The total passenger mileage for the year was 11,847,785,617, a slight increase over the previous year. The total freight mileage was 76,207,047,298, an increase of nearly 10 per cent over that of the previous year. The gross earnings of the year were $1,051,877,632, and the operating expenses $692,093,971, leaving as the income from operations $359,783,661. The income from other sources was $126,767,064, and the total deductions from income were $384,792,138, leaving as the net income $101,758,587, out of which there was paid as dividends on stock $89,688,204. The magnitude of the railway interests of the country is set forth in the above enormous figures. It is still further emphasized by the fact that nearly three-quarters of a million men are in the employ of this industry. Assuming that each such employé supports two others besides himself, it is seen that the railroad interest supports two and a quarter millions, or more than one thirtieth of the inhabitants of the country.
