"Steam for full speed" was signalled from "No. 1", and down below dived Mr. Chapman, our engineer, to superintend things in the stokehold.

"They have three hours' start," said Mr. Parker to the Sub, "and it will be a very long stern chase."

"What have we to do if we catch them?" he asked.

"Search them," replied Mr. Parker.

"But what if they won't let us?"

"Search them," replied Mr. Parker, with a queer twinkle in his eye, and then I knew that there might be a fight. It gave me a funny feeling in my stomach, but I knew I was jolly lucky to get the chance and so ought to feel glad, and I really think I did.

We were all going it now with a vengeance. The smoke from "No. 1" and "No. 2" nearly blinded us, and we were shaking and throbbing as the hum of the engines gradually rose, our bows coming out of the water, and our stern squatting down in a mass of foam as we rushed into the wake of the others ahead of us.

I had never been so fast in my life, and was holding on to the bridge rails to avoid being blown away.

We went on like this for hours, and I felt too excited to go down below and get anything to eat. That shows what a ripping thing it is to be rushing along in a destroyer with an enemy ahead.

Presently we formed line abreast, "No. 2" on the starboard and we on the port side of "No. 1", about three miles away from each other, so as to cover more ground.
