12 HOW TO GET THE LAST TICK. 



avoided in nearly all cases by the use of a little com- 

 mon sense. Before any cattle are dipped the solu- 

 tion in the vat must be thoroughly stirred, tested, and 

 brought to proper strength. All cattle should be 

 watered not more than 4 or 5 hours prior to dipping. 

 Cattle should not be dipped when they are hot, and 

 after dipping they should be allowed to return to 

 their home range at their leisure. After dipping 

 they should be held in the dripping pen until the ex- 

 cess dip stops dripping from their bodies. The in- 

 spector should insist that cattle be handled carefully 

 and humanely at dipping vats. The best time to dip 

 is in the cool of the early morning, with the exception 

 that in some cases it is advisable to dip work oxen 

 Saturday afternoon so that they may rest the follow- 

 ing Sunday. 



The virtue of arsenic as a tick-destroying- agent 

 lies in its poisonous properties. The fact that it is a 

 violent poison to man and animals should never be 

 forgotten. White arsenic, concentrated solutions, 

 and proprietary dips must be kept in tight containers 

 inaccessible to animals and children, preferably in a 

 locked room used only for their storage. If, by, acci- 

 dent, concentrated solution or proprietary dip gets 

 on the skin or clothing it should be removed imme- 

 diately by thorough washing. Puddles that may 

 accumulate about the vat during dipping should be 

 filled with fresh earth as soon as possible and all gates 

 to the vat corrals should be kept closed between dip- 

 pings. When a vat is to be emptied the waste solu- 

 tion should be run into a pit, guarded by a fence, 

 where it will seep away, care being taken to see that 

 the seepage can not reach a water supply. 



When dipping is begun in the spring the arsenical 

 solution used should always be freshly prepared.
