“Hold your horses, there!” he called out, pulling back on Jupiter’s bridle, although the horse seemed unwilling to mind; “give a fellow a chance, won’t you? Don’t go and hog it all, just because we were considerate enough to let you drink first. Have some manners, can’t you, I say? Drag ’em back, boys, and let’s get a sup ourselves before it’s all gone.”

“No worry, Billie,” said Donald; “because, if you look sharp you’ll see that the spring is running at a lively rate, and the cup’ll fill up with fresh water right off. It creeps away under this rank vegetation, and is lost in the sand beyond. But there’s going to be plenty of water right along. Better let the ponies have all they want while we’re about it.”

So I was going to propose that we camp right here tonight.”

“Eureka! count on my vote in favor of that same!” cried Billie, promptly falling in with the scheme, as Donald knew full well he would; because if there was one thing the fat boy liked above all others it was fresh water; and there were times
