feeds as clover, alfalfa, peas and oats, barnyard millet and corn 

 fodder. 



The manure is remo\"ed twice daily and the cows carded and 

 brushed once a day. Once during the year the barn is thoroughly 

 brushed out and then sprayed with warm water to which is added as 

 much cresol as it will take up (few per cent)*. Stalls and 

 gutters are sprayed at more frequent intervals. Sawdust or baled 

 shavings are used as bedding in sufficient amounts to keep the 

 animals clean. The barn wings in which the animals are housed are 

 heated in winter to a temperature of 50 degrees by steam from the 

 college central heating plant. The barn is in a very exposed place 

 and if this were not done our opportunity for experimentation would 

 be seriously interfered with. Care is taken to keep the barn well 

 ventilated by means of windows, some of which are made to open at 

 the top and bottom and others are hinged at the bottom to open in- 

 ward. (Sherringham valve). 



KEEPING RECORDS. 



The grain and hay are weighed out daily and the weights recorded 

 on prepared blanks. The milk produced at each milking is also 

 weighed on a Chatillon spring balance and the result immediately set 

 down on a record blank. During parts of the year composite samples 

 of each cow's milk are made weekly, and when the animals are not 

 used in an experiment a five-day composite sample is taken monthly ; 

 all samples are tested for fat and solids. 



It will thus be seen that very complete records have been kept of 

 the food consumed and the milk produced. No effort has been made 

 to record the cost of caring for the animals and their product. 



*Sulpho-naphthol is also satisfactory.
