(8) One experiment in conditions governing the vitality of fowls 

 and fertility and hatchability of eggs. 



(9) One investigation on the cause and cure of so-called white 

 diarrhea in chickens. In addition to several experiments which we 

 have conducted with incubators, brooders, methods of feeding, etc., 

 143 persons have co-operated with us in furnishing data giving the 

 results of their experience with mortality in chickens. 



Data has been accumulated for subject matter for eight bulletins. 



During the year, two bulletins have been published : No. 246, on 

 the " Gasoline Heated Colony House for Brooding Chickens," and 

 No. 248, " Handy Poultry Appliances," the editions of which, 

 25,000 of the former and 20,000 of the latter, is practically 

 exhausted. 



The correspondence has steadily increased during the year and 

 now averages fifteen letters daily. There were 3,596 letters written 

 during the year. Correspondence will undoubtedly increase with 

 the publication of each new bulletin and the sending out each year 

 of new classes of students. 



The income from sales and laboratory fees has steadily increased 

 each year as the plant has increased in size and efficiency. We 

 now have on hand 728 mature stock, including fowls and ducks 

 (and 1.227 young stock), making a total of 1,955 l^^ad of poultry, 

 valued at $2,200. This is a marked increase over ]irevious years, 

 both in quantity and quality. 



Recommendations. 



The demand for instruction in Poultry Husbandry and the call 

 for information on important problems yet unsolved, warrants a 

 large increase in facilities for instruction and for investigation. 



At the earliest possible date a farm of not less than forty to fifty 

 acres should be purchased. 



This should be devoted to two specific purposes : first, a plant 

 where all of the investigational work is performed ; second, a dem- 

 onstration poultry farm to be conducted on a substantial commercial 

 basis, where students and visitors can see a poultry farm in actual 

 operation as it should be conducted ; a poultry farm which can 

 be taken as a pattern by our students and others. Such a farm 

 is necessary in connection with an educational institution as an 

 object lesson to carry conviclicMi. 



The commercial plant could be made to jiay a good profit on the 

 investment. On this farm would be reared and kept the stock 

 which would supply the instructional plant, wliieli should always
