STATE HYGIENE 533 



These classes must be kept apart, and the animals con- 

 stituting it pass from one to the other as occasion arises. 



It is best to begin treatment with the doubtful cases. 

 clipping them all over from ears to heels, no matter how 

 cold the weather. The clipping machine must be dis- 

 infected between each case by being left in paraffin oil for 

 a short time, otherwise the risk of infecting cases by clipping, 

 which turn out to be free from disease is very great. 



Immediately after clipping they are dressed with any of 

 the recognised remedies. While the clipping and dressing 

 are being carried out the bedding is destroyed by fire, and 

 the whole stable disinfected with 5 per cent. Izal or carbolic 

 acid sprayed over the walls, mangers, stall partitions, posts, 

 flooring. The parts are then washed with freshly prepared 

 carbolized lime including the floor, and the freshly clipped 

 and dressed animals can with practical safety be put back 

 in their stables. 



The feeding and daily exercise of the animals under 

 treatment must be carefully observed. Every mange case 

 must be exercised daily in order to get the skin to act, but 

 as no blankets are to be allowed the horses must be brought 

 back cool to the stable. 



It is no part of our province to deal with the question of 

 treatment, but it is permissible to notice that over-treatment 

 and excessively irritating dressings must be avoided. The 

 use of linseed oil to the skin as a basis of treatment, 

 especially in hot climates, is only making a rod for one's 

 own back, for the linseed oil blisters the animals, especially 

 if in the sun (probably due to mustard oil as an adulterant), 

 and further, by its oxidation, forms a varnish on the hair 

 and the skin most difficult to remove. 



Bedding should not be allowed for at least a month, and 

 not in any case to horses actively affected. Blankets should 

 not be permitted until the last case is cured. 



It is obvious that all articles used in grooming should be 

 disinfected, for which purpose a large vessel containing 

 disinfectant should be kept in each stable into which 

 brushes, rubbers, curry-combs, etc., are placed immediately
