PRODUCTION OF GAS. The total quantity of gas sold for lighting and heating, as reported to the Census in 1900 by 877 gas establishments from which returns were received, was 67,093,553,471 cubic feet. The total quantity of gas manufactured by companies as a by-product and disposed of was 1,171,942,697 cubic feet. A combination of this latter quantity with the quantity reported for gas companies shows that, in 1900, the total quantity sold was 68,265,496,168 cubic feet. The price per 1,000 cubic feet varied from $0.832 in Pennsylvania to $4.50 in Nevada. Proximity to the coal and oil-producing districts gives to Pennsylvania the minimum average rate, while distance from source of supplies and limited transportation facilities are accountable for the high price in Nevada. These averages represent the price of all manufactured gas, both fuel and illuminating, as the quantity of each kind was not separately reported; this statement is necessary in order to obviate erroneous deductions. Idaho, Indian Territory, and Oklahoma have no gas plants. The quantity of gas sold in New York city was 18,180,821,125 cubic feet, at an average price of $0.905 per 1,000, or $16,457,822 in the aggregate.

The investment has yielded an income of 40 per cent. In seeking for the cause of the great success attending poultry raising, one must not overlook the great amount of work done by the mechanical incubator, which is not only as fully successful as the hen, but works on a large scale. The Chickens form an essential part of the stock upon many farms. The Twelfth Census shows that there were 5,737.372 farms in the United States in 1900, and it is safe to say that those which did not have chickens among the stock were very few indeed. Census also shows that there were 250,681,593 fowls (chickens, turkeys, geese, and ducks) in the United States. This gives an average of forty-two to every farm. The value of all fowls |
