Cut on July 15. 
August 22 
Nearly all dead. 
The plants in all the boxes, except perhaps those in box 6, were 
in bad health throughout the early part of the experiment. At 
the end of May, however, some improvement took place, espe- 
cially in the case of box 6, the plants in which became vigorous 
in their development. 
The production of flowers was first observed in boxes 4, 5, 
and 6, all about the same time. With the exception of those 
in box 6 the plants were so unhealthy that little reliance can 
be placed on the comparison of the growth of this season with 
those of the former year. It is worth noticing, however, that 
whereas in 1869 the plants grown in box 2 (mineral manures) 
were uniformly of a relatively high degree of vigour, in 1870 
the reverse occurred, as was also the case in Trifolium 
pratense. 
The herbage was cut on July 15, and on August 22 it was noted 
that nearly all the plants were dead ; hence no notes on root-develop- 
ment were taken.
