"It's the curse of coming back, and the mere fact that your heart continues to tick forces that upon you. There is only one way—one way to dodge the mortgage I would place upon my Future by spending these savings."

"And that?"

"Not to let the heart tick on; to bar the future."

Donaldson moved a bit uneasily. As he did so the pup lost his balance and fell to the floor. The little fellow struck upon his side but instantly regained his feet, blinking sleepily at the light. Barstow took out his watch and squatting nearer him studied him with interest.

Suddenly the dog's legs crumpled beneath him. He tried to stand, to make his way to his master, but instantly toppled over on his side. Donaldson reached for him. That which he lifted was like a limp glove. He drew back from it in horror, glancing up at Barstow.

"You see," exclaimed the chemist with evident satisfaction, "almost to the hour!"

"But he isn't—"

"Dead!"

"Poor Sandy! Poor Sandy!"

Donaldson gingerly passed his fingers over the dog's hair. He was curiously unconvinced. There was no responsive lift of the head, no contented wagging of the tail, but that was the only difference. A moment ago the dog had been asleep for an hour; now he was asleep for an eternity. That was the only difference.
