1910.] American Method of Developing Agriculture. 53 



in this Journal in July last (p. 328), and a similar, but some- 

 what novel, form of giving instruction has recently been tried 

 in Indiana. 



The train was supplied without charge by the Erie Railway 

 Company for the Agricultural Experiment Station of Purdue 

 University, Lafayette, which provided the lecturers and 

 exhibits. 



The train was composed of three coaches and a double side- 

 door horse and carriage car. Lectures of 45 minutes' duration 

 each were given at the stations where the train stopped. The 

 lectures were given in the coaches, which had been fitted up 

 with charts by the University ; and the horse and carriage car 

 contained three cows for demonstration purposes. 



After a lecture of 30 minutes had been delivered a 15-minute 

 demonstration was given in regard to the cows. When the 

 people had assembled on the platform, one of the doors of the 

 car in which the cows were kept was thrown open, and two 

 Jerseys were shown to the spectators. The general run of 

 the demonstration lecture was as follows : — 



"Here you see two Jersey cows. Can anyone say off-hand 

 which is the better ? The first cow cost about £10 per annum 

 to feed. She produced £11 10s. worth of milk or £11 15s. 

 worth of butter fat, so you had about 355. profit per annum 

 for the pleasure of milking her twice a day. The second cow, 

 another Jersey, is a better producer, and gave £ig worth of 

 milk. This cow also cost £10 per annum to feed, but she 

 showed a much larger profit. We get at the value of these 

 cows by record. Every farmer should keep a record of his 

 cows, the same as every other business man does of his 

 business and manufacturing costs. The record is the only 

 way to get at the value of cows for dairy purposes." 



Pamphlets were then handed round explaining the im- 

 portance of milk records, and the lecturer continued : — 



"There are over 600,000 cows in the State of Indiana. One- 

 third of them are of the same type as the first cow shown, so 

 that about 200,000 cows in this State are producing practically 

 no profit at all. These Jersey cows are more suitable for a 

 district where butter is made. You have the great Chicago 

 market for fresh milk before you, and you should see to it 

 that you get cows that will produce plenty of milk."
