After the lower part of the stump is burned 

 away, the upper part settles into the fire 

 and furnishes fuel to burn out the big 

 roots near the surface. 



The lowest section of the cone, with a 

 diameter of thirty inches at the bottom, 

 is made out of heavier sheet iron, while 

 the two upper cones, which taper to a 

 diameter of eight inches, may be made of 

 ordinary stovepipe sheet iron. 



The whole chimney is about six feet 

 tall, but may be made higher if a stronger 

 draft is desired. 



The chimney conducts the smoke up 

 ward and furnishes draft for the flames 



Burning the Roots of Stumps Out 

 of the Ground 



IN wooded localities, farmers, who wish 

 to remove the timber from their land 

 in order to utilize the ground for raising 

 crops, will appreciate a simple device for 

 burning out the stumps and roots, in- 

 vented by John 

 H. Hempy, of 

 New Hampshire, 

 Ohio. 



The inventor 

 has made ingeni- 

 ous use of the 

 well known fact 

 that draft aids 

 combustion, by 

 constructing a 

 conical chimney 

 of sheet iron in 

 several sections, 

 which is so placed 

 over the ignited 

 stump that a 

 strong draft is 

 created. The air, 

 rushing in from 

 below, by its oxy- 

 gen aids the proc- 

 ess of combustion 

 and keeps the fire 

 burning briskly. 



The water slowly passing around the 

 large heating element in the metal cyl- 

 inder is heated almost instantaneously 



Turn the Switch and You'll Have ■ 

 All the Hot Water You Will Need 



FREDERICK POOLE, of Kansas, has 

 invented a water heater which 

 operates electrically. It is even simpler 

 than the gas heater. 



An ordinary electric high-resistance 

 heating element is placed in a large 

 cylinder, about a foot in diameter. When 

 water from the small pipe main enters so 

 big a chamber, it travels very slowly. 

 Therefore, when the current is turned 

 through the heating element, the heat 

 from its large radiating surface has an 

 opportunity to make the water hot in so 

 short a time that the method might well 

 be classified as instantaneous. 



In any home having electricity, 

 but where, without this attach- 

 ment, it has 

 always 

 been neces- 

 s a r y to 

 light the 

 kitchen 

 range, and 

 then to 

 %\' a i t a n 

 hour or 

 more in or- 

 der to have 

 hot water ; 

 the advan- 

 t a g e s of 

 this quick 

 method of preparing the 

 morning bath, or, in 

 case of emergency, of ob- 

 taining hot water at any 

 hour of the night, will be 

 obvious.
