Steam Engines within the Borough of Birmingham; By a report made to the Birmingham Philosophical Institution, October, 1836, it appears that 169 steam-engines had been erected from 1780 to that period, of which 17 had been erected in 1834, and 22 in 1835. T h e total horse power was equal to 2700 horses. W i t h i n the same period engines equal to 162 horses' power had become void, or removed. Of those erected and estimated in horse power~ 275 were used for grinding flour; 177o for working metals; 279 foe p u m p i n g water; 87 for glass grinding; 97 for w o r k i n g wood; 44 for paper m a k i n g and g l a z i n g ; S 7 for grinding clay; 6l tbr g r i n d i n g c o l o u r s and chemicals; and 50 for sundry purposes. The estimated consumption of coals is 216 tons per clay; estimated number of persons employed 4000 males, and 13o9 females; and the estimated amount of power hired out~ equal to 450 horses. These estimates are confined to engines within the borough, and, of tours% do not include the great Soho w o r k s o [ Bolton and W a t t . O f the 1770 horse power employed in working metals, it is computed that 162 is used by iron founders, first applied in 1788; 570 in rolling copper, brass, and other metals, first applied in 1790; 150 in d r a w i n g wire, first applied in 1808; 201 in iron forges, and wrought iron mills, first applied in 1810; 74 in nail cutting, first applied in 1813; 104, in screw making, first applied in 1819; and 34, in d r a w i n g metal tubes~ first applied in 1822.--Railway Mug. ibid.
Preservation of IFbod.from Decag. The wood which is used in the salt mines of Hallein, in Germany, is preserved from decay by being saturated in strong brine. T h i s discovery was made by observing, that the timber which supports the ceiling of the galleries~ upon being exposed to the action of the salt earth, became harder and harder, and scarcely ever after liable to decay. F r o m this fact it is supposed that the bichloride of sodium is as efficacious in preservin~ vegetable matter from the destroying energies of the dry-rot, as the bichloride oJ mereur.t]. Certain it is, that the former plan is preferable, to the latter, so far as it is free from the injurious powers which the mercury presents to the workman, when the article which is so prepared is used in manufactories. T h e former is well worthy of trial, and if found to possess the qualities which it is presumed it contains, its economy and simplicity will place it within the reach o f e v e r y individual. Ib~.
