REMEDIES AND MEANS OF PREVENTION 327 



feet high in the air when walking, grate their teeth, and froth at 

 the mouth. This is followed by convulsions and, finally, death 

 within six or eight days after the appearance of the first symptoms. 



The above symptoms are sometimes wrongly ascribed to the 

 attacks of worms which cause the sickness known as "gid," or 

 "turn sick." The presence of the bot-fly, however, does not cause 

 the animal to turn in a circle, as in the case of "turn sick." The 

 presence of the bot, too, nearly always causes nasal discharges 

 and snorting, which symptoms are absent in a case of "gid." 



Remedies and Means of Prevention. In the case of common 

 stock destined for the market, a very general and serious attack 

 can perhaps best be met by sending the sheep to the slaughter- 

 house. On the other hand, there are a few remedies or methods 

 of preventing an attack or of relieving the sufferers. If the bots 

 have penetrated into the frontal sinuses, it is apparent that it 

 must be very difficult, if not impossible, to reach them. Certainly 

 one should never use a wire, nor any compound which would injure 

 or cause great suffering to the patient. When the bots are hi the 

 nostrils only, they may be removed sometimes by using a feather 

 dipped in turpentine or very weak carbolic acid (one part of acid 

 to thirty parts of water), or creosote or zenoleum. An injection 

 of salt water or diluted carbolic acid into the nostrils with a syringe 

 is claimed to be of use. Fine, air-slaked lime is sometimes used, 

 the animals being forced to breathe it, that sneezing may be 

 induced. Dr. Lugger states in one of his reports that he met with 

 success by blowing pyrethrum up the nostrils. Anything which 

 will induce sneezing is good: tobacco snuff shaken into the nos- 

 trils, the burning of horns, leather, or feathers, in a closed shed 

 where the sheep are confined, etc. It is claimed also that equal 

 parts of turpentine and sweet oil poured into the nostrils carefully, 

 the head being held up, is excellent, care being taken that the sheep 

 may not be choked. But, as intimated above, all these remedies 

 would avail little or nothing if the bots were safely housed in the 

 bones of the forehead. 



Keeping Away the Flies. Some sheep-raisers in infested local- 

 ities maintain, from May to October, in pasture or yard, logs, 

 along which, at intervals of five or six inches, two-inch holes are 

 bored. These holes are kept about half filled with salt, and the 

 edges or the mouths of the holes are frequently smeared with fresh 

 tar. The sheep, in endeavoring to reach the salt, involuntarily 

 smear their noses with the tar, and this tends to keep off the flies.
