"You needn't apologize for feeding me," I replied cheerfully. "I've a lot of lost time to make up in the eating line."

It was a merry meal, that little banquet of ours in the Betty's cabin. The morning's sail had given us a first-rate appetite, and in spite of the somewhat unsettled state of our affairs we were all three in the best of spirits. Indeed, I think the unknown dangers that surrounded us acted as a sort of stimulant to our sense of pleasure. When you are sitting over a powder mine it is best to enjoy every pleasant moment as keenly as possible. You never know when you may get another.

At last I decided that it was time for me to start.

"I tell you what I think I'll do, Tommy," I said. "I'll see if there's any way along outside the sea-wall. I could get right up to the place then without being spotted, if there should happen to be any one there."

Tommy nodded. "That's the idea," he said. "And look here: I brought this along for you. I don't suppose you'll want it, but it's a useful sort of thing to have on the premises."

He pulled out a small pocket revolver, loaded in each chamber, and handed it over to me.

I accepted it rather doubtfully. "Thanks, Tommy," I said, "but I expect I should do a lot more damage with my fists."

"Oh, please take it, Neil," said Joyce simply.

"Very well," I answered, and stuffing it into my side pocket, I buttoned up my coat. "Now, Tommy," I said; "if you'll put me ashore we'll start work."

It was about a hundred yards to the mouth of the creek, and with the tide running hard against us it was quite a stiff little pull. Tommy, however, insisted on taking me the whole way down, just to see whether there was any chance of getting along outside the sea-wall. We landed at the extreme point, and jumping out on to the mud, I picked my way carefully round the corner and stared up the long desolate stretch of river frontage. The tide was still some way out, and although the going was not exactly suited to patent-leather boots, it was evidently quite possible for any one who was not too particular.
