PREFACE 



cessf ul poultry farms ; not that the special poultry farm is 

 by any means a true measure of the poultry industry, for 

 the industry is, and probably always will be, largely a busi- 

 ness for the general farmer, but that the success of special 

 poultry-keeping is a measure of the advance that has been 

 made in the solution of practical poultry problems. 



This book, therefore, has been prepared that it may add 

 to the available poultry literature; not that it may sup- 

 plant other books, nor that it should be the last word on 

 the subject. The author is fully conscious of its imper- 

 fections; but, to every student of poultry culture, and to 

 every poultry farmer, he earnestly hopes that it may bring 

 some helpful message.
