The physician having a good business, and a large number of his patients being slaves,--the most of whom had to call on the doctor when ill,--he put Sam to bleeding, pulling teeth, and administering medicine to the slaves.

Sam soon acquired the name among the slaves of the "Black Doctor." With this appellation he was delighted; and no regular physician could have put on more airs than did the black doctor when his services were required.

In bleeding, he must have more bandages, and would rub and smack the arm more than the doctor would have thought of.
Sam was once seen taking out a tooth for one of his patients, and nothing appeared more amusing.

He got the poor fellow down on his back, and then getting astride of his chest, he applied the turnkeys and pulled away for dear life.

Unfortunately, he had got hold of the wrong tooth, and the poor man screamed as loud as he could; but it was to no purpose, for Sam had him fast, and after a pretty severe tussle out came the sound grinder.
