DISPOSAL FOR BY-PRODUCTS. 173 



Hoofs were sold to a Paris Contractor at Fr. 32 per 100 kilos. 



Hair was taken over by the Eailway Operating Division, for 

 piston packing. 



Blood was desiccated, and at the Abattoir at Boulogne a 

 certain amount was taken over by the Eoyal Air Force for the 

 manufacture of " Stickit " for Aeroplane wings. 



By special arrangement, the Inspector Q.M.G. Services 

 (Messing and Economies) used the Turbine Fat Extractors for 

 the Extraction of Beef and Mutton fat from the swill of units, 

 wherever an Economiser was installed. His profits from Fats 

 must have been enormous ; the dried product of the swill was. 

 mixed with the desiccated flesh. 



13,670 carcases were handled by the Horse Carcase Econo- 

 misers up to 31st March 1919, and the gross takings amounted 

 to £55050. Profits would have been greater if Economisers- 

 could have been installed earlier, but it will be realized that the 

 very essential munitions of War take a much more prominent 

 place in the priority of import. However, when duly installed 

 they produced excellent results, and they were certainly very 

 hygienic, and quite free from the putrid or unpleasant smell 

 which may attend a wet process of disposal. 



It was not practicable to adopt Horse Carcase Economisers. 

 in Army Areas to deal with animals died and killed. The 

 utmost that could be done was to flay the died and destroyed 

 and send the hides to Line of Communication for curing. The 

 hides of wounded animals were of little value, hardly repaying 

 the trouble or cost of flaying. 



No serious Contagious Disease cases were included even in 

 this method of disposal.
