"What are you going to do with all that money?" asked Steve.
"I think I shall buy some of the company's stock," answered Jarvis.
"Not a half bad idea. That is what I am going to do when I get money enough. As it is, I am sending home most of what I earn. But the money is in good hands," he smiled.
"Mine's in the bank. I am getting four per cent. interest on it, but I haven't got to where I can live on the interest I receive from it. I was figuring the other night, and at the present rate it will be twenty years before I shall be able to live on my income—my interest, I mean."
"Well, I don't want to live on my income. I want to be up and doing something as long as I've got a kick left in me. Cheer up, Bob, you may be a millionaire yet."
"Yes; when I have long, yellow whiskers, maybe," laughed Jarvis.
In the course of two months the new system was working to the satisfaction of everyone. Already it was being applied to the other mines belonging to the company, and even at that early day it was apparent that the Rush Gravity System, as it was called, was destined to prove a great saving to the company. The name, too, was considered unusually appropriate.
One day, a few months later, as Steve was on his rounds, he caught sight of a man in miner's costume who instantly attracted his attention. The man was rather tall and wore a full beard. Rush stopped and gazed after the fellow until he passed out of sight.
"I wonder who he is?" muttered Steve. "There is something about him—about the way he folded his hand over his mouth, that is unpleasantly familiar to me."
On the day following, while Steve was chatting with one of the shift bosses on the twelfth level, he saw the fellow again.
