Trenches for Burying Animals. — Where animals are 

 to be disposed of by slaughter and burial, the digging of 

 the trench should be started as soon as possible after the 

 diagnosis has been confirmed. The owner of the affected 

 herd should, if possible, be induced to take the contract 

 for digging the trench, but if the owner refuses, or is unable 

 bo to do, a contractor should be hired to do the work. A 

 lay inspector should be detailed where possible to super- 

 vise the digging and should be instructed to remain upon 

 the premises until the work is finished. The contract 

 price for the trench should be based on an agreed price of 

 so much per cubic yard, with the further agreement that 

 the trench be completed as quickly as possible. In dig- 

 ging small trenches, the work can be frequently done 

 more quickly and cheaply if done by laborers with picks 

 and shovels, but in digging large trenches contractors 

 should be properly equipped with teams, plows, scrapers, 

 etc. Contracts should be made in writing, stating the 

 amount of dirt to be moved, whether the price is to include 

 covering the animals when killed, and all details, and 

 signed by both the contractor and the agent for the de- 

 partment. Trenches should be about 7 feet deep, 7 feet 

 wide, and long enough to allow all carcasses to rest upon 

 one side at the bottom. The length may be readily cal- 

 culated by allowing 2 feet per adult cattle. Usually 

 there is room in a trench of this size for the additional 

 number of hogs and sheep found on the average farm, 

 allowing two hogs or sheep for each cow. If the number 

 of hogs and sheep exceeds this proportion, additional space 

 should be provided in specifying the length of the trench. 

 Frequently it will be found advisable to construct a tern-
