EAR READERS, I have shown by 

 actual demonstration (as you \vill 

 see by the cuts in this pamphlet) 

 what is possible for persons to do with my 

 incubators and brooders. Also my com- 

 pound, and book on "How to Hatch, 

 Brood, Feed and Prevent Chicks From 

 Dying in the Shell," a long title, but one 

 that covers the question of success. I had 

 this book published after twenty-five years 

 of practical experience with incubators 

 and raising brooder chicks. I made my 

 first incubator from two dry goods boxes 

 with my own hands. I took lessons from a 

 hen by placing a thermometer under her, and watching her 

 movements closely and thus learned the natural laws of incuba-

 from 116 eggs. I had never seen an incubator; did not know 

 the mechanism that was required to construct a hatching ma- 

 chine, but I found that every thing is learned by persistent ef- 

 fort and investigation. I have experimented all these years, 

 making improvements in my incubators and brooders and also 

 my method of operating them, until I have, I think, the best 

 equipments for hatching and brooding little chicks, also the 

 best instructions that were ever placed upon the market; at 

 least I demonstrated the fact. When I advertised, just after 

 my first test, and two weeks before the hatch was due, that I 

 would hatch 2,000 chicks in one day and exceeded my promise 

 by 330, for by actual count I hatched 2,330 chicks, only loosing 

 140 eggs of those left in my incubators after my final test. Iii 

 1905 I hatched 1,087 chicks in one day, only loosing 23 eggs. I
