temperature rises to loij^ degrees or 102 degrees, and remains more 

 or less stationary at 102 degrees until the end of incubation. 



When turning the eggs by the trayful, says Prof. Wheeler, turn 

 slowly and not by a quick whirl. 



"My only guide in regulating moisture is to feel the air when I 

 open the incubator doors," says James E. Rice. "It should have a 

 warm, humid touch and a live smell." 



A uniform heat, and one that will not bring out the chicks 

 ahead of time, is the most important. William H. Truslow thinks 



102 degrees on a reliable thermometer will give better results than 



103 degrees. 



Prof. William P. Wheeler says that unless the eggs are graded 

 more evenly than seems possible in general practice, a slight per- 

 centage of loss of the fertile eggs is unavoidable where a large num- 

 ber of eggs are hatched in one machine. 



B. Holmes says weak germs in an egg from a hen out of con- 

 dition, account for a part of the deaths in the shell. A hen may be 

 out of condition one day and better the next; what affects one or 

 more hens in a pen, may not affect all alike ; therefore, the eggs 

 from the same pen may vary in vigor from day to day, or week to 

 week. 



William H. Truslow says he fears that none of the manufac- 

 turers of incubators can, as yet, held a candle anywhere near a good 

 sitting hen. But there are so many poor hens that will do every- 

 thing but sit properly, that 1,000 eggs set in machines, even though 

 they do not work quite satisfactorily, will usually give as many 

 chicks as 1,000 eggs under hens, and a machine will sit when you 

 can find no hens. 



Never remove the chicks from the incubator at night — wait un- 

 til the next morning. 



James Rankin says he has kept eggs six weeks (for an experi- 

 ment) and hatched about fifty per cent. It, however, is a poor pol- 

 icy to keep eggs longer than one week for incubation ; the fresher 

 they are the better the hatch and the stronger the chicks. 



In running the machine in a cool room, the moist air in the in- 

 cubator will condense on the glass doors. 



James H. Seeley says eggs for hatching should be kept in a dry 

 place at a temperature of 50 or 60 degrees. 



If possible, eggs of the same age should be set in each ma- 

 chine, as old eggs need more moisture, on account of the air cell 

 being larger. 



Never expose the incubator to sunlight. 



Pure air is necessary in the incubator room. 



Lamp trips are good so long as they work freely, but they are 

 very apt to get out of order. 



Always run the incubator several days before putting in the 

 eggs. Be sure that every part of it is working rightly. 



Never try to run, the incubator in a room that is heated up dur- 

 ing the day, and allowed to cool off at night.
