Mr. J. Demorest of 375 Broadway, introduced his new patent 

 portable Magic Summer stove, and put it in operatiou, A hollow 

 metal ring containing a quart of alcohol, supports above it entirely 

 distinct from it, a series of circular tin ovens. At the bottom is 

 a small metal covered cup whose sides are perforated in many 

 places. A small pipe from the alcohol below is introduced to the 

 bottom of this cup, the stream regulated or shut off at pleasure by 

 acock. The cup contains a quantity of fine wire so closely pressed 

 together as to resemble the sponge. A semicircle of metal pro- 

 vided with similar wire sponge, being first saturated with alcohol 

 (having a stout wire handle to it) is lighted by a match, then ap- 

 plied around the bottom of the cup, this heat soon causes the alco- 

 hol to fill the sponge in the cup, which now burns the gas of the 

 alcohol, producing neither smoke, soot or smell, nor does any very 

 sensible heat radiate from its outside, while a pure and strong 

 heat exists within. Sad iron heating, steak cooking, bread baking, 

 water boiling, all proceed at once in the ovens over oven. The 

 cost of boiling one gallon of water is proved to be but one cent. 

 The circular reservoir of alcohol under all is so entirely separate 

 that it receives no heat during the cooking, and cannot explode. 

 A small stove costs six dollars — large one twelve dollars. De- 

 morest's object is to produce neat, perfect cooking on one's table 

 in summer, and when fuel and cooks are w^anting. Common gas 

 of our streets will answer as well as alcohol.
