"She's got rat-tat forward and rat-tat aft, surface speed rat-tat-tat knots, submerged rat-tat-tat, and then best of all she's rattle-tattle-tattle. Yes, hammers are a bit noisy! This way. A destroyer yonder—new class—rat-tat feet longer than ordinary. We expect her to do rat-tat-tat knots and she'll mount rat-tat guns. There are two of them in the basin yonder having their engines fitted, turbines to give rat-tat-tat horse power. But come on, we'd better be going or we shall lose the others of your party."

"I should like to stay here a week," said I, tripping over a steel hawser.

"Say a month," he added, steadying me deftly. "You might begin to see all we've been doing in a month. We've built twenty-nine ships of different classes since the war began in this one yard, and we're going on building till the war's over—and after that too. And this place is only one of many. Which reminds me you're to go to another yard this afternoon—we'd better hurry after the rest of your party or they'll be waiting for you."

"I'm afraid they generally are!" I sighed, as I turned and followed my conductor through yawning doorways (built to admit a giant, it seemed) into vast workshops whose lofty roofs were lost in haze. Here I saw huge turbines and engines of monstrous shape in course of construction; I beheld mighty propellers, with boilers and furnaces big as houses, whose proportions were eloquent of the colossal ships that were to be. But here indeed, all things were on a gigantic scale; ponderous lathes were turning, mighty planing machines swung unceasing back and forth, while other monsters bored and cut through steel plate as it had been so much cardboard.

"Good machines, these!" said my companion, patting one of these monsters with familiar hand, "all made in Britain!"

"Like the men!" I suggested.

"The men," said he, "Humph! They haven't been giving much trouble lately—touch wood!"

"Perhaps they know Britain just now needs every man that is a man," I suggested, "and someone has said that a man can fight as hard at home here with a hammer as in France with a rifle."

"Well, there's a lot of fighting going on here," nodded my companion, "we're fighting night and day and we're fighting damned hard. And now we'd better hurry, your party will be cursing you in chorus."
