But Grenfell did not hesitate. From house to house he went, to rouse the occupants like another Paul Revere, and beg for dogs that he might use on the desperate journey.

One man let him take four. Another, for pay, gave him a fifth animal. A boy named Walter said he would get four more dogs and would drive the ill-assorted team. By that time it was midnight.

"We'll start at 4:30," said the Doctor. At 4:30 it would still be pitch-black.

Grenfell went back to the hospital, roused the head nurse, and went to every patient to make sure that while he was gone no accident would happen that he could possibly prevent.

At 4:30 he was ready to start. Few men are his match for staying up all night and looking as fresh as a mountain daisy after the vigil.

He opened the door and a blizzard swept in and tried to rush him off his feet. Through the whirling drift staggered Walter, dogless.

"Where are those dogs?" asked the Doctor. He expects men to keep agreements made with him. He couldn't get through the length and breadth of his big day's work if they didn't.

Walter shook his snow-covered head. "I ain't brought 'em, sir. It's too bad a night to be startin' before sun-up. The dogs don't know each other: they comes from here, there an' all over. They'll be fightin' in the traces an' eatin' each other up in the dark. Us must be able to see 'em in order to drive 'em. You know what dogs is like, sir."

"Yes, I do," said Grenfell. "But you're the driver, and I leave it to you. We must get off as soon as we can."

Dr. Grenfell went to his room to snatch a catnap before the start. Another telegram woke him as he was drowsing off.
