The World's Locomotives.

In the beginning of 1890 the total number of the world’s locomotives amounted to 105,000, representing from 5,500,000 to 7,000,000 horse power. Taking the figures as 6,000,000 only, this gives the total horse power of the whole of the steam engines and locomotives on earth as 49,000,000. The horse power of a steam engine may be estimated as equivalent to the power of three horses, and the power of a horse as equivalent to that of seven men.
