&eod nnd Cheap Incnbators. — For the benefit of tbose who desire to 

 experience some of the pleasures and profits of artificial incubation, we here 

 give a model of a very simple and reliable incubator, with directions for 

 making the same. 



Have a pine case made somewhat like a common washstand (see Fig. 2) 



without the inside divisions. 



About a foot from the floor of this 

 case, place brackets like those in Fig- 

 1, and on a level with these screw a 

 ong cleat across the back of the 

 case inside. These are to support the 

 tank. 



The tank should be made of gal- 

 vanized iron, three inches deep and 

 otherwise proportioned to fit exactly 

 within the case and rest upon the 

 brackets and cleat. The tank should 

 have a top or cover soldered on when 

 it is made. At the top of this tank in 

 the center should be a hole an inch in 

 diameter with a rim two inches high, and at the bottom, toward one end, a 

 faucet for drawing oflf the water. When the tank is set in the case fiU up all 

 the chinks and cracks between the edges of the tank and the case with plas- 

 ter Paris to keep all fumes of the lamp from the eggs. 



Fill the tank at least two inches deep with boiling water. 

 To find when the right depth is reqnired, gauge the water with a small 

 stick. Over the top of the tank spread fine gravel a quarter of an inch thick; 



over this lav a coarse cot- 

 ton cloth. Place the eggs 

 on the cloth, and set a kero- 

 sene safety-lamp under the 

 center of the tank. 



The door of the lamp- 

 closet must have four holes 

 for ventilation, otherwise 

 the lamp will not bum. 

 The lamf»-cloeet is the 

 space within the incubator 

 uder the tank. Turn the 

 :^'gs carefully every morn- 

 ing and evening, and after 

 turning sprinkle them with 

 quite warm water. Two 

 thermometers should be 

 kept in the incubator, one 

 ■half way between the center and each end; the average heat should be 105 

 degrees. 



If the eggs do not warm up well, lay a piece of coarse carpet over them. 

 If they are too warm, take out the lamp and open the cover for a few min- 

 utes, but do not let the eggs get chilled. If they should happen to get down 

 to 98 degrees, and up to a 108 degrees, you need not think the eggs ar« 

 spoiled. They will stand such a variation once in a while; but of course a 

 oniform temperature of 105 degrees will secure more chickeai, and they wW
