 cake which make the latter so valuable for correcting the 

 scouring tendency of watery grass or roots. As a rule it is only

 time. It may safely be discontinued as soon as the cows have 

 become accustomed to the grass. 



On the general question of the use of concentrated feeding 

 stuffs for dairv^ cows on grass, readers are advised to refer to a 

 paper in this Journal for April, 1918, p. 11. In this paper

 in fact the latter half of July, when the grass may begin to 

 fail in quantity and quality. 



For dairy cows kept under town or suburban conditions, 

 where grass is not available, the ration should at present prices 

 include a large proportion of palm kernel cake. Other suitable
