That it would be a wild, desolate place, he had no doubt, for the evidences of the telescopes of astronomers pointed that way, and, as is well known, the most powerful instruments can now bring the moon to within an apparent distance of one hundred miles of the earth. This is true of the Lick telescope, which has a magnifying power of 2,500 and an object lens a yard across. But, with this powerful telescope, it has been impossible to distinguish any such objects as forests, cities, or any evidences of life on the moon--that is, on the side that has always been turned toward us. Almost unconsciously, Mark went on faster than he intended, and, before he knew it, he had arrived at the barn where he had promised to wait for his chum. Mark looked at his watch, and found that he would still have some time to linger before he could expect Jack to return. He sat down on a stone beside the fence, and looked about him. The day was warm for fall, and the last of the crickets were chirping away, while, in distant fields, men could be seen husking corn, or drawing in loads of yellow pumpkins. "I wonder if we'll have pumpkin pie on the moon," thought Mark. "Though, of course, we won't. I guess all we'll have to eat will be what Washington takes along in the projectile--that is, unless we find people on the other side of the place." He sat on the stone for some minutes longer, and then, tiring of the inactivity, he arose and strolled about. Something seemed to draw him in the direction of the old house, which he knew was just around the bend in the road. "I guess there wouldn't be any harm in my going along and taking a peep at it," mused the lad. "It will be some time before Jack returns, and I may be able to catch a glimpse of our man. I think I'll go up where I can see the place, and I can come back in time to meet Jack. I'll do it. Maybe the fellow might escape while I'm waiting." Mark thus tried to justify himself for his action in not keeping to his agreement with his chum. Of course it was not an important matter, Mark thought, though the results of his simple action were destined to be more far-reaching than he imagined. He thought he would be back in time to meet Jack, and so he strolled on, going more cautiously now, for, in a few minutes he would come in sight of the old, deserted house, and he did not know what he might find there. Mark's first sight of the Preakness homestead was of two old stone posts, that had once formed a fine gateway. The posts were in ruins, now, and half fallen down, being covered with Virginia creeper, the leaves of which were now a vivid red, mingled with green. "Nothing very alarming there," said Mark, half aloud. He could just catch a glimpse of the roof of the house over the tops of the trees, which had not yet shed all their leaves. "Guess I'll go on a little farther. Maybe our friend, the enemy, is sitting on the front porch, sunning himself."
