340 REPoRT OF THE Farm SUPERINTENDENT OF THE 
Since the hay was cut, all the grass plats have been top-dressed 
with well-rotted yard manure, and the shady, moist weather, com- 
bined with the effect of the manure, has strengthened the turf and 
produced a good aftermath for winter protection to the roots. 
FERTILIZER EXPERIMENT ON GRASS. 
One-sixth acre plats were laid off across the division fence 
between two fields, F and G, so that each field included one-half 
of every plat. The fertilizers were sown April 26. During the 
spring and early summer the weather seemed very favorable to 
the growth of grass, being cool and moist through May. 
The growth on field F was clover and timothy, with by far the 
larger portion of clover, except on some of the plats. On field G | 
timothy was-the predominant grass, and there was a small amount 
of clover. 
As the growth increased, it became evident that the nitrogenous 
fertilizers were exerting a very marked influence on the grass of 
field F, though the clover was not noticeably increased on any of 
the plats. On field G the increase was similar, but less marked, 
though the outline of those plats where nitrogenous fertilizer was 
used could be traced from a considerable distance. 
The following tables give, for both fields, the kind of fertilizer, 
amount and cost of each; hay harvested from the plats and the 
per cent of increase, where there was any, due to fertilizers:
