incubator lights were put out, that the men who 

 were operating the three hot air machines admitted 

 that their eggs were ruined, but that no injury was 

 done the eggs in their own machine. As the lights 

 on our machines were never put out by a guard, 

 we never had any complaint or admission of the 

 kind to make, nor did we ever hear of any other 

 lights than the one noted being put out by the 

 guard. 



MARKING EGGS. 



The man who is in the poultry raising business 

 for profit, will use every known means to make it 

 a success. By a few marks upon the eggs he 

 makes it possible to know all about each hatch, 

 the causes of success or failure and the direct 

 means by which to improve.
