"That's one swell way for a decently bred dog to treat a woman!" Mahan was telling him. "Least of all, a Red Cross nurse! I'm clean ashamed of you!"

Bruce did not listen. In his heart he was still angry--and very much perplexed as well. For he knew what these stupid humans did not seem to know.

HE KNEW THE RED CROSS NURSE WAS NO WOMAN AT ALL, BUT A MAN.

Bruce knew, too, that the nurse did not belong to his loved friends of the Red Cross. For his uncanny power of scent told him the garments worn by the impostor belonged to some one else. To mere humans, a small and slender man, who can act, and who dons woman's garb, is a woman. To any dog, such a man is no more like a woman than a horse with a lambskin saddle-pad is a lamb. He is merely a man who is differently dressed from other men--even as this man who had chirped to Bruce, from the church steps, was no less a man for the costume in which he had swathed his body. Any dog, at a glance and at a sniff, would have known that.

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 pa.s.sed 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.

By the time the kick had fairly landed, Bruce had recovered from his instant of incredulous surprise; and with lightning swiftness he hurled himself at his a.s.sailant.

No bark or growl heralded the murderous throatlunge. It was all the more terrible for the noiselessness wherewith it was delivered. The masquerading man saw it coming, just too late to guard against it. He lurched backward, belatedly throwing both hands up to defend his throat. It was the involuntary backward step which saved his jugular.

For his heel caught in the hem of his white skirt. And wholly off balance, he pitched headlong to the floor.

This jerky shift of position, on the part of the foe, spoiled Bruce's aim. His fearful jaws snapped together harmlessly in empty air at a spot where, a fraction of a second earlier, the other's throat had been. Down crashed the disguised man. And atop of him the furious dog hurled himself, seeking a second time the throatgrip he had so narrowly missed.

At this point on the program Sergeant Mahan arrived just in time to bury both hands in the ma.s.s of Bruce's furry ruff and to drag the snarlingly rabid dog back from his prey.

The place was in an uproar. Nurses and doctors came rushing out into the vestibule; sick and wounded men sat up on their cots and eagerly craned their necks to catch sight of the scrimmage. Soldiers ran in from the street.

Strong as he was, Mahan had both hands full in holding the frantic Bruce back from his enemy. Under the insult of the kick from this masquerader, whom he had already recognized as a foe, the collie had temporarily lost every vestige of his stately dignity. He was for the moment merely a wild beast, seeking revenge for a brutal injury. He writhed and fought in Mahan's grasp. Never once did he seek to attack the struggling man who held him. But he strained every giant sinew to get at the foe who had kicked him.

The dog's opponent scrambled to his feet, helped by a dozen willing hands and accosted by as many solicitous voices. The victim's face was bone-gray with terror. His lips twitched convulsively. Yet, as befitted a person in his position, he had a splendid set of nerves. And almost at once he recovered partial control over himself.

"I--I don't know how it happened," he faltered, his rich contralto voice shaky with the ground-swells of his recent shock. "It began when I was sitting on the steps, sewing. This dog came past. He growled at me so threateningly that I came indoors. A minute later, while I was sitting here sewing, he sprang at me and threw me down. I believe he would--would have killed me," the narrator finished, with a very genuine shudder, "if I had not been rescued when I was. Such bloodthirsty brutes ought to be shot!"

"He not only OUGHT to be," hotly agreed the chief surgeon, "but he is GOING to be. Take him out into the street, one of you men, and put a ball in his head."

The surgeon turned to the panting nurse.

"You're certain he didn't hurt you?" he asked. "I don't want a newcomer, like yourself, to think this is the usual treatment our nurses get. Lie down and rest. You look scared to death. And don't be nervous about the cur attacking you again. He'll be dead inside of three minutes."

The nurse, with a mumbled word of thanks, scuttled off into the rear of the church, where the tumbledown vestry had been fitted up as a dormitory.

Bruce had calmed down somewhat under Mahan's sharp reproof. But he now struggled afresh to get at his vanished quarry. And again the Sergeant had a tussle to hold him.

"I don't know what's got into the big fellow!" exclaimed Mahan to Vivier as the old Frenchman joined the tumultuous group. "He's gone clean daft. He'd of killed that poor woman, if I hadn't--"

"Get him out of here!" ordered the surgeon. "And clear out, yourselves, all of you! This rumpus has probably set a lot of my patients'

temperatures to rocketing. Take the cur out and shoot him!"

