porary pen at the side of the trench. The animals are 

 driven into the pen, shot, and their bodies rolled into the 

 trench after being dragged to the side of the trench either 

 by laborers or horses. Five or more feet of earth should 

 cover all carcasses. Trenches should be dug at convenient 

 points, near the affected animals, in order that they be 

 not driven over uninfected territory. If the sides and 

 one end of the trench are made perpendicular, with the 

 remaining end sloping, the animals may be generally 

 driven into the trench, and confined there by a gate 

 swung across the open end. In this position they can be 

 slaughtered in such a manner that little labor will be 

 entailed. 



Slaughtering the Animals. — No more men than 

 necessary should be kept from other work to do the slaugh- 

 tering. One inspector in charge and two assistants are 

 usually sufficient to constitute a slaughtering crew, and in 

 the case of small herds two men only are necessary. 

 Handling and slaughter of all condemned animals should 

 be done in the most humane manner possible. Animals 

 should be killed by shooting, and the work should be done 

 by a competent marksman. For this purpose a rifle of 

 sufficiently large caliber to kill instantly should be selected. 

 A .25-20 rifle or some similar gun is recommended. Aim 

 should be taken with a view to destroying the brain. 



Slashing Hides and Evisceration of Carcasses. — 

 After slaughter, all animals should have the hides or skins 

 slashed through in such a manner as to destroy the pelts 

 for commercial use. The carcasses should be eviscerated 

 and covered with unslaked lime. The amount of lime 

 used may vary with local conditions, the ability to secure 

 same, etc. A barrel of lime for every 6 to 8 cattle or 12 to 

 15 sheep or swine is usually sufficient. If the animals are 

 large, additional lime may be used. 



Filling the Trench and Disinfecting Implements, 

 etc. — The trench should be filled with earth without
