I had not much line to gather in, though, before I felt the check again, and a furious tug given so hard that I let the line run, and several yards were drawn through my fingers before I began to wonder where the eel or other fish I had hooked had gone.

“Perhaps there is a passage or drain under the works,” I thought as I dragged at the line, now to feel some answering throbs; but the fish did not run any farther, only remained stationary.

“What a monster!” I cried, as I felt what a tremendous weight there was against me. I drew the line and gained a little, but gave way for fear it should break.

This went on for ten minutes or so. I was in a state of the greatest excitement, for I felt that I had got hold of a monster, and began to despair of dragging it up to where I was. Such a thing seemed impossible, for the line would give way or the hook break from its hold I was sure.

In place of jerking about now, the fish was very still, exercising a kind of inert force against its captor; but I was in momentary expectation of a renewal of the battle, and so powerful did the creature seem, so enormously heavy was it, that I began to regret my success, and to wonder what the consequences would be if I were to get the large eel up there on the floor.

One moment I saw myself flying for my life from a huge writhing open-mouthed creature, and saved by a gallant attack made by Piter, who, hearing the noise, had dashed in open-jawed to seize the fierce monster by the neck; the next I was calling myself a donkey.

“Why, of course!” I cried. “When I hooked it the creature ran in towards me, and has darted in and out of some grating and wound the line tightly there.”

That could not be the case, I felt as I pulled, for though it was evident that the fish had entangled the line, it was in something loose which I got nearly to the surface several times, as I gazed down there in the darkness till all at once, just as I was straining my eyes to make out what it was that was entangled with my hook, the cord snapped, there was a dull plash below me, the water rippled and babbled against the side, and all was still once more.

I stood gazing down for a few minutes, and then a flash of intelligence shot through me, and I darted back, rapidly coiling up my wet line and taking it and my basket up into the office, from whence I came hurrying out, and ready to dash down two steps at a time.

“Why, of course,” I kept on saying to myself; “what stupids!”
