A mile or two down the road Larsen turned into the fields. Across his saddle was something the young pointer had had no experience with--a gun. That part of his education Thompson had neglected, or at least postponed, for he had not expected that Comet would be sent away so soon. That was where Thompson had made a mistake. At the command "Hie on!" the young pointer ran eagerly around the horse, looking up into the man's face to be sure he had heard aright. Something he saw there made him momentarily droop his ears and tail. Again there came over him the feeling of strangeness, of homesickness, mingled this time with dismay. Larsen's eyes were slits of blue glass. His mouth was set in a thin line. Had Comet seen a different expression, had he received a single word of encouragement, there would have been no calamity that day. If he had trusted the man, he would have withstood the shock his nerves were about to receive. But he did not trust this pale man with the strange eyes and the hard-set mouth. At a second command, though, he galloped swiftly, boldly into the field. Once he turned for direction and Larsen waved him on. Round and round the extensive field he circled, forgetting any feeling of strangeness, every fibre of his being intent on the hunt. Larsen, from his horse, watched with appraising eyes. Suddenly to the young dog's nose came the smell, strong, pungent, compelling, of game birds. He stiffened into an earnest beautiful point. Heretofore, in the little training he had gone through, Thompson had come up behind him, flushed the birds and made him drop. And now Larsen, having quickly dismounted and tied his horse, hurried toward him as Thompson had done--except that in Larsen's hand was the gun. The old-fashioned black powder of a generation ago makes a loud explosion. It sounds like a cannon compared with the modern smokeless powder used for almost a generation by nearly all hunters. Perhaps it was merely accident that had caused Larsen before he left the house to load his pump gun with black-powder shells. As for Comet, he only knew that the birds rose with a whirr, and that then, above his head, burst an awful roar, almost splitting his ear drums, shocking every sensitive nerve, filling him with terror such as he had never felt before. Even then in the confusion and horror of the noise he turned to the man, ears ringing, eyes dilated. As for Larsen, he declared afterward, to others and to himself even, that he noticed no nervousness in the dog, that he was intent only on getting several birds for breakfast. Twice, three times, four times the pump gun bellowed its cannon-like roar, piercing the ear drums, shattering the nerves. Comet turned. One more glance backward at a face, pale, exultant. Then the puppy in him conquered. Tail tucked, he ran away from that blasting noise.
