Women, for one thing, do not usually smoke dozens of rank cigars daily for years, until their flesh is permeated with the smell of tobacco. A human could not have detected such a smell—such a MAN-smell,—on the person who had chirped to Bruce. Any dog, twenty feet away, would have noticed it, and would have tabulated the white-clad masquerader as a man. Nor do a woman's hair and skin carry the faint but unmistakable odor of barracks and of tent-life and of martial equipment, as did this man's. The masquerader was evidently not only a man but a soldier.
Dogs,—high-strung dogs,—do not like to have tricks played on them; least of all by strangers. Bruce seemed to take the nurse-disguise as a personal affront to himself. Then, too, the man was not of his own army. On the contrary, the scent proclaimed him one of the horde whom Bruce's friends so manifestly hated—one of the breed that had more than once fired on the dog.
Diet and equipment and other causes give a German soldier a markedly different scent, to dogs' miraculously keen nostrils,—and to those of certain humans,—from the French or British or American troops. War records prove this. Once having learned the scent, and having learned to detest it, Bruce was not to be deceived.
For all these reasons he had snarled loathingly at the man in white. For these same reasons he could not readily forget the incident, but continued every now and then to glance curiously across toward the church.
Presently,—not relishing the rebukes of the friends who had heretofore pestered him by overmuch petting,—the collie arose quietly from his couch of trampled earth at the foot of the stone bench and strolled back across the street. Most of the men were too busy, talking, to note Bruce's departure. But Sergeant Mahan caught sight of him just as the dog was mounting the last of the steps leading into the church.
As a rule, when Bruce went investigating, he walked carelessly and with his tail slightly a-wag. Now his tail was stiff as an icicle, and he moved warily, on the tips of his toes. His tawny-maned neck was low. Mahan, understanding dogs, did not like the collie's demeanor. Remembering that the nurse had entered the church a few minutes earlier, the Sergeant got to his feet and hastily followed Bruce.
The dog, meanwhile, had passed through the crazily splintered doorway and had paused on the threshold of the improvised hospital, as the reek of iodoform and of carbolic smote upon his sensitive nostrils. In front of him was the stone-paved vestibule. Beyond was the interior of the shattered church, lined now with double rows of cots.
Seated on a camp-chair in the shadowy vestibule was the pseudo Red Cross nurse. At sight of the collie the nurse got up in some haste. Bruce, still walking stiff-legged, drew closer.
Out from under the white skirt flashed a capable and solidly-shod foot. In a swinging kick, the foot let drive at the oncoming dog. Before Bruce could dodge or could so much as guess what was coming,—the kick smote him with agonizing force, square on the shoulder.
To a spirited collie, a kick carries more than the mere pain of its inflicting. It is a grossly unforgivable affront as well—as many a tramp and thief have learned, at high cost.
