DISEASES OF CATTLE 157 



spring will be found in the region of the back in the form 

 of small lumps under the skin. 



Symptoms: Warbles are frequently seen under the 

 skin in the region of the back and over the loins, and 

 are very tender to the touch. When they are fully de- 

 veloped they work their way through the skin, which 

 usually occurs in the early part of the summer. Ex- 

 amine your cattle in the winter and spring for the 

 presence of grubs. They can be easily found by run- 

 ning the hand over the , loins, by abrupt swellings or 

 bunches on the skin. Pressure on the swellings will 

 perhaps cause the grubs to pop out. 



Tkeatment: Eemove the grubs by making a small 

 incision with a clean, sharp knife in the center of the 

 swelling. Then press them out and into each cavity 

 from which the grub has been extracted, or squeezed out, 

 should be injected a five per cent solution of Carbolized 

 Sweet Oil to prevent any further development of flies 

 or grubs. Cattle sprayed with fly repellants during the 

 spring and summer are very seldom bothered with war- 

 bles or grubs. However, this is not practical in range 

 cattle; dipping instead should be resorted to-, and it is 

 surprising what results will be derived from fly repel- 

 lants in a year or two. They will practically exterminate 

 the pest, and consequently the cattle are thrifty and look 

 much better. 



WARTS 



Cause: Warts may appear on various parts of the 

 body, and are due to an abnormal growth of cells growing 

 upon the outer surface of healthy skin, or they may grow 

 upon skin that is deprived of the proper blood supply. 



Tkeatment: If the wart is located where there is 

 hair surrounding it, cut away the hair, then wash the 

 wart and surrounding parts with a five per cent solution 

 of Carbolic Acid and clip the wart off with a sharp pair 

 of scissors or knife. After the wart is removed, can-
