British gallon is 4.54346 litres, and the British bushel is 36.3477
litres. The litre is equal to a cubic decimetre of distilled water at
its maximum density, which will conterpoise a standard kilogramme
in a vacuum.
Our readers will find the following approximate equivalents useful in calculations; they are presented merely as suggestions of
comparative values, and not as absolute equivalents:
25- millimetres = 1 inch.
3 metres = 10 feet.
16 kilometres - 10 miles.
1 hectacre — 2.5 acres.
1 cubic metre = 35 cubic feet.
10 cubic metres = 13 cubic yards.
35 hectolitres — 10 bushels.
1 litre = 1 quart.
1 kilo = 2- pounds.
1 quintal = 2 cwt. [gross].
1 millier or tonne = 1 gross ton nearly.
Production of Pig-Iron in the United States in 1889.
THE Bulletin of the American Iron and Steel Association published on January 22, 1890, detailed statistics of the production
of pig-iron in the United States during the year 1889, an achievement in the collection of statistics which we believe has never been
equalled. The twenty-four States which contributed to the manufacture of pig-iron produced an aggregate of 8,517,068 net tons,
equivalent to 7,604,525 gross tons, against 6,489,738 gross tons in
1888, an increase of over 17 per cent., viz., 1,114,787 gross tons.
This production was fairly distributed throughout the year, and,
in addition, the stocks of pig-iron in makers' hands was considerably less at the close of 1889 than it was at the close of 1888.
Of the total amount of pig-iron produced, 5,952,414 net tons were
made with bituminous coal and coke; 1,575,996 tons were made
