This was the bathing-place, and it was one of the best I have ever seen. The boat-houses were about half a mile down the river, and bathing and boating were two of the special features of Blackrock sports. The Doctor maintained (as every sensible person ought), that while cricket and foot-ball are desirable, swimming is essential, and he laid it down as a rule that everybody should learn to swim, and that on no account should a boy be allowed to enter a boat until he was a sufficiently good swimmer to get safely to shore, should his boat be upset.

Monday morning was as bright and warm as the previous evening had been cold and miserable. Lessons were studied in the grounds instead of in the class-rooms, and when the breakfast bell rang, there were not a few who were talking about the forthcoming bath and the evening row.

At prayers, Digby was absent. Not for the first time, within the recollection of many; but as he had not sent in any excuse for non-attendance, Howard and McDonald, who occupied the rooms next to his, were asked if they knew what had become of him. Neither of them did, but McDonald remarked that he was up earlier than usual, which was not considered at all remarkable, as the morning was deliciously warm and bright.

The Doctor looked displeased, but no further notice was taken before the boys, although he had made up his mind to administer a serious caution to Master Digby for irregularities, which latterly were becoming so frequent as to call for special notice.

The time for bathing was fixed for an hour after breakfast, the doctor holding that while the weather was unsettled, and the water cold, bathing was more beneficial a little while after a light meal than before.

A rush was made to the clump of trees, and a pell-mell scamper down the steep bank. When Mr. Featherstone, one of the masters, came up two minutes after with some of the older boys, amongst whom were Martin and Howard, he was surprised to hear his name called loudly by several of the boys.

“What’s wrong?” he asked.

“Digby Morton’s clothes are on the bank,” cried Aleck Fraser, excitedly, “but we can’t see him anywhere.”

Mr. Featherstone had all his wits about him. He knew the rough stepping-places up to the head of the Blackrock, from which he could scan the river up and down. In a moment he was standing on the rock, carefully taking within his view every yard of ground within range; but he could see nothing of Digby.

“Martin Venables,” he shouted from the rock, “run to the house, and ask the Doctor to come here at once. Howard and Aleck hurry down to the boat-house, and inquire about Morton. Send the boatman up at once with boats and men. McDonald and Marsden, go up to the meadow-dell and search. Look sharp, all of you!”
