Tam nodded gravely.

For the first time since he had been a soldier he had a horrid feeling of chagrin, of disappointment, of something that rebuffed and hurt.

"A' see, sir-r," he said, "'tis no' ma wish to put mesel' forward, an' if A've been a wee bit free wi' the young laddies there was no disrespect in it. A' know ma place an' A'm no' ashamed o' it. There's a shipyard on the Clyde that's got ma name on its books as a fitter—that's ma job an' A'm proud o' it. If ye're thinkin', Captain Blackie, sir-r, that ma heid got big—"

"No, no, Tam," said Blackie hastily, "I'm just telling you—so that you'll understand things when they happen."

Tam saluted and walked away.

He passed Brandspeth and Walker-Giddons and responded to their flippant greetings with as stiff a salute as he was capable of offering. They stared after him in amazement.

"What's the matter with Tam?" they demanded simultaneously, one of the other.

Tam reached his room, closed and locked the door and sat down to unravel a confused situation.

He had grown up with the squadron and had insensibly drifted into a relationship which had no counterpart in any other branch of the service. He was "Tam," unique and indefinable. He had few intimates of his own rank, and little association with his juniors. The mechanics treated him as being in a class apart and respected him since the day when, to the prejudice of good order and military discipline, he had followed a homesick boy who had deserted, found him and hammered him until nostalgia would have been a welcome relief. All deserters are shot, and the youth having at first decided that death was preferable to a repetition of the thrashing he had received, changed his mind and was tearfully grateful.

Sitting on his bed, his head between his hands, pondering this remarkable change which had come to the attitude of his officers and friends, Tam was sensible (to his astonishment) of the extraordinary development his mentality had undergone. He had come to the army resentfully, a rabid socialist with a keen contempt for "the upper classes" which he had never concealed. The upper classes were people who wore high white collars, turned up the ends of their trousers and affected a monocle. They spoke a kind of drawling English and said, "By gad, dear old top—what perfectly beastly weathah!"
