I think I can make use of it

    "That is an idea. I think I can make use of it.".     That evening when Wheeler was present Mr. Pettigrew managed to turn the conversation to the subject of sleeping.     "I am a very sound sleeper," he said. "I remember when I was at home sleeping many a time through a severe thunder storm."     "Don't you sometimes wake up in the middle of the night?" asked Rodney.     "Very seldom, if I am in good health."     "Its different with me," said another of the company. "A step on the floor or the opening of the door will wake me up at any time."     "I am glad I am not so easily roused."     "If I had a fish horn," said Rodney, laughing, "I should be tempted to come up in the night and give it a blast before your door."     "That might wake me up," said Mr. Pettigrew. "I wouldn't advise you to try it or the other boarders might get up an indignation meeting."     The same evening Jefferson Pettigrew took out a bag of gold and carelessly displayed it.     "Are you not afraid of being robbed, Mr. Pettigrew?" asked Rodney.     "Oh no. I never was robbed in my life."     "How much money have you there?"     "I don't know exactly. Perhaps six hundred dollars," said Pettigrew in an indifferent tone.
