"Now we will go and have a look in the yard. Will you come, Cyril?"

"I should like to come," Cyril replied, "but, as I have never been out there before, had you not better make some pretext for me to do so. You might say, in the hearing of the apprentices, 'We may as well take the measurements for that new shed we were talking about, and see how much boarding it will require.' Then you can call to me out from the office to come and help you to measure."

"Then you still think the apprentices are in it?" John Wilkes asked sharply.

"I don't say I think so, John. I have nothing against them. I don't believe they could come down at night without being heard; I feel sure they could not get into the shop without that stiff bolt making a noise. Still, as it is possible they may be concerned in the matter, I think that, now we have it in good train for getting to the bottom of it, it would be well to keep the matter altogether to ourselves."

"Quite right," Captain Dave said approvingly. "When you suspect treachery, don't let a soul think that you have got such a matter in your mind, until you are in a position to take the traitor by the collar and put a pistol to his ear. That idea of yours is a very good one; I will say something about the shed to John this morning, and then when you go down to the counting-house after dinner I will call to you to come out to the yard with us."

After dinner, Captain Dave went with Cyril into the counting-house.

"We had an order in this morning for a set of ship's anchors, and John and I have been in the yard looking them out; we looked over the place pretty sharply, as you may be sure, but as far as we could see the place is as solid as when it was built, fifty years ago, by my father."

The Captain went out into the store, and ten minutes afterwards re-entered the shop and shouted,—

"Come out here, Cyril, and lend a hand. We are going to take those measurements. Bring out your ink-horn, and a bit of paper to put them down as we take them."

The yard was some sixty feet long by twenty-five broad, exclusive of the space occupied by the warehouse. This, as Cyril had observed from the window above, did not extend as far as the back wall; but on walking round there with the two men, he found that the distance was greater than he had expected, and that there was a space of some twenty feet clear.
