BUSINESS POULTRY FARMING. 255 



ers are used, the feed droppers, whether the latter are 

 shelves or cylinders, will always speak for themselves 

 and show whether they have been charged at the proper 

 time and with the proper quantity, the orders being to 

 do everything by rule, of course. The sound of the call 

 bells, supposing that these are operated by employes and 

 not by clockwork, will show what is going on at all 

 times during the day, so that efficiency of the hired help 

 is compelled. This is an advantage not to be despised, 

 though an incidental one not considered when, for other 

 purposes, poultry machinery was originally planned. 



While the use of the Exerciser is as efficacious in giv- 

 ing vitality to eggs designed for hatching as in rearing 

 chicks in brooders, its effects are more palpable and 

 more quickly discovered in the latter case. Divide fifty 

 chicks four days old impartially into two groups of 

 twenty-five each. Put one group into a brooder without 

 the Exerciser and the other group into a brooder exactly 

 the same in all respects, excepting that the latter has 

 the Exerciser attached ; treat both groups scrupu- 

 lously alike as regards sun, air, feeding, watering and 

 everything else down to the smallest details, and then 

 compare the two groups every week till two, three, 

 four weeks have elapsed. The contrast will be simply 

 marvelous. A great deal of exercise, not merely a little, 

 is just what artificially reared chickens need. It goes 

 right to the spot. Hitherto the brooder chicks of the 

 whole United States have not been allowed, one case in 

 fifty, a full plenty of exercise, in winter especially. 

 There is, to many persons, a fascination about artificial 

 hatching and rearing, besides the expectations of pecu- 

 niary gains ; so that thousands on thousands of dollars 

 are invested in incubators, with an enormous amount of 

 chagrin and disappointment as the almost invariable 

 result. Lest the writer should appear to exaggerate on 

 this point let an impartial and competent witness, Mr.
