Tam o' the Scoots. Wallace Edgar

something down," said Blackie, as a flaming German aeroplane shot downward from the clouds. "But I'm afraid it's not Müller this time."

      It was not. Tam returned morose and uncommunicative. His anger was increased when the intercepted wireless came to hand in the evening:

      "Captain Müller shot down his twenty-seventh aeroplane."

      That night, when the mess was sitting around after dinner, Tam appeared with a big armful of cigars.

      "What's the matter with 'em?" asked Blackie in mock alarm.

      "They're a' that Mister Carter bocht," said Tam untruthfully, "an' A' thocht ye'd wish to ha'e a few o' the laddie's seegairs."

      Nobody was deceived. They pooled the cigars for the mess and Tam went back to his quarters lighter of heart. He slept soundly and was wakened an hour before dawn by his batman.

      "'The weary roond, the deely task,'" quoted Tam, taking the steaming mug of tea from his servant's hands. "What likes the mornin', Horace?"

      "Fine, Sergeant—clear sky an' all the stars are out."

      "Fine for them," said Tam sarcastically, "they've nawthin' to do but be oot or in—A've no patience wi' the stars—puir silly bodies winkin' an' blinkin' an' doin' nae guid to mon or beastie—chuck me ma breeches an' let the warm watter rin in the bath."

      In the gray light of dawn the reliefs stood on the ground, waiting for the word "go."

      "A' wonder what ma frien' MacMuller is thinkin' the morn?" asked Tam; "wi' a wan face an' a haggaird een, he'll be takin' a moornfu' farewell o' the Croon Prince Ruppect.

      "'Ye're a brave lad,' says the Croon Prince, 'but maybe Tam's awa'.'

      "'Naw,' says MacMuller, shakin' his heid, 'A've a presentiment that Tam's no' awa'. He'll be oop-stairs waitin' to deal his feelon's-blow. Ech!' says Mister MacMuller, 'for why did I leave ma fine job at the gas-wairks to encoonter the perils an' advairsities of aerial reconnaissance?' he says. 'Well, I'll be gettin' alang, yeer Majesty or Highness—dawn't expect ma till ye see ma.'

      "He moonts his graind machine an' soon the intreepid baird-man is soorin' to the skies. He looks oop—what is that seenister for-rm lairking in the cloods? It is Tam the Comet!"

      "Up, you talkative devil," said Blackie pleasantly.

      Tam rode upward at an angle which sent so great a pressure of air against him that he ached in back and arm and legs to keep his balance. It was as though he were leaning back without support, with great weights piled on his chest. He saw nothing but the pale blue skies and the fleecy trail of high clouds, heard nothing but the numbing, maddening roar of his engines.

      He sang a little song to himself, for despite his discomfort he was happy enough. His eyes were for the engine, his ears for possible eccentricities of running. He was pushing a straight course and knew exactly where he was by a glance at his barometer. At six thousand feet he was behind the British lines at the Bois de Colbert, at seven thousand feet he should be over Nivelle-Ancre and should turn so that he reached his proper altitude at a point one mile behind the fire trenches and somewhere in the region of the Bois de Colbert again.

      The aeronometer marked twelve thousand feet when he leveled the machine and began to take an interest in military affairs. The sky was clear of machines, with the exception of honest British spotters lumbering along like farm laborers to their monotonous toil. A gentlemanly fighting machine was doing "stunts" over by Serray and there was no sign of an enemy. Tam looked down. He saw a world of tiny squares intersected by thin white lines. These were main roads. He saw little dewdrops of water occurring at irregular intervals. They were really respectable-sized lakes.

      Beneath him were two irregular scratches against the dull green-brown of earth that stretched interminably north and south. They ran parallel at irregular distances apart. Sometimes they approached so that it seemed that they touched. In other places they drew apart from one another for no apparent reason and there was quite a respectable distance of ground between them. These were the trench lines, and every now and again on one side or the other a puff of dirty brown smoke would appear and hang like a pall before the breeze sent it streaming slowly backward.

      Sometimes the clouds of smoke would be almost continuous, but these shell-bursts were not confined to the front lines. From where Tam hung he could see billowing smoke clouds appear in every direction. Far behind the enemy's lines at the great road junctions, in the low-roofed billeting villages, on the single-track railways, they came and went.

      The thunder of his engines drowned all sound so he could not hear the never-ceasing booming of the guns, the never-ending crash of exploding shell. Once he saw a heavy German shell in the air—he glimpsed it at that culminating point of its trajectory where the shell begins to lose its initial velocity and turns earthward again. It was a curious experience, which many airmen have had, and quite understandable, since the howitzer shell rises to a tremendous height before it follows the descending curve of its flight.

      He paid a visit to the only cloud that had any pretensions to being a cloud, and found nothing. So he went over the German lines. He passed far behind the fighting front and presently came above a certain confusion of ground which marked an advance depot. He pressed his foot twice on a lever and circled. Looking down he saw two red bursts of flame and a mass of smoke. He did not hear the explosions of the bombs he had loosed, because it was impossible to hear anything but the angry "Whar—r—r—!" of his engines.

      A belligerent is very sensitive over the matter of bombed depots, and Tam, turning homeward, looked for the machines which would assuredly rise to intercept him. Already the Archies were banging away at him, and a fragment of shell had actually struck his fuselage. But he was not bothering about Archies. He did swerve toward a battery skilfully hidden behind a hayrick and drop two hopeful bombs, but he scarcely troubled to make an inspection of the result.

      Then before him appeared his enemy. Tam had the sun at his back and secured a good view of the Müller machine. It was the great white dragon-fly he had seen two days before. Apparently Müller had other business on hand. He was passing across Tam's course diagonally—and he was climbing.

      Tam grinned. He was also pushing upward, for he knew that his enemy, seemingly oblivious to his presence, had sighted him and was getting into position to attack. Tam's engine was running beautifully, he could feel a subtle resolution in the "pull" of it; it almost seemed that this thing of steel was possessed of a soul all its own. He was keeping level with the enemy, on a parallel course which enabled him to keep his eye upon the redoubtable fighter.

      Then, without warning, the German banked over and headed straight for Tam, his machine-gun stuttering. Tam turned to meet him. They were less than half a mile from each other and were drawing together at the rate of two hundred miles an hour. There were, therefore, just ten seconds separating them. What maneuver Müller intended is not clear. He knew—and then he realized in a flash what Tam was after.

      Round he went, rocking like a ship at sea. A bullet struck his wheel and sent the smashed wood flying. He nose-dived for his own lines and Tam glared down after him.

      Müller reached his aerodrome and was laughing quietly when he descended.

      "I met Tam," he said to his chief; "he tried to ram me at sixteen thousand feet—Oh, yes. I came down, but—ich habe das nicht gewollt!—I did not will it!"

      Tam returned to his headquarters full of schemes and bright "thochts."

      "You drove him down?" said the delighted Blackie. "Why, Tam, it's fine! Müller never goes down—you've broken one of his traditions."

      "A' wisht it was ain of his heids," said Tam. "A' thocht for aboot three seconds he was acceptin' the challenge o' the Glasca' Ganymede—A'm no' so sure o' Ganymede; A' got him oot of the sairculatin' library an' he was verra dull except the bit wheer he went oop in the air on the back of an eagle an' dropped his whustle. But MacMuller wasn't so full o' ficht as a' that."

      He walked away, but stopped and came back.

      "A'm a Wee Kirker," he said. "A' remembered it when A' met MacMuller. Though A'm no particular hoo A'm buried, A'm entitled to a Wee Kirk meenister. Mony's the time A've put a penny i'
