I am an Englishman, of 170 pounds of steam, up to 100 pounds of pressure. I was born in Lancashire, in 1850, and at twenty pounds of steam I was considered to be of 100-horse power. At forty pounds of steam I was increased to 200-horse power; at sixty pounds of steam to 400-horse power; at eighty pounds of steam to 600-horse power; and at 100 pounds of steam to 800-horse power.

I am common in the United States, but not in France. I am soft in Germany, but in Russia I am always kept
