BOON TO ALL MANKIND AN INVENTION THAT APPEALS TO
 RICH AND POOR ALIKE.

Every One His Own Iceman-Carbon Di- oxide In Pipes to supplant Cakes of Con- geaied water-CooI Air For sickrooms. All by Turning "A Tap.
 Every man his own iceman" is the watehword of the future.
 A company has been formed to send coolness around i'll pipes, so that man l can turn q tap in his own house and produce a temperature of 100 degrees be- low zero as easy as wink
 This scheme simply is the well known plan of icemaking by the liquefaction and subsequent re-evaporation of gases, except that the gas is carbon dioxide in stead of ammonia, and that it is convey ed around town ill pipes i'll liquid form and applied to anything that is to be cooled or frozen. The raw materials used are soft coal and limestone The products arc carbon dioxide. commer- | cial lime, carbonate of ammonia and coal tar. It is by producing the last three | together with the dioxide that the d. oxide itself is made cheap enough for general use. The coal is supplied to re- torts and subjected to destructive distil- lation in nearly the same manner as in ordinary gas works, the tar and am moniaeal liquor being separated, the former being sold in that state and the latter distilled and converted into car bonate of ammonia, packed and sold. The coke is converted into semiwater gas, which is used to calcine the lime stone. The dioxide is cooled, purified. compressed and Hquifled in the same way as ill other manufactories and then conveyed by it's own pressure through distributing pipes or sold i'll vessels, as may be preferred. One good ton of soft coal and 3 1a tons of limestone, it is said, will produce 8,500 pounds of lime, | 5000 pounds of carbon dioxide, 2 gal Ions of coal tar and 50 pounds of car l bonate of ammonia.
 The prospects of comfort, cleanliness and economy held out by the company are enough to produce the most delight full eommotion i'll the breasts of house keepers. Of course the first point to which every one will want the dioxids conveyed will be his refrigerator. Ths days when the refrigerator must be filled 1 with blocks of ice as heavy as stone and full of bacteria from country swamps are nearly over In place of this it will have few innocent looking iron pipes around the sides Mary will turn small tap, the dioxide will rush through the pipes with noise like steam, the pipes will become coated with ice, and everything in tho refrigerator would be frozen solid if 1t were not for single device at- tached to the pipes. This is nothing less than thermostat, which regulates tho cold This Is adjusted to any degree of frigidity desired, and the moment that 1 limit is reached tho dioxide is automat. ieally checked.
 Ice cream is what the dioxide particu- larly delights in. The freezer is enoir- eled with coil of pipe, and when the dioxide rushes through that coil the cream congoals before one can count tep that is, it would if desired, but it is necessary to stir the cream as it freezes, and this, too, is done by the dioxide, for the waste of the gas Is turned into an engine, the engine works crank, and the crank turns the freezer and stirs l the cream. This invention also furnishes ice water without ice. A great many people would rather drink warm water than water into which ice of unknown he i:,, only to set his drinking water in tho refrigerator and Do sure to fix the thermostat right, so that it will not come out chunk of ice
 The company is not quite ready yet to guarantee that a customer can cool his parlor or bedroom with a jet of diox- idle, and yet 1t does not hesitate to say that in cases of illness it may be the means of alleyiating the patients sui ferings and sometimes saving his lifa A coil of pipe may be arranged ill mar l TOW space between wall and,a screen, and draft at once will becreated which will lower the temperature Of the room. In many cases a coil under the mattress will cool the bed and keep patient in comfort who might otherwise die of the heat. Tho device, therefore, is certain l to become, at some time or other, one of the best appliances ill we'll regulated hospitals.
 From these solemn uses the dioxide may hS hAuhCh tO ObHoISs WnlCn hIS enough, on the first flush, to cause smile. For instance, it will furnish ab- soluto security against the ravages of moths What people need who have costly furs to preserve through tho sum- mer is not eamphor and pepper, but dioxide. They should pack their things in trunk and then spray them with this gas. It is heavier than common air, and when 1t is once in tho trunk and tho trunk is shut it will stay there for ever. The moths will stay thore also, but they will be dead, for no moth can live in this gas.
 Finally every customer for dioxide becomes his own tireman If he comes home in tho evoning and finds his house on fire, he will not run through the street screaming fire and turn on an alarm. IIo simply will turn tho dioxide 4l \. Al n
