"Now," said Henry, "it will take you six weeks to pay me for these, at half a dollar a week."

Henry Martin continued to devote a part of every evening to study. He tried to prevail upon Sam to do the same, but without success.

"I get too tired to study," said Sam, and while his roommate was at home he was in the habit of strolling about the streets in search of amusement.

"Nowhere in particular," said Sam.

"Come into French's Hotel, and see them play billiards."

Sam complied.

There was one vacant table, and presently the other proposed a game.
