"I perhaps did not tell you that I am a sort of inventor," the Spaniard went on. "I have not had much success, but I think my new alarm clock is going to bring me in some money. It works on a new principle, but I am giving it a good test, privately, before I try to put it on the market."

He took the brass-bound, ticking box from the bed, and must have adjusted the mechanism in a way Blake or Joe did not notice, for the "click-click" stopped at once, and the room seemed curiously still after it.

"Some day I will show you how it works," the young Spaniard went on. "I think, myself, it is quite what you call—clever."

And with that he put the box in a trunk, and closed the lid with a snap that threw the lock.

"And now, boys, we will soon be there!" he cried with a gay laugh. "Soon we will be in the beautiful land of Panama, and will see the marvels of that great canal. Are you not glad? And I shall begin to learn more about making moving pictures! That will please me, though I hope I shall not be so stupid a pupil as to make trouble for you, my friends, to whom I owe so much."

He looked eagerly at the boys.

"We'll teach you all we know, which isn't such an awful lot," said Joe. "And I don't believe you'll be slow."

"You have picked up some of it already," went on Blake, for while delaying over making their arrangements in New York the boys and their pupil had gone into the rudiments of moving picture work.

"I am glad you think so," returned the other. "I shall be glad when we are at work, and more glad still, when I can, with my own camera, penetrate into the fastness of the jungle, along the lines of our railroad, and show what we have done to bring civilization there. The film will be the eyes of the world, watching our progress," he added, poetically.

"Why don't you come up on deck," he proceeded. "It is warm down here."
