Manufactured Ice In Augusta

The Arctic Ice Company are now turning out between ten and twelve thousand ponnds of ice per day, whicli tl y are imder contract to deliver at half a cent a pound. The prooess employed by the company is said to be the clieapest known to scicnce at the present day. The coa of manufacturmg ice here is only eighty-five cents a ton, or about four cents and a quarter a hnndred ponnds. As it ia sold in bullí at ten dollars a ton the margin of protit is nine dollars and fifteen cents on each two thousiind oounds. This is ahead of California gold mining The ice comes out in huge oblong blocks, thirty-tvvo inchos in lenth and twclve inches square. There is spane ín the freezing ctiest (so to speak) for fonr hundred and eighty of these blocks, amounting in weight to thirty thonsand pounda. As it requires sevnty-t.wo hours, however, from the time the vrater 3 poured into the cans nntil it is torneé out aain in solid form, only one-third of the quantity is prortnced dnily. It is the intention of the company to doublé the capacity of the works in a very short 1ime. The blocks in the nevv'chest will be only six inches thiok, and as thyy will freeze much more rapidly than those of doublé the thickness the daily produotion will be correspondingly great. Tbe process by which the freezing is accmnplishod reqnires about fifty ponnda of liqnid aiumonia to be stored in a very strong iron cylinder, and this ia oonnocted with a coil of pipes immersed in a tank of strong brine; into this brine galvanized iron cans holding pure water are placed, and these cans are of the size of the blocks of ice which are formed. The liquid ammonia is allovyed to iiow tiirough these coils, and it gradually becomes frasftV-is, and in beeoming so abstracts from the water so much heat that it speedily freezes. A powerful steara pump f orces the gaseous ammonia back. into the iron cylinder again, thus liberating great heat, which is disposed of by cold water dropping npon the coils of pipes through which the ammonia passes on its way to the condenser. The process is a continuous one, and if the pumps and coils do not leak there is no loss, and the operations may go on so long as the
