BULLETIN 1385, U. S. DEPARTMENT OF AGRICULTURE 
The Netherlands does similar work and perhaps even more exten- 
sively. Probably the investigation of poultry diseases from the 
standpoint of service to the poultrymen is better developed in the 
Netherlands than in any other country, not excepting the United 
States. The Government maintains a pathological laboratory and 
serum institute at Rotterdam in which the director, with assistants, 
devotes his entire time to poultry diseases. Sick and diseased poul- 
try from all over the country are continually coming to this labora- 
tory for diagnosis and suggestions for treatment. This service 
is free. 
Italy conducts classes in poultry management at the Royal School 
of Agriculture, adjacent to Koine. Poultry investigations are con-

Scientific work in poultry and eggs conducted in Europe bears 
much less relationship to the practical problems of the producers 
than in this country. The scientist apparently works for the inter- 
ests of pure science without respect to the application of his results 
to practical conditions. In fact, there seems to be but little in 
common between the scientist and the practical man. There is 
greater harmony of interest between the scientist and the practical 
man in England, Denmark, and the Netherlands than in the rest of 
Europe; but, even in these countries, the relation between the scien- 
tist and the producer is much less evident than it is in the United 
States.
