But no answer was vouchsafed. Challis sighed. "Come along, Lewes," he said; "we must waste no more time."

Lewes wore a look of smug triumph as they went to the farther room, but he was clever enough to refrain from expressing his triumph in speech.

Challis gave directions that the window which the Wonder had found to be his most convenient method of entry and exit should be kept open, except at night; and a stool was placed under the sill inside the room, and a low bench was fixed outside to facilitate the child's goings and comings. Also, a little path was made across the flower-bed.

The Wonder gave no trouble. He arrived at nine o'clock every morning, Sunday included, and left at a quarter to six in the evening. On wet days he was provided with a waterproof which had evidently been made by his mother out of a larger garment. This he took off when he entered the room and left on the stool under the window.

He was given a glass of milk and a plate of bread-and-butter at twelve o'clock; and except for this he demanded and received no attention.

For three weeks he devoted himself exclusively to the study of the Encyclopædia.

Lewes was puzzled.

Challis spoke little of the child during these three weeks, but he often stood at the entrance to the farther rooms and watched the Wonder's eyes travelling so rapidly yet so intently down the page. That sight had a curious fascination for him; he returned to his own work by an effort, and an hour afterwards he would be back again at the door of the larger room. Sometimes Lewes would hear him mutter: "If he would only answer a few questions...." There was always one hope in Challis's mind. He hoped that some sort of climax might be reached when the Encyclopædia was finished. The child must, at least, ask then for another book. Even if he chose one for himself, his choice might furnish some sort of a test.

So Challis waited and said little; and Lewes was puzzled, because he was beginning to doubt whether it were possible that the child could sustain a pose so long. That, in itself, would be evidence of extraordinary abnormality. Lewes fumbled in his mind for another hypothesis.
