Again and again they stopped—and every time it proved that the dog was right.

On journey after journey of this kind, round about St. Anthony on that far northern peninsula of Newfoundland, Grenfell and the dogs he drove got to know and love one another better.

Grenfell has done seventy-five miles in a day easily: but how far one goes depends on the state of the ice and snow and the roughness of the trail: sometimes five miles a day is as much as the dogs, pulling their very hearts out, are able to cover. Six miles an hour is an average rate of speed when it is "good going." Once the Doctor made twenty-one miles in a little more than two hours, over level ice.

The building of the sled, or komatik, is a most important matter. The Doctor prefers one eleven feet long, of black spruce, with runners an inch thick, covered with spring steel. With such a sled, and a good team of dogs attached with proper traces, travel on firm and level snow is an exhilarating experience. But a thousand and one things may go wrong, the dogs when not running are forever picking bloody quarrels, and continual vigilance is the price of a swift, smooth passage.

A member of Grenfell's staff had crossed a neck of land between two bays, and was "twenty miles from anywhere," when his dogs struck the fresh trail of deer.

At such times the dogs are likely to take leave of all their senses save the instinct of the chase. These plucky beasts were no exception to the rule.

As they were short of food, the two teams were hitched to one sled, and the other sled, laden, was left in charge of a boy, while the men gave chase to the caribou. Like Casabianca on the burning deck, the boy had been told not to stir from that chilly, lonesome spot.

But just as the men got under way, a terrible snowstorm sprang up from nowhere, and so enveloped and bewildered the hunters that for two days they wandered, till they lost all hope.

Then, by great good luck, starving and worn out, they came to a little house many long and weary miles from where the boy was left with the komatiks.

They sent a relief team back to find him. There he was, standing by the sleds like a good, true soldier, just where they told him to remain. He was bound to be faithful unto death, even though he should freeze stiff for his obedience to orders.
