His anger was justified. Travel in the North, where food is scarce, is a question of transport. As the traveler must take all he needs with him, his supplies must be carefully regulated in accordance with the distance and his power of carrying them, while an error in his calculations may result in starvation. Knowing this, Carnally and Graham had considered how the weight could be cut down by the use of certain condensed foods, as well as clothing and camp equipment made to combine the greatest warmth with lightness. The goods were expensive, but their value could hardly be reckoned in money.

"Then we had better push on at once," Graham suggested. "We have the things Carnally sent up and we ought to get some provisions at the Hudson Bay factory, where I expect to hire the sledge dogs. It will add to our loads and shorten our stay, but we'll have to put up with that."

"You should have cut Mappin right out of this business," Carnally said to Andrew. "His first trick hasn't stopped us, but I feel uneasy about leaving him to handle the food we'll need when coming down."

Andrew looked grave.

"The man's treacherous; but he has gone as far as is safe already. Taking it for granted that he wishes to prevent our finding the lode, one can understand his trying to hinder our outward journey. He would, however, gain nothing by delaying our return, and he's too clever to risk getting himself into trouble without a good reason."

"That sounds right; I can find no fault with it," Carnally agreed. "We'll pull out to-morrow, but I'd feel easier if the making of those caches wasn't in Mappin's hands."

They left Rain Bluff the next morning and it was a week later when Mappin learned that he had failed to detain them. He had just returned to the Landing from a business visit, and was sitting in his room at the hotel when the messenger came in.

"Did Mr. Allinson seem annoyed?" he asked.

"Can't say," the man replied. "He didn't say a word to me; told Watson there was no answer, and pulled out with the other fellows next day."

"I suppose they went off with pretty heavy loads?"
