"Yes, I took it out to see how long it took me to make a box cover, and then Tom asked me to nail up that box containing the motor parts, and I laid my watch right down on top, and put the boards over it."
"Well, the only thing to do is to take off the cover," remarked Tom grimly.
"Bless my chronometer! That will delay things," said the odd man with a sigh. "But I suppose there is no hope for it," and he proceeded to open the box, while Tom, Ned, the circus man and Eradicate busied themselves over the hundred and one things to be done before they would be ready for the trip to the interior of South America.
"Look out, Ned!" called Tom. "You're making those top boards too long. They'll stick out over the edge, and be ripped off if the box catches on anything."
"Yes, you can't be too careful," cautioned Mr. Preston. "Each box or package must be the right weight, or the porters and mule drivers won't carry them into the interior. You may have to cross rough trails, and even ford rivers. And as for bridges! well, the less said about them the better. You aren't going to have any picnic, and if you want to back out, Tom Swift, now is the time to say so."
