190 GENERAL THERAPEUTICS FOR VETERINARIANS 



ing is to be collected together and either burned, buried, plowed under, or 

 rendered harmless by composting or by mixing with a suitable disinfectant. 



The compost piles containing the manure, straw, feed residue and similar 

 material should be placed so that susceptible animals and imauthorized 

 persons cannot walk over them, dirty fluids flow from them to other premises, 

 strange persons have access to them, or washings from them contaminate 

 springs, water courses or other sources of water supply. The materials should 

 be thoroughly mixed in the proportion of two parts of manure to three of 

 straw, moderately moistened, and loosely piled in large heaps for three weeks. 

 After being piled in a heap, the manure is moistened with water or urine 

 (about 10 to 15 quarts to 1 square yard of manure). The remainder of the 

 process is as follows: A layer of non-infected manure, straw or turf about 

 10 inches deep, 5 to 6 feet broad and as long as desired is first placed upon 

 the ground and upon this the manure to be disinfected is piled in a heap 4 

 feet high with sloping sides. The surface of the heap is covered with a layer 

 of non-infected manure, straw, leaves, turf or other loose material four inches 

 deep, and over this is placed a layer of earth of the same thickness. After 

 remaining three weeks in this condition the manure may be removed without 

 danger. 



Manure and bedding material which has not been composted and which 

 is required to be rendered harmless (see §§ 15 to 27) must be removed 

 from infected premises in tight wagons without the employment of sus- 

 ceptible animals from other premises. In case of necessity, the manure, 

 bedding material, etc., must be wet down in layers with concentrated milk 

 of lime, unless the character of the infection requires the use of another 

 disinfectant. 



When the method of storing the manure which is permitted is such that 

 there is danger of the infectious material being spread by contaminated water 

 flowing into other premises, by the manure being accessible to strange persons 

 or animals, or by springs, streams or other water suppUes being contaminated, 

 then the manure is to be treated with concentrated milk of lime in the stalls 

 before it is removed to the place of storage. 



2. Liquid manure and dirty water, in so far as they are not used in the 

 composting of manure (No. 1), are to be disinfected with lime, concentrated 

 milk of lime, calcium chloride or concentrated solution of calcium chloride. 

 At least 1 part by volume of lime or calcium chloride or 3 parts by volume of 

 concentrated milk of lime or concentrated calcium chloride solution are to 

 be used to each 100 parts of liquid manure or dirty water. The mixture must 

 be thoroughly stirred and allowed to stand for at least 2 hours. 



3. Feed and straw stored in the rooms to be disinfected are to be removed 

 without harm in so far as the regulations do not provide that they be disposed 

 of in another manner (§§ 15 to 27).
