If you get tired, or find it hard, just come over to the brook and follow it down to camp.
If you get there ahead of us you might start a fire in our tent stove and put the kettle over." "I've got plenty o' grit, sir," Jamie boasted.

"I can stand un." "I think you can," agreed Doctor Joe, "but your legs are short.

If you get tired don't keep going.

Perhaps you had better take the outside place, and if you do get tired and fall out it won't break the line." Full of eagerness and excitement, the boys took their positions.
