28 OURINE-The Great 



have attained perfect growth they voluntarily 

 loosen their hold and allow themselves to be car- 

 ried along the alimentary canal until they escape 

 with the feces. In all cases they sooner or later 

 fall to the ground and when transferred to the soil 

 they bury themselves beneath the surface In order 

 to undergo transformation into the pupa condition. 

 Having remained in the earth for a period of six 

 or seven weeks they finally emerge from their pu- 

 pal-cocoons as perfect dipterus (winged) insects, 

 the gad-fJy. It thus appears that bots ordinarily 

 pass about eight months of their lifetime in the di- 

 gestive organs of the horse." 



It is a very common expression to hear by- 

 standers exclaim: "Your horse has the bots," 

 when the animal is suffering from some internal 

 pain. Bots in large numbers may interfere some- 

 what with digestion, but beyond this they are as a 

 general thing harmless. They loosen their hold 

 during the spring months and pass out in large 

 numbers, but so far as medicine is concerned, none 

 is necessary. In order to prevent the horse from 

 having bots, it would be necessary to scrape off 

 all the eggs deposited by the gad-fly and destroy 

 them. 



OVERREACH. 



This trouble is caused by the shoe of the hind foot 

 striking the quarters or heel of the fore foot. It 

 mostly happens when the animal is going at speed 

 and is more common among trotters, pacers aad 

 runners. 



SYMPTOMS.— The quarter or heel is cut and 

 bruised, or the horse may grab and pull his front 

 shoe off. Horses accustomed to overreaching are 

 very "bad breakers," owing to the pain which ex- 

 cites them.

TREATMENT.— If th© parts are cut, bathe 

 thoroughly with cold water, and dress the wound 

 with CURINE diluted with three to four times 

 water, place a little cotton or oakum over the
