The accompanying cut will give a fair idea '^f its okane's double-valve smokee. As the bellows opens, the air enters through valve No. 1. As the bellows is closed, the air is forced through valve No. 2, through the closed end of the air chamber and through the connecting tube, directly into the fire barrel. As soon as the air in the bellows is exhausted, valve No. 2 closes, thus shutting out smoke and sparks from the bellows, and valve No. 1 opens admit- ting a fresh supply of air. When not in use, valve No. 2 is always closed, and the fire gets air from through the opening near the top or upper end of the air chamber. It will be seen that by this arrangement a continuous passage is formed from the liel- lows to the fire chamber, thus enabling the operator to blow the fire and drive out the smoke with a strong blast; at the same time, smoke, sparks and soot are shut out of the bellows, while the fire has a direct draft when the smoker is not in use. It may be asked why this smoker has not been put upon the market. Mr, Crane says that so many smokers being already on the market, and this one being expensive to make, he doubted if the sales would be snfii- cient to pay for the trouble. As a cold blast smoker, the Clark is objec- tionable on account of its being a '* breech ; The fire in a smoker ought to be at the bottom of the fire box, with the fresh fuel above. With the fire at the top, the danger of blowing out or dropping sparks is greatly increased. The Hill cold blast smo- ker overcomes this objection, as it also does that of being obliged to hold the fire box in such a position, when driving smoke down- â wards, that sparks may drop out. But enough has been said to start the dis- cussion ; now let smoker makers and users criticise and comment, and contribute their views for the July issue. Some Argaments
