The car jerked out from behind the wagon, dodged into a gap in the reverse traffic, swooped past, and fled squattering down the wet road. “That’s the factory, over there,” said the engineer, pointing, “and that chimney-stack beside it is the Blank Tobacco Factory. They’re doing shells there now.” I expressed some wonder that tobacco manufacture could by any wizardry be converted to shell-making. “Bless you,” the engineer chuckled, “that’s nothing. I can show you queerer changes than that. You see, our great trouble is to get machines enough and men enough to handle ’em. Shows like motor works and boilermakers were dead easy and obvious, and they were scooped in the first snap. Then later--quick, look down this lane--at the end!” The car swooped past, and I had one glimpse, as the lane-entrance opened and shut to our passing, of a dingy, grey vista gleaming with wet puddles and with a couple of lorries blocking the far end. “That,” said the engineer, “is the X Y Z Gramophone works. They’re shell-fuses now.” And so as the car buzzed fiercely down straight stretches, or banked steeply and swung skidding and lurching round greasy corners, or checked sharply and crawled hooting hoarsely and impatiently at impeding carts, the engineer discoursed at length on the conversion of this manufactory or that to munitions, and pointed out a late magneto-maker’s, or a piano factory, or a coach-builder’s, describing their past operations and summing up their conversion with “Now they’re pineapple bombs,” or “They’re rifle-stocks,” or “They’re aeroplane frames.” I asked him if these firms volunteered for munition work. “Some of them,” he said; “but others never dreamed there was any war work they could adapt themselves to.” I thought of the tobacco factory and concluded it was small wonder some didn’t dream of it. “But I will say,” went on the engineer, “as a rule they only want showing, or a hint of a showing, and they get as keen as mustard on it. There was the Rollero Duplicator now. You know what a duplicator is? Thing for printing copies off a typed stencil sheet. Well, they turned over to----” and away he went on another magic-wand conversion tale.
