Thus the dimensions of the largest glass tanks greatly exceed those of the largest steel furnaces; glass furnaces containing up to 250 tons of molten sible to work glass-tanks continuously for many months together; on the other hand, glass is not readily freed from foreign bodies that may become admixed with it, so that the absence of detachable particles is much more essential in glass than in steel melting.
Rollers up to 5 tons in weight are employed and are now generally driven by power.
Yet tons of caustic soda are fused daily in chemical works in iron pots without thereby suffering contamination, which seems to show that (clean) iron, like gold and silver, is attacked only by the joint action of fused alkali and air, the influence of the latter being of course minimized in large-scale operations.
The output of copper rose from 997 tons in 1911 to 27,462 tons in 1917; it was 22,000 tons in 1919 and 19,000 tons in 1920.

The factory expenses are taken at £30,000 per annum, or £3 per ton on a crop of 10,000 tons (the sugar to cost £8 per ton all told at the factory) - equivalent to £300 per day for the loo working days of crop time.
Here the tropical heat is tempered by constant trade winds, there is perfect immunity from hurricanes, the soil is peculiarly suited for cane-growing, and by the use of specially-prepared fertilizers and an ample supply of water at command for irrigation the land yields from 50 to 90 tons of canes per acre, from which from 12 to 14% of sugar is produced.
By the adoption of this system in one large plantation in the West Indies, crushing upwards of 1200 tons of canes per day, the labour of sixty-four hands was dispensed with, and was thus made available for employment in the fields.
On the other hand, the advocates of admitting the feed into a vacuum pan in many minute streams appeal rather to the ignorant and incompetent sugarboiler than to a man who, knowing his business thoroughly, will boil 150 tons of hot raw sugar in a pan in a few hours, feeding it through a single pipe and valve io in.
There were 173 of these factories working in Cuba in 1908-1909, among which the " Chaparra," in the province of Oriente, turned out upwards of 69,000 tons of sugar in the crop of about 20 weeks, and the " Boston " had an output of about 61,00o tons in the same time.
The average weight per acre was over 252 tons, and the mean percentage of pure sugar in the juice exceeded Isl.

It has been estimated that 500,000 tons of phosphate were obtained in Aruba, 1,000,000 tons from Curacoa since the deposits were discovered in 1870, and Christmas Island in 1907 yielded 290,000 tons.
In 1908 Florida produced 1,673,651 tons of phosphate valued at 11 million dollars.
All the other states together produce less phosphate than Florida, and among them Tennessee takes the first place with an output of 403,180 tons.
The joint production of Tunis and Algeria in 1907 was not less than a million tons.
The production is on the whole diminishing in Belgium (180,000 tons in 1907), but in France it is still large (375,000 tons in 1907).
As much as 200,000 tons of phosphate have been raised in these provinces, but in 1906 the total production of Spain was only 1300 tons.
In 1909 the amount of the hay crop (5,002,000 tons) was greater than that of any other state except Iowa, and its value ($71,028,000) was greater than in any other state.
The total output of the state increased from 651,228 long tons in 1884 to 1,253,393 long tons in 1890, decreased to 179,951 long tons in 1898, again increased to 1,375,020 long tons in 1907, when only three states produced more, and was only 697,473 long tons in 1908 when the state held the same rank as in 1907.
The Western Inland Lock Navigation Company, chartered by the state in 1792, completed three canals within about four years and thereby permitted the continuous passage from Schenectady to Lake Ontario of boats of about 17 tons.
The Erie Canal was begun by the state in 1817 and opened to boats of about 75 tons burden in 1825.
As, however, this decline was accompanied with a considerable decrease in the proportion of the country's exports which passed through the port of New York, interest in the canals revived, and in 1903 the electorate of the state authorized the issue of bonds to the amount of $101,000,000 for the purpose of increasing the capacity of the Erie, the Champlain and the Oswego canals, to make each navigable by barges of 1000 tons burden.

Boats of 350 tons can ascend generally as far as Mi.inden.
The first important coal-mining was near Bellingham Bay, in Whatcom county, where coal was discovered in 1852 and where 5374 tons were mined in 1860.
A small quantity of zinc (7 tons in 1906) is occasionally produced.
Before 1905 the mines were little worked; in that year the output was 118,000 tons, while in 1907 over 500,000 tons were raised.
Other discoveries about Butte followed, and the output of copper increased from I I,01I long tons in 1883 to 129,805 long tons in 1906, more than 99.6% from Silverbow county.
Coal was discovered in Montana before 1880, when 224 tons were mined.
In 1907 the output was 2,016,857 tons, and in 1908 1,920,190 tons.
The output steadily increased until 1895 when it was 1,504,193 short tons; but from then to 1905, when it was 1,643,832 short tons, the quantity varied little from year to year.
