instruments and operator's hands prepared, the scrotal incision is 

 made by grasping both testicles in the left hand and with two bold 

 strokes of the knife cut through skin of scrotum and testicular 

 coverings without hesitation. Expose both testicles to view. The 

 larger the incision the better the results. They should not be less 

 than 3!/o to 4 inches long and about % to 1 inch on each side of 

 the raphe ("median line") and parallel to it (see Fig. 14). 



The testicles are now exposed. Grasp one of them with the left 

 hand, being careful not to touch the cord above where it is to be 

 severed. Place the emasculator on the cord, being careful to see 

 that the crimping side is next to the scrotum. Now lift the testicle 

 upwards at direct right angles to the animal by making from two 

 to three pounds — depending upon size of horse — tension on the 

 cord, at the same time pushing the emasculator well down against 

 the scrotum and at right angles to the cord, after which close 

 the instrument quickly and firmly until the cord and all its cover- 

 ings are severed as close to the scrotum as possible. (See Fig. 15.)
