“Won’t it be difficult?” he asked.

“On the contrary,” Mr. Duncan returned. “Very simple. Hardly anything to it. We’ll give you complete instructions and will not hold you strictly responsible for any lost film. In fact it nearly always happens that at least several score feet of film are lost on such an expedition, where wet and damp have so much to do with the success of the pictures taken.”

“Of course,” said Mr. Weslowe, “we realize that yours will be an expedition for the good of science, not to take moving pictures. It is for this reason that we will willingly place the responsibility, which isn’t very much, in the hands of these young men here—your sons.

“Now this will not mean,” he assured them, “that they must put in all their time for this cause. We only wish several scenes along the journey. For instance, you might start by taking a movie of Pará, or whatever other city you first reach. Then several hundred feet may be used along the mainstream of the Amazon, showing the gradual progress of the expedition. When you turn onto a less-known river, that’s when we want the real show to start. The country you’ll pass through will be wilder, and the pictures will be more interesting. But once again let me assure you that the apparatus we’ll furnish will be of the simplest design, and you need not worry about not meeting with success as far as that goes. And we’ll pay you well for your trouble. Here’s the contract. Read it over. See what you think of it.”

He passed the paper to Mr. Holton, who shared the reading with Bob, Joe, and Mr. Lewis.


CHAPTER VI
Off for the Wilds of Brazil

“WELL?”

It was Mr. Weslowe’s voice after the scientists and their sons had finished reading the contract.
