been enlarged in various parts of the farm. From nine to 

 ten acres of permanent grass land have been added to our 

 fodder sources. Every field of the farm has been made to 

 contribute, as far as practicable, to that end. A detailed 

 description of the work carried on in the difierent parts of 

 the farm will be found in the accompanying report. 



The buildings for stock feeding have been considerably 

 enlarged for the purpose of inaugurating experiments regard 

 ing the cost of feed for the production of mutton and beef. 

 The general arrangement for serving the feed has been 

 improved with a view to enter, whenever advisable, upon 

 experiments to study the rate of digestibility of fodder plants 

 peculiar to American farm industry. The live stock of the 

 Station consists at present of two horses, six cows, two 

 steers, six sheep and nine pigs. All, with the exception of 

 the horses, serve at present in experiments to ascertain the 

 cost of feed for the production of milk or meat. 



The details of the work carried on in the barn, the field 

 and the laboratory, during the past year, are recorded in the 

 subsequent pages, under the following headings : -
