 MILK TESTER AT PAN-AMERICAN MODEL DAIRY.

As one branch of the Dairy and Live Stock department of the Pan- 

 American Exposition, a so-called "model dairy" wa's planned by Superin- 

 tendent Converse to be installed and operated at an estimated cost of 

 $6,000.00. 



The impression in some way gained pretty wide circulation, in the 

 United States at least, that the model dairy at Buffalo was to be conducted 

 on broad educational lines, demonstrating to the visiting public the most 

 modern and approved methods of handling and feeding dairy cows as well 

 as handling the product; in fact, that it was to be a show dairy more than 

 a contest of the several breeds of cattle invited to participate. However, 

 when it came time to make the final arrangements and rules for the feeding 

 and crediting of products of the several breeds, the show dairy was given 

 secondary consideration in the all-absorbing question of how to properly 

 and fairly handle the feed and product of ten separate breeds of cows in a 

 six months' contest. 



Considering the small sum set aside for constructing, equipping and 

 maintaining such a dairy , it goes without saying that a model dairy which 

 would meet the approval of the advocate of certified milk dairies and ad- 

 mirer of porcelain lined and nickle-plated dairy-rooms would have been 

 an impossibility. If funds had been provided for such a demonstration 

 alone, it would have been of infinitely less value to the thousands of prac- 

 tical dairy farmers who had put before them for study every week (in some 

 one of the several hundred papers publishing them) the weekly records of 

 the fifty cows in the Pan-American dairy test. In addition to the practical 

 results attained through the agricultural press, the dairy barn was every 

 day thronged with curious and interested visitors studying the animals 

 themselves in connection with their records, weekly renewed and hung