"Excuse me, sir," spoke up Mahan, as Vivier stared aghast at the man who commanded Bruce's destruction, "but he's no cur. He's a courier-collie, officially in the service of the United States Government. And he's the best courier-dog in France to-day. This is--"

"I don't care what he is!" raged the surgeon. "He--"

"This is Bruce," continued Mahan, "the dog that saved the 'Here-We-Comes' at Rache, and that steered a detail of us to safety one night in the fog, in the Chateau-Thierry sector. If you order any man of the 'Here-We-Comes' to shoot Bruce, you're liable to have a mutiny on your hands--officer or no officer. But if you wish, sir, I can transmit your order to the K.O. If he endorses it--"

But the surgeon sought, at that moment, to save the remnants of his dignity and of a bad situation by stalking loftily back into the hospital, and leaving Mahan in the middle of his speech.

"Or, sir," the Sergeant grinningly called after him, "you might write to the General Commanding, and tell him you want Bruce shot. The Big Dog always sleeps in the general's own room, when he's off-duty, at Division Headquarters. Maybe the general will O.K. his death-sentence, if you ask him to. He--"

Somewhat quickening his stately stride, the surgeon pa.s.sed out of earshot. At the officers' mess of the "Here-We-Comes," he had often heard Bruce's praises sung. He had never chanced to see the dog until now. But, beneath his armor of dignity, he quaked to think what the results to himself must have been, had he obeyed his first impulse of drawing his pistol and shooting the adored and pricelessly useful collie.

Mahan,--stolidly rejoicing in his victory over the top-lofty potentate whom he disliked,--led the way out of the crowded vestibule into the street. Bruce followed demurely at his heels and Vivier bombarded everybody in sight for information as to what the whole fracas was about.

Bruce was himself again. Now that the detested man in woman's clothes had gone away, there was no sense in continuing to struggle or to waste energy in a show of fury. Nevertheless, in his big heart burned deathless hatred toward the German who had kicked him. And, like an elephant, a collie never forgets.

"But," Vivier was demanding of everybody, "but why should the gentle Bruce have attacked a good nurse? It is not what you call 'make-sense.'

C'est un gentilhomme, ce vieux! He would not attack a woman less still a sister of the Red Cross. He--"

"Of course he wouldn't," glumly a.s.sented the downhearted Mahan. "But he DID. That's the answer. I saw him do it. He knocked her down and--"

"Which nurse was she?" asked a soldier who had come up after the trouble was over.

"A new one here. I don't know her name. She came last week. I saw her when she got here. I was on duty at the K.O.'s office when she reported. She had a letter from some one on the surgeon-general's staff. But why Bruce should have gone for her to-day--or for any woman--is more than I can see. She was scared half to death. It's lucky she heard the surgeon order him shot. She'll suppose he's dead, by now.

And that'll cure her scare. We must try to keep Bruce away from this end of the street till he goes back to headquarters to-morrow."

As a result Bruce was coaxed to Mahan's company-shed and by dint of food-gifts and petting was induced to spend most of the day there.

At sunset Bruce tired of his dull surroundings. Mahan had gone on duty; so had Vivier; so had others of his friends. The dog was bored and lonely. Also he had eaten much. And a walk is good, not only for loneliness, but for settling an overfull stomach. Bruce decided to go for a walk.

Through the irregular street of the village he picked his way, and on toward the open country beyond. A sentry or two snapped fingers of greeting to him as he strolled past them. The folk of the village eyed his bulk and graceful dignity with something like awe.

Beyond the hamlet the ridge of hilltop ran on for perhaps a quarter-mile before dipping into the plain below. At one end of this little plateau a company of infantry was drilling. Bruce recognized Mahan among the marching lines, but he saw his friend was on duty and refrained from going up to him.

Above, the sunset sky was cloudless. Like tiny specks, miles to eastward, a few enemy airships circled above the heap of cl.u.s.tered hills which marked the nearest German position. The torn-up plain, between, seemed barren of life. So, at first, did the farther end of the jutting ridge on which the village was perched. But presently Bruce's idly wandering eye was caught by a flutter of white among some boulders that clumped together on the ridge's brow farthest from the village.
