The. Normal Dairy. 151 



others again, however, on motives far less meriting 

 of imitation. I always feel a genuine pity for the 

 possessor of a very large barn, a few of which I have 

 seen, and seen photographs and descriptions of many 

 more, particularly located in this country ; they are, 

 in most cases, very creditable testimonials to the de- 

 signing carpenter's skill, and pretty board and shingle 

 monuments to the owner's length of purse, but as for 

 their usefulness and merit for an establishment pro- 

 ducing infants' milk after the methods herein de- 

 scribed and under the supervision of or under contract 

 with a medical board, they should be entirely con- 

 demned. The normal dairy must not only be able to 

 supply the requisite infants' milk, it should also be 

 regulated in a manner to offer the greatest possible 

 security for maintaining this supply continuously, 

 because a sudden falling off from it might mean in- 

 terrupted development and serious inconvenience to 

 many, and, perhaps, death to some infants. This se- 

 curity is not found in the large barns or stables, 

 where a disaster may sweep off the entire productive 

 force in a few hours, or where an infectious disease 

 brought in by one animal may— while in its latent 

 period and, therefore, undetected— spread and infect 

 every animal in the whole herd. Therefore, when 

 there is a chance to do so, it is advisable to keep the 

 cows in separate barns, none to exceed thirty head. 

 Newly bought animals, if not coining from stables in 

 close proximity to the farm and from herds notori- 

 ously free from all disease, should be kept confined
