After some time, I slipped down the bank again, and saw that the waters were lowering considerably. I hurried back to my companions and told them that now I could swim to the ladders and tell our rescuers in what part of the mine we had taken refuge. The professor forbade me to go, but I insisted.

"Go on, Remi, and I'll give you my watch," cried Uncle Gaspard.

The professor thought for a moment, then took my hand.

"Do as you think, boy," he said; "you have a heart. I think that you are attempting the impossible, but it is not the first time that what was thought impossible has been successful. Kiss us, boy."

I kissed the professor and Uncle Gaspard and then, having thrown off my clothes, I went into the water.

"You keep shouting all the while," I said, before taking the plunge; "your voices will guide me."

I wondered if the space under the roof of the gallery was big enough for me to move freely. That was the question. After some strokes I found that I could swim if I went gently. I knew that there was a meeting of galleries not far away, but I had to be cautious, for if I made a mistake in the course I should lose my way. The roof and the walls of the gallery were not enough to guide me; on the ground there was a surer guide, the rails. If I followed them I should be sure to find the ladders. From time to time I let my feet go down and, having touched the iron rails, I rose up again, gently. With the voices of my companions behind me and the rails under my feet, I was not lost. As the voices became less distinct, the noise of the pumps increased. I was advancing. Thank God, I should soon see the light of day!

Going straight down the middle of the gallery, I had only to turn to the right to touch the rail. I went on a little farther, then dived again to touch the rail. It was not there! I went from side to side of the gallery, but there was no rail!

I had made a mistake.

The voices of my companions only reached me in the faintest murmur. I took in a deep breath, then plunged again but with no more success. There were no rails!
