eucalyptus oil, uiid formalin, which communicate pungent and persis- 

 tent odours might be given a trial to ward off the flies. It has been 

 observed that the flies dislike certain odours, and trials in the direc- 

 tion indicated are worthy of being made. One rubbing with paraffin 

 oil will last fully a fortnight, providing weather be dry. In fact, 

 clipping close the hair over those parts accessible to the tongue should 

 always be done, as then the flies would have a difficulty in effecting a 

 lodgement of the eggs. Moreover, when clipped, the parts can be 

 more readily anointed with the paraffin oil. Crude paraffin oil can be 

 got for about 4s. per gallon. Birds eat the grubs when they pass 

 with the droppings, so birds are inimical to the development of the 

 hot fly. Fowls allowed to scrape about dung heaps will devour the 

 bots. All droppings containing bots should be mixed with unslaked 

 lime, and the lime will kill the bots. 



When the eggs have been introduced into the stomach of the 

 horse they there develop to the bot stage, and efforts must be made 

 to rid the animal of the invaders. Some time ago the late Dr. Moore, 

 of Beulah, approached ine concerning the way horses in the district 

 were scourged by bots, and I recommended him to carry out a treat- 

 ment which I had long advocated, and he subsequently reported to 

 me that he was astonished at the result. Preliminary to the admini- 

 stration of the specific the animal is deprived of food for a few hours. 

 No food is administered, say, after about 4 o'clock in the day treat- 

 ment is commenced, but the animal may be allowed access to water. 

 At night a pint of raw linseed oil is given, and on the following 

 morning a drench is administered consisting of 



Bisulphide of carbon . . . 40-60 drops. 



Oil of turpentine ... ... 2 teaspoonfuls. 



Ether ... ... ... 1 teaspoonful. 



Beer or milk ... ... 1 pint. 



An hour or so after the administration of the drench a warm bran 

 mash should be allowed. 



The bots inhabiting the stomach will be poisoned witu the fumes 

 of the carbon bisulphide, and will be expelled dead. After three or 

 four days have elapsed the treatment should be repeated to see if any 

 of the parasites have remained behind. 



Pure bisulphide of carbon is a colorless liquid almost insoluble in 

 water, but is soluble in oils and ethers. It undergoes alteration in 

 the light, so it must be kept in a dark place. It is, moreover, 

 extremely volatile and inflammable, and must not be brought near a 

 flame, as an explosion would ensue. 



As a remedy for expelling bots gasoline also has a value. One 

 ounce of gasoline in a pint of raw linseed oil or milk should be given 

 to a draught horse. The dose should be repeated every day for three 

 days. Nearly all vermifuges are more or less poisonous in one way 

 or another, but, if properly used, they are not particularly dangerous. 



If any untoward symptoms occur after giving the bisulphide of 

 carbon drench, a pint of milk containing four teaspoonfuls of baking soda
