132 SPECIAL CATTLE THERAPY 



should be cast, unless she happens to be a very gentle 

 one. 



The affected teat is to be washed thoroughly with 

 soap and warm water and then dried and a local anes- 

 thetic used. A milk tube, of the self-retaining variety, 

 and of sufficient length to reach the whole length of 

 the teat, is then inserted. With a small, sharp curette 

 the Avails and edges of the fistulous opening are now 

 thoroughly scarified, and any indurated tissues on the 

 surface edges are removed. When this has been thor- 

 oughly accomplished all hemorrhage, which is some- 

 times considerable, must be controlled by pressure and 

 wiping, before the next step is taken. 



When the hemorrhage has ceased, at least so far 

 that it amounts to only a slight oozing, the wound is 

 given a light application of tincture of iodin with a 

 cotton swab and applicator. 



The last step consists of snugly wrapping the entire 

 teat with layer after layer of gauze strip, interposing 

 between each a coating of pine tar. A two-inch gauze 

 bandage is about right. 



We first apply a coat of pine tar directly on the 

 teat around its entire surface from top to bottom. We 

 then begin bandaging on top of this, and, as the band- 

 age is applied, we apply a coat of the tar after each 

 lap, until about seven* or eight layers of both tar and 

 bandage have been applied. The bandage must be 

 drawn just ''good and snug," not too tight nor too 

 loose. The milk tube is j^et in the duct and allow- 

 ance must be made for it — namely: that the bandage 

 will be ''just snug" Avhen the tube is pulled out of the 

 teat. When seven or eight turns of the gauze bandage 

 have been applied, it is tied, or sewed, to the last turn. 

 Another layer of tar is then applied over all.
