"A' doot whither A'll gi'e ye a moostache," said Tam, surveying his handiwork, "it's no necessairy to a fleein'-mon, but it's awfu' temptin' to an airtist." He scratched his head thoughtfully. "Ye should be more tanned, Angus," he said and took up the varnish brush. At last the great work was finished. The dummy was lifelike even outside of the setting which Tam had planned. From the cap (fastened to the plaster head by tacks) to the gloved hands, the figure was all that an officer of the R. F. C. might be, supposing he were pigeon-toed and limp of leg. * * * * * The next morning Tam called on Blackie in his office and asked to be allowed to take certain liberties with his machine, a permission which, when it was explained, was readily granted. He went up in the afternoon and headed straight for the enemy's lines. He was flying at a considerable height, and Captain Müller, who had been on a joy ride to another sector of the line and had descended to his aerodrome, was informed that a very high-flying spotter was treating Archie fire with contempt and had, moreover, dropped random bombs which, by the greatest luck in the world, had blown up a munition reserve. "I'll go up and scare him off," said Captain Müller. He focussed a telescope upon the tiny spotter. "It looks more like a fast scout than a spotter," he said, "yet there are obviously two men in her." He went up in a steep climb, his powerful engines roaring savagely. It took him longer to reach his altitude than he had anticipated. He was still below the alleged spotter with its straw-stuffed observer when Tam dived for him. All that the nursing of a highly trained mechanic could give to an engine, all of precision that a cold blue eye and a steady hand could lend to a machine-gun, all that an unfearing heart could throw into that one wild, superlative fling, Tam gave. The engine pulled to its last ounce, the wings and stays held to the ultimate stress. "Tam!" said Müller to himself and smiled, for he knew that death had come. He fired upward and banked over--then he waved his hand in blind salute, though he had a bullet in his heart and was one with the nothingness about him. Tam swung round and stared fiercely as Müller's machine fell. He saw it strike the earth, crumple and smoke. "Almichty God," said the lips of Tam, "look after that yin! He wis a bonnie fichter an' had a gay hairt, an' he knaws richt weel A' had no malice agin him--Amen!" CHAPTER V ANNIE--THE GUN "A've noticed," said Tam, "a deesposition in writin' classes to omit the necessary bits of scenery that throw up the odious villainy of the factor, or the lonely vairtue of the Mill Girl. A forest maiden wi'oot the forest or a hard-workin' factory lass wi'oot a chimney-stalk, is no more convincin' than a seegair band wi'oot the seegair, or an empty pay envelope." "Why this disquisition on the arts, Tam?" asked Captain Blackie testily.
