EXPERIMENTAL FARMS AND STATIONS. 443 



(1878), principally with the view of determining the agri- 

 cultural value of the various forms of the most important 

 manures, so as to ascertain under which form manures may 

 be most advantageously and economically applied to the 

 soil. Each station has been divided into forty plots, so 

 arranged as not to interfere with the ordinary methods of 

 farming, and the cropping is to be a four years' rotation of 

 turnips, barley, grass, and oats. The experiments are 

 under the direction of Dr Aitken, the Society's Chemist, 

 and are fully described in the tenth and eleventh volumes 

 of the present series of the Society's Transactions.
