"I can wait."

"Thank you. The mission closes at eleven. If you can wait till then you might come home with me, and we could talk in comfort."

It was nine o'clock. For two hours Warrisden followed Chase about the mission, and with each half-hour his interest increased. However irreconcilable with his surroundings Chase might appear to be, neither he nor any of the members of the mission were aware of it. He was at ease alike with the boys and the men; and the boys and the men were at ease with him. Moreover, he was absolute master, although there were rough men enough among his subjects. The fiercest boxing contest was stopped in a second by a motion of that delicate hand.

"I used to have a little trouble," he said to Warrisden, "before I had those wire frames fixed over the gas-jets. You see they cover the gas taps. Before that was done, if there was any trouble, the first thing which happened was that the room was in darkness. It took some time to restore order;" and he passed on to the swimming-bath.

Mr. Chase was certainly indefatigable. Now he was giving a lesson in wood-carving to a boy; now he was arranging an apprenticeship for another in the carpenter's shop. Finally he led the way into the great billiard-room, where only the older men were allowed.

"It is here that Stretton used to keep order?" said Warrisden; and Chase at once turned quickly towards him.

"Oh," he said slowly, in a voice of comprehension, "I was wondering what brought you here. Yes; this was the room."

Chase moved carelessly away, and spoke to some of the men about the tables. But for the rest of the evening he was on his guard. More than once his eyes turned curiously and furtively towards Warrisden. His face was stubborn, and wore a look of wariness. Warrisden began to fear lest he should get no answer to the question he had to put. No appeal would be of any use--of that he felt sure. His argument must serve--and would it serve?

Chase, at all events, made no attempt to avoid the interview. As the hands of the clock marked eleven, and the rooms emptied, he came at once to Warrisden.

"We can go now," he said; and unlocking a drawer, to Warrisden's perplexity he filled his pockets with racket-balls. The motive for that proceeding became apparent as they walked to the house where Chase lodged. Their way lay through alleys, and as they walked the children clustered about them, and Chase's pockets were emptied.
