character to those of Rothamsted ; but the condition as affected 
by recent manuring was very much higher. In fact, the land, 
so far from being at the commencement in a practically exhausted 
condition requiring liberal manuring, was described as being 
already in a well cultivated and fertile state, and prepared for the 
wheat crop. The quantities of ammonia actually applied were, 
therefore, obviously very excessive. The result, under these cir- 
cumstances, was, as might be expected, much higher produce
