They did as directed, and then the representatives prepared to depart.

“The film, machine, and other equipment will be here inside of a week,” Mr. Duncan said. “And you’ll find it as simple as we explained.”

Then they took their leave.

“A chance to make some money,” said Mr. Lewis to the youths, as they seated themselves on the porch awaiting the evening meal.

“Yes,” said Bob. “And I know we’ll find it interesting.”

“What kind of a camera do you suppose they’ll furnish?” Joe asked.

“Probably the small, simple kind that requires no tripod. All you do is press a button and the film is automatically exposed. But you’ll have to follow the instructions closely or the whole thing will be a total failure. And to a certain extent, Mr. Holton and I will be held responsible.”

Practically all of the next day was spent in the business district purchasing various articles to be used on the coming great adventure. In the evening when they returned home they were satisfied with everything they had bought. Bob and Joe were especially delighted with the new rifles that their fathers presented them, for they were of the very latest design.

“I suppose they’ll bring down anything,” said Bob, in reference to the guns.

“Anything but elephants, rhinos, and the like that have extremely tough hides,” his father answered. “You needn’t fear them, though, for we won’t come across them in South America.”
