Each pair will keep along until our watches show that we've been going ten minutes.

Then we will walk up the slope a hundred steps and turn toward the centre, meeting probably about the end of the second ten minutes.

After that, if we decide to do so, we can go further inland from the lake.

If there's a house or hut, or any fellow camping out in this neighborhood we ought to find him without much trouble.

What do you fellows say to my plan ?" "It's about as systematic as anything could be," Dave agreed.
"But what if one pair of us find something ?" "We'll try our best to communicate with the other pair," Dick rejoined.
