FIELD NATURALISTS' CLUB. 257 



(4.) In carrying this out the greatest attention should 

 be paid to the condition of the pastures, so that 

 the animals should be supplied with plenty of 

 grasses, and the natural cover for the ticks 

 should be removed. 



(;").) The forcible extraction or maiming of ticks is to be 

 avoided, because this increases the pain of the 

 animal and does not allow the tick time to 

 remove its proboscis. The tick appears to be 

 able to do this voluntarily if so inclined and 

 allowed time. 



(G.) It is important to induce the tick to willingly let 

 go. Various smears are referred to. The 

 practice of throwing the animals cannot be too 

 strongly condemned, and this is necessary with 

 smears. 



(7.) AVith liquids, thorough cleansing nuw be effected 

 by using a good spray-pump such as is employed 

 for freeing plants from scale-insects. 100 cattle 

 may thus be treated in an hour by a knapsack 

 spray-pump. 



(8.) A number of types of washes for spraying are 

 selected for description. All poisonous ones 

 should be rejected as there arc: non-poisonous 

 preparations equally effective. 



(9.) Carbolic acid dips and other liquids which 

 evaporate quickly need frequent applications, 

 and should be discarded in favour of the oily 

 liquids or emulsions where the latter are equally 

 effective. 

 (10.) The best of all these is the Kerosine emulsion 

 regularly used for plants. There are many 

 formulae for the preparation of this: a useful 

 one is given. 

 (11.) On the principle that prevention is better than 

 cure, small doses of sulphur with salt are 

 preferable to spraying, in that the animal's skin 

 is thus renderd so offensive to ticks that they 

 will not attach themselves. 

 (12.) The sulphur taken into the mouth passes through 

 the tissues with various changes, emerging from 

 the skin in the form of Sulphuretted hydrogen, 

 a gas very objectionable to all vermin. The 

 best method of giving the sulphur is in the form 

 of a lick with salt.
