4- APPARATUS FOR COOLING THK AIR—(/vV. y, /o, // and I j) To cool the room, one or other of the following inethorls nia>- be employed r

The first method is the " dinrt " method. It consists in placin- at one or several points of the room, cylinders of-alvanized iron Xo 22, which are filled with ice or a mixtnre of ice and salt.

The.se cylinders shonld be withont bottoms and should rest on slats of 2 inches X 2 inches and about 2 inches apart nailed to the bottom of a water tisht wooden trough lined with jralvanized iron intended to collect the water from the meltino; ice. This trouj^h .should have a slij^ht slope towards one of Its ends in which is the hole, stopped with a wooden pluv, to clean it out. At ordinary times, the water from the meltino- ice will flow off throu-h a i inch iron pipe bent in the form of a siphon, starting- from one of its "extre-mities, pa.ssino: throufrh the floor and communicating with the drain of the factory. This pipe is bent in the form of a siphon to prevent the foul air from the dram K^ettin- in. Where it passes throu-h the floor, il should for the same reason be well packed around with tow or mineral wool.

These c>-linders should be clo.sed aboNc with a -ood wooden coxer They will .spread coolness throuK^h tlie room. This first method should onlv be used in the .sections of the province where the temperature is cool duriiur the summer, in certain parts along the Lower St-Lawrence, for instance and in that case more care than ever should be bestowed on the constructicm of the walls. To increase the refrigerating power of the c\linders, it would be preferable to employ the following indirect cooling method.

This second method consists in placing the cvlinders in a wooden cup-board (fig. 9, 10, II. 12) situated at the bottom of the ventilator shaft The mouths of the cylinders should rise above the upper shelf of the cupboard so that they may be filled with ice without opening the latter They should have no bottom and rest, as in the former case, on slats of c inches apart nailed at the bottom of a water-tight wooden trough lined with -.alvanized iron.

This trough siiould be placed on the floor in tiie bottom of the cupbo-ird with a slight slope towards one of its ends, as in the direct method and ^.e water from the melted ice will flow off through an iron siphon
