the men climb the embankment, and they can entrain there. You will
remember that?"</p>
<p id="id00262">"Yes, sir."</p>
<p id="id00263">"You might as well understand what it's all about," said the major. "You
see, we're moving a lot of troops. And it is of the utmost importance
for the enemy to know all about the movement and, of course, just as
important for us to keep them from learning what they want to know. So
we are covering the movement as well as we can. Even if they learn some
of the troops that are going, we want to keep them from finding out
everything. Their spy system is wonderfully complete and we have to take
every precaution that is possible. It is most important that you deliver
this message to Colonel Throckmorton. Repeat it to me exactly," he
commanded.</p>
<p id="id00264">They did so, and, seemingly satisfied, he let them go. But just as they
were leaving, he called them back.</p>
<p id="id00265">"You'd go back by the underground, I suppose," he said. "I'm not sure
that you can get through for the line is likely to be taken over,
temporarily, at any moment. Take a taxicab—I'll send an orderly with
you to put you aboard. Don't pay the man anything; we are keeping a lot
of them outside on government service, and they get their pay from the
authorities."</p>
<p id="id00266">The orderly led them to the stand, some distance from the station, where
the cabs stood in a long row, and spoke to the driver of the one at the
head of the rank. In a moment the motor was started, and they were off.</p>
