Still other ways of holding the fowl in place have been devised, but these are unimportant so long as the fowl is held securely stretched out. DETAILS OF THE OPERATION Having fastened the fowl, be sure that all the instruments are at hand. It is also well, though not necessary, to have ready some absorbent cotton and a dish of water to which have been added a few drops of carbolic acid or some other antiseptic. Having once started, carry the operation through as quickly as possible. Moisten and remove the feathers from a small area over the last two ribs just in Fig. 59. Feathers plucked away to make ready for incision. (Drawn from photograph by Slocum) front of the thigh (Fig. 59). With the left hand slide the skin and flesh down, toward the thigh. Holding it thus, make the incision between the last two ribs (Fig. 60), holding the edge of the knife away from you as you stand back of the fowl. Lengthen the incision in each direction until it is 1 to iH inches long. Now insert the spreader into the incision, thus springing the ribs apart, as shown in figure 61. The intestines will now be visible, covered by a thin membrane called the omentum. Tear apart this membrane with the hook, and the upper testicle, yellow or sometimes rather dark colored and about the size and shape of an ordinary bean, should be visible close up against the backbone. By pushing aside the in- testines this can easily be seen, and the lower one also, in a similar position on the other side of the backbone. Expert operators usually remove both testicles through one incision. This is a desirable prac-
