'No; I have not seen a storm rage as long for years as the one that kept us in that shaft. Nor have I had so narrow an escape since I have been connected with it; the rescuers made the mistake of acting as if we had recharged. When we left we had air for three and a half hours, and never expected any delay. Two minutes more would have finished us. The men below had no idea that anything had happened. The mine will be almost absolutely safe when we get down to it the proper way; meanwhile we shall soon have copper enough, and can give up the present working.'
Harry Brand shortly afterwards took his departure.
CHAPTER XIII.
To the Metropolis. Sidonia.
FOR two days our train ran along the main line, stopping only to recharge the accumulators. This takes but a few minutes, and occurs at about the end of each five hundred miles. Grayson and I had many interesting conversations, and I profited not a little by association with a man who knew so much and had so ripe a mind. It appeared as if we could touch upon no topic with which he was not thoroughly acquainted. Though we were travelling underground he could tell me all about the surface above each part. He described it an being generally unequal and cavernous. He said that small plantations were placed on the summits for the purpose of growing wood, and that the slopes were mostly used for fruit growing. Reservoirs occupied all the spaces that could be conveniently dammed, and the plains and valleys were irrigated wherever water could be applied with advantage. Altogether he showed plainly enough that without labor and constant attention the land on this side the ocean would be about as useless as that on the other side before Weston's scheme was worked out. I more and more admire my fellow humans when I see how rich and productive they have made a little third rate and cold planet by their labor alone.
'Metropolitan Central.' As our train slowed down I saw these two words in large letters on a distant wall, not painted nor gilded, but written in light. We had travelled a week and come nearly half way round the planet, Grayson did not want to part with me, and I felt that I had found a second father, so we went together to his house. He promised to introduce me to the Earthborn's Club after dinner, when many of the members would have finished work for the day and would be found there. I had no hesitation in accepting Grayson's hospitality, for he, having the freedom of the planet cannot be put to any expense.
Having performed my ablutions and made a few changes, my first action was a walk through a small part of the museum. I say a small part, for it will take weeks to visit all of it. The first thing to which I gave serious
