On the Effect of a Grain Ration for Cows at Pasture. 



" That art on which a thousand millions of men are dependent for their sus- 

 tenance, and two hundred millions of men expend their daily toil, must be the 

 most important of all ; the parent and precursor of all other arts. Id every 

 country, then, and at every period, the investigation of the principles on 

 which the rational practice of this art is founded, ought to have commanded the 

 principal attention of the greatest minds."— James F. W. Johnston.
