Westy Martin in the Rockies by Percy Keese Fitzhugh

If it was natural that Uncle Jeb should have selected Westy to accompany him to Montana, it seemed quite as natural that Westy should select Artie to be his companion on the big adventure. At camp it was taken for granted that he would do this, not only because Artie was in Westy's troop and the two were pals, but because Artie was often with Uncle Jeb, and was serviceable to him in many ways. He was a frequent if not a steady helper.

Since work on the new trail had progressed to the opposite side of the lake from camp, the toilers saw much of him. They would hear the steady clink of oarlocks as the boat approached the shore and then Artie's voice calling from below, "Are you hungry up there? Any big rocks that you can't handle? If so, say the word; now's your chance. " Then he would come scrambling up, all out of breath, to where the work was going on. They enjoyed his visits. Everybody liked Artie.
