<h3>THINGS WERE TOPSY-TURVY ALOFT, TOO.</h3> <p>One evening, when Mr. Hall, astronomer, was working in the Naval Observatory, Washington, on the great equatorial telescope, he was startled to have his sanctum invaded by the gaunt, extenuated figure of the President. He was made welcome, of course, and the varied mechanism explained to him. As the crowning "treat," he was given a peer through the celebrated instrument. It was leveled at the moon, or, rather, arranged to have that orb in its focus at the time. The visitor was appalled, as well as wondering at the view, and slowly withdrew by the trap-door. But when the astronomer resumed his observations and calculations he was interrupted by the same sedate and absorbed caller. He returned, perplexed, as, on glancing up at the moon with unhindered vision, he saw it in another position to that presented in the spy-glass.</p> <p>Mr. Hall made it clear to him that, as the telescope was pointed, not at the satellite but at its image in a mirror, he saw its reflection and consequently the reverse of the face we observe. The President went away with the satisfaction of a man wanting every novelty demonstrated. <br/> <br/> <br/></p> <div style="break-after:column;"></div><br />
