average skim-milk calf that is raised on the farm. Although not 

 fat, they were in a thrifty, healthy condition. 



Our experience given in connection with the experience of 

 men in cheese districts indicates that if we will take the pains 

 of compounding other foods to be used in connection with whey, 

 and carefully watch the calves, it is possible to raise very fair 

 animals with whey as a substitute for milk. 



Feeding Hay Tea. 



To further solve some of the calf problems in the cheese 

 districts and in localities where milk is used for human consump- 

 tion, an experiment was inaugurated to feed calves hay tea. 

 Two kinds of hay were used. First, mixed hay, which con- 

 sisted largely of orchard grass, English blue grass, and a little 

 red clover ; second, alfalfa hay. 



In test 1, the grain ration was first figured out for ground 

 Kafir corn one part, oil meal one part, middlings one part, and 

 soy bean meal one part. The above ration was soon found to 

 be too loosening, and the grain was changed to equal parts of 

 ground Kafir corn and middlings. Three-fourths of a pound of 

 oil-meal was made into a jelly and fed to the hay tea lot daily. 

 As the calves were still subject to scours, the middlings were 

 scalded and fed in with the hay tea. It was found that a tew 

 of the calves would not drink the tea unless there was some 

 skim-milk added to it. (See figs. 5 and 6.) 



In making the tea a large skim-milk vat was used, and under 

 this was constructed a fireplace. The hay was placed in the 

 bottom of this tank and sufficient water added to completely 

 cover it, and after being allowed to soak for a short time the fire 

 was started, the tank covered, and the hay kept in boiling water 

 from one to two hours, after which the hay was placed on a 

 draining board and the tea allowed to drain back into the tank. 

 After all the hay was taken out of the tank the tea was concen- 

 trated by further boiling. We found that it required twelve and
