"Oh, look at the funny boats!" exclaimed Tom, pointing to the long line of river steamers that were tied up at the levee. "What are those things on the back end?"

"They are the paddle wheels. I know, because I've looked at pictures like them in my geography," replied Larry. "They have the paddle wheels on the end because the water is so shallow in places."

It was Just after noon that the two chums and Hans were vouchsafed a glimpse of real "dyed-in-the-wool" cowboys.

The train had stopped at a crossing, as stations are known in
Oklahoma, because of a hot-box on one of the wheels.

Learning that it would be all of a quarter of an hour before the trouble could be repaired, the boys had left their car and were filling their lungs with the bracing air.

It chanced that a gang of cowboys had ridden Into the town for a celebration and, as it was unusual for a train to stop for any length of time at the crossing, they rode up to find out the reason.

For a few minutes they contented themselves with putting their ponies through all sorts of "stunts" to the great delight of the people on the train.

At the sight of them, Larry, Tom and Hans walked toward the cowboys and stared at them in wonder and admiration.

The cowboys had noticed the three lads, and, because they had been drinking bad "fire-water," suddenly decided to amuse themselves with them.

"Whatcher lookin' at?" roared one of the cow-punchers, a big fellow with close-set eyes and a heavy jaw.
