 we must make exceptional sacrifices ; when 

 they return from feeding on the grass, we 

 should give them some additional fodder, or roots 

 of a generous quality. We must imitate the 

 regimen used in the country of the steppes, 

 by adding to their forage a solution of marine

 fed cattle, a ration consisting of bruised oats, 

 pounded juniper berries, gentian, sulphate of 

 iron, and carbonate of soda. 



Tor, if we neglect to take those measures 

 which are required to prevent among herbi- 

 vorous animals the development of those ordi-

 on our own soil, they will certainly afford a
