“For a little while, Dick,” laughed Jack; “but you won’t say anything when I show you the enlargement. You will be perfectly satisfied at having waited a little.”
“All right,” muttered both boys.
Jack had all the appliances for making an enlargement, and he could do it as well by night as in daylight, having flash powders which would give an instant’s light or be continued for as long as he chose, together with plates, paper and everything convenient.
The boys watched him at work and were greatly interested, now and then catching the sound of the Hilltop boys singing outside, but generally paying little attention to anything except what was going on just around them.
In the course of something more than an hour Jack had completed his work and showed a much larger print of Billy’s pinhole photograph than was possible from the original plate, and also a print from the latter.
“Now look at these two, first the little one and then the big,” he said, “and tell me what is the difference.”
“You’ve got an eight by ten, and mine is less than a four by five,” answered Billy. “The figures are naturally four times as large. By Jinks! you have a handsome picture, Jack.”
“Yes, but tell me what you see on one that you don’t see on the other. You should see it on both, of course, but it stands out stronger in the enlargement, as it naturally would.”
Percival looked at the larger picture and said:
“Hello! there is a man looking out from among the rocks on the ledge. Did you know he was there, Billy?”
