Dehoknixg, I. P. Roberts, M. Agr. (pp. ."572-370).— Dehorning has 

 been jmictieed at the station <luring the i)ast or 7 years, and though 

 the operation has for the most part been performed by inexperi- 

 enced persons, no ill effects have followed. Notes and tabulated data 

 are given for five milch cows dehorned November 5, 1891, as compared 

 with seven cows not dehorned. The variations in the yield of milk for 

 the different cows are shown in the following table:

It was found that for the 5 days following the operation as compared 

 with the o days preceding, there was an average daily loss of a little 

 less than one half a pound of milk from the five cows dehorned, while 

 in the same period the seven cows not dehorned gave 0.7 pound jjerday 

 less than in the 5 days preceding the dehorning. 



A pair of patent dehorning clipjters, acting on the ])rincii»le of prun- 

 ing shears, has been successfully used at the station.
