He sat down on a big packing-case, tucked up his legs under him and pulled silently at the glowing Perfecto. Then he began:

"At eleven o'clock in the forenoon," said Tam, settling himself to the agreeable task, "in or about the vicinity of La Bas a solitary airman micht ha' been sighted or viewed, wingin' his way leisurely across the fleckless blue o' the skies. Had ye been near enough ye would have obsairved a smile that played aroond his gay young face. In his blue eyes was a look o' deep thought. Was he thinkin' of home, of his humble cot in the shadow of Ben Lomond? He was not, for he never had a home in the shadow of Ben Lomond. Was he thinkin' sadly of the meanness o' his superior officer who had left one common seegair in his box and had said, 'Tam, go into my quarters and help yourself to the smokes'?"

"Tam, I left twenty," said an indignant voice, "and when I came to look for them they were all gone."

"A've no doot there's a bad character amongst ye," said Tam gravely; "A' only found three, and two of 'em were bad, or it may have been four. No, sir-rs, he was no' thinkin' of airthly things. Suddenly as he zoomed to the heavens there was a loud crack; and lookin' over, the young hero discovered that life was indeed a bed of shrapnel and that more was on its way, for at every point of the compass Archie was belching forth death and destruction"—he paused and rubbed his chin—"Archie A' didn't mind," he said with a little chuckle, "but Archie's little sister, sir-r, she was fierce! She never left me. A' stalled an' looped, A' stood on ma head and sat on ma tail. A' banked to the left and to the right. A' spiraled up and A' nose-dived doon, and she stayed wi' me closer than a sister. For hoors, it seemed almost an etairnity, Tam o' the Scoots hovered with impunity above the inferno—"

"But why, Tam?" asked Blackie. "Was it sheer swank on your part?"

"It was no swank," said Tam quietly. "Listen, Captain Blackie, sir-r; four guns were bangin' and bangin' at me, and one of them was a good one—too good to live. Suppose A' had spotted that one—A' could have dropped and bombed him."

Blackie was frowning.

"I think we'll leave the Archies alone," he said; "you have never shown a disposition to go gunning for Archies before, Tam."

Tam shook his head.

"It is a theery A' have, sir-r," he said; "yon Archie, the new feller, is being tried oot. He is different to the rest. Mr. Austin had him the other night. Mr. Colebeck was nearly brought doon yesterday morn. Every one in the squadron has had a taste of him, and every one in the squadron has been lucky."
