of heating a sufficiently extensive surface to bright redness by a 

 moderate amount of gas ; hence the low efficiency of all gas stoves. 

 Fletcher seeks to recover some portion of the heat carried away by 

 the products of combustion by passing these through a chamber 

 traversed by tubes open above and below ; the air from the room 

 in its passage through these tubes becomes heated, so that the 

 heating is effected by this stove partly by means of hot air and 

 partly by radiant heat ; fresh air may be admitted from outside to 

 the tubes. 



Gas cooking stoves are economical because they need not be 

 used a moment longer than is necessary. In the majority, the gas 

 jets are so arranged as to bake the food ; in a few, however, the 

 cooking may be effected as in the case of an ordinary fire by radi- 

 ated heat : in fact, a joint may be roasted, and there is reason to 

 believe that this is the better method. In all cases, when gas is 

 used for cooking, a regulator should be attached to the meter or 

 stove ; this is not only desirable on the score of economy, but mainly 

 because it is then possible for the cook so to arrange that the stove 

 is heated to practically the same temperature at various times of 

 the day, and day after day, by merely turning on the supply tap to 

 the same extent. Although it is essential when using a gas stove 

 to be more watchful, as the temperature so much depends upon the 

 rate at which the gas is burnt, a far better opportunity of obtaining 

 even results is afforded by a gas stove as compared with a coal fire ; 

 and it is to be hoped that ladies will avail themselves of the 

 opportunity and more fully investigate the subject of cooking, so 

 that sooner or later we may know exactly the limits of temperature 

 within which the various articles of food should be cooked.
