issolated it by the culture method. The contents of 125 gelatin 

 culture tubes were dissolved in 50 litres of water. In this he 

 soaked 80,000 cubes of bread each about 1 c.c. The bread was 

 scattered through the 75 hectares infested with 10,000 to 30,000 

 mice. The total cost was very slight. Within 3 days after the 

 scattering of the bread sick and dying mice were to be seen on 

 all sides. The microbes were found in their blood. After 15 

 days scarcely a mouse could be seen alive and in their burrows 

 great numbers of carcasses were present. The microbe is said to 

 be similar to that of duck cholera, but fowls are not susceptible 

 to it Cats, dogs, fowls and domestic animals are not injured 

 by it. It is proposed to try this method on the gophers which 

 destroy so much grain in the West.
