a man, one hot day, hired an ass, with his driver, to carry some merchandise across a sandy plain. the sun's rays were overpowering, and unable to advance farther without a temporary rest he called upon the driver to stop, and proceeded to sit down in the shadow of the ass.

the driver, however, a lusty fellow, rudely pushed him away, and sat down on the spot himself.

"nay, friend," said the driver, "when you hired this ass of me you said nothing about the shadow. if now you want that, too, you must pay for it."
