There are several sets of instru- nents made for the purpose of capon- izing a fowl These diSer principally in the type of instrument used in get ting hold of and removing the testicle. One type is the cannula, a. This con sists of hollow tube, the lower end of which is compressed and closed ex- cept for two small holes through which to run the horse hair or wire compris- ing the other part of the instrument This type is very satisfactory, but re- guires two hands to operate. Another type is the twisting scoop, b. This is spoonlike scoop slotted in the center and mounted upon a slender rod. It Is designed to slip under the testicle, allowing the spermatic cord to pass through the slot. By twisting the cord Is severed. This type has the advan- tage of requiring only one hand to operate, but is more liable to produce slips than the cannula. A third style of instrument, i, is also in the form of spoon or scoop, but instead of be- Ing in one piece has two jaws regu- lated by a slide. The testicle is caught in the scoop with the spermatic cord between the jaws, and by tighten ng the jaws and gently moving the in- strument the cord is severed and the testicle removed. Still another type, not now in common use, is the spoon iorceps. With this the testicle is sim ply grasped with the forceps and de- tached by twisting movement. Here one hand can be used also, but the liability of slips is rather greater than with the other methods.
 K, shows type of forceps, consist Ing of two hinged arms, one of which terminates in broad, flat surface, and the other in an end of similar shape, from which the center has been re- moved. leaving only narrow rim. These two ends are held closely pressed together by means of a rubber band passing across the handles. In use, the ends of the forceps are sepa- rated, the solid one slipped under the testicle and the rim then allowed to settle down over it. The cord is then caught and the testcle can be re- moved. Careless or too rapid use of this instrument is likely to cause slips. A knife for making the incision into the body cavity is of course necessary. Almost any disappointed, thin-bladed knife will answer the purpose well tSee c). Some sort of spreader to spring apart the ribs far enough to allow the instruments to be inserted into the body must be used. A plain spring spreader, as shown at d., or a sliding spreader, e, allowing the pressure to be gauged, will answer the purpose. A sharp-pointed hook, h, for tearing away the thin membranes, and d blunt probe. of which g is one type, for pushing aside the intestines, com plete the necessary equipment. A pair of small tweezers or nippers, f, is also useful in removing any foreign matter from the body.
 Improving Methods of Preparing Wool.
 A few wool growers in the North west this season successfully prepared their wool after the methods employed in Australia and New Zealand. As is we'll known, in those countries fieeces are carefully examined when they are sheared, and the wool classers make sure that only one grade of wool is put into a bale, and that the bales of the same lot are uniform. The fieeces are carefully skirted and each fleece, when it enters the bale, is of even, serviceable quality.
 The Pioneer shed, located near Bit ter Creek, Sweetwater county, Wyo., will place upon the market this year 500,000 pounds of wool prepared under the supervision of men familiar with shed operations in Australia and New Zealand These fieeces were skirted, rolled, classed and baled according to the Australian methods. The young men employed in the work in the wool room came principally froml the Uni versity of Wyoming and from the Rock Springs high school. This represented
