Then, all at once, into the sweet routine of the House of Peace, came Horror. It began on a blustery, sour October day. The Mistress had crossed the lake to the village, in her canoe, with Lad curled up in a furry heap in the prow. On the return trip, about fifty yards from shore, the canoe struck sharply and obliquely against a half-submerged log that a Fall freshet had swept down from the river above the lake. At the same moment a flaw of wind caught the canoe's quarter. And, after the manner of such eccentric craft, the canvas shell proceeded to turn turtle. Into the ice-chill waters splashed its two occupants. Lad bobbed to the top, and glanced around at the Mistress to learn if this were a new practical joke. But, instantly, he saw it was no joke at all, so far as she was concerned. Swathed and cramped by the folds of her heavy outing skirt, the Mistress was making no progress shoreward. And the dog flung himself through the water toward her with a rush that left his shoulders and half his back above the surface. In a second he had reached her and had caught her sweater-shoulder in his teeth. She had the presence of mind to lie out straight, as though she were floating, and to fill her lungs with a swift intake of breath. The dog's burden was thus made infinitely lighter than if she had struggled or had lain in a posture less easy for towing. Yet he made scant headway, until she wound one hand in his mane, and, still lying motionless and stiff, bade him loose his hold on her shoulder. In this way, by sustained effort that wrenched every giant muscle in the collie's body, they came at last to land. Vastly rejoiced was Lad, and inordinately proud of himself. And the plaudits of the Master and the Mistress were music to him. Indefinably, he understood he had done a very wonderful thing and that everybody on The Place was talking about him, and that all were trying to pet him at once. This promiscuous handling he began to find unwelcome. And he retired at last to his "cave" under the piano to escape from it. Matters soon quieted down; and the incident seemed at an end. Instead, it had just begun. For, within an hour, the Mistress--who, for days had been half-sick with a cold--was stricken with a chill, and by night she was in the first stages of pneumonia. Then over The Place descended Gloom. A gloom Lad could not understand until he went upstairs at dinner-time to escort the Mistress, as usual, to the dining-room. But to his light scratch at her door there was no reply. He scratched again and presently Master came out of the room and ordered him down-stairs again. Then from the Master's voice and look, Lad understood that something was terribly amiss. Also, as she did not appear at dinner and as he was for the first time in his life forbidden to go into her room, he knew the Mistress was the victim of whatever mishap had befallen.
