BROILERS AND ROASTERS. ^ 



where. It has sometimes been claimed by manufacturers 

 that certain machines could be run as well in an outbuild- 

 ing as in a cellar, and this of course was a strong point in 

 favor of such machines with those who did not want to 

 put the machine in the house cellar or make a cellar espe- 

 cially for it. The facts about this matter as I have been 

 able to get them from persons who are running machines 

 entirely above ground, as well as from those who have 

 tried machines in cellars and in buildings above ground 

 simultaneously, are these : In a moderate and equable 

 climate the room above ground may give as good results 

 in general and without more labor than the cellar. In any 

 place where considerable and sudden changes of tempera- 

 ture are frequent, the machines above ground require much 

 closer attention and constant watching to guard against 

 variations in the temperature of the egg chamber corre- 

 sponding with the changes taking place outside. 



26. Pipe Brooder Houses. To attempt even a brief 

 description of the many plans of pipe brooder houses that 

 are now in use, and to present even in outline the many 

 theories that have been more or less thoughtfully worked 

 into them, would require a volume several times the size of 

 this devoted exclusively to that one part of our subject. 

 There would, however, be no great advantage in such a 

 presentation of this subject. All the thought and study 

 and experiment of many men, through many years, has 

 made little difference in the houses. I think we may say 

 no essential difference in principal features. They differ 

 most in minor points, and these can be indicated in course 

 of an account of one plan, or as supplementary to it, just 

 as well as by giving full descriptions of many houses,
