Mixed Herbage of Grass-Land.

grasses ; it contained much less Leguminous herbage, nearly the 
same proportion of Miscellaneous plants, and was somewhat 
more matured at the time of cutting, its order of ripeness being 
No. 6. 
Mixed mineral manures alone gave a very equally maturing 
and generally ripe crop, but with only a small proportion 
of the more grossly growing grasses ; the finer ones, however, 
mostly flowering or seeding. Leguminous plants were very 
numerous and luxuriant, but few of the Miscellaneous ones were 
so. Order of ripeness No. 2. 
Ammonia-salts alone gave a very green and unripe crop, the 
order of ripeness being No. 10. There was a dense bottom 
lierbage, with the foliage coming chiefly from the root, and very 
little flowering tendency. Upon the whole the grasses, which 
were for the most part of the smaller kinds, seemed but partially 
developed, apparently exhausted, and not likely to mature. Lo- 
lium perenne showed the most tendency to form stem and seed, 
but was fre(juently monstrous or dying. 
Nitrate of soda alone gave a crop which at the time of cutting 
was very late, dark green, and still growing, without the look of 
exhaustion exhibited by the herbage grown by ammonia-salts 
alone ; it was much more leafy than stemmy, forming a dense 
mass of grassy produce, for the most part referable to the smaller- 
leafed species ; and, as the amount of undetermined stem and 
leaf will show, the separation and identification of its com- 
ponents were unusually difficult. The order of ripeness was 
No. 9. 
Farmyard-manure alone yielded a produce which was, upon the 
whole, comparatively ripe, standing 4th in this respect, but it 
was very unequally so. All the grasses gave a fair proportion of 
stem, and they were also generally plentiful in both base and 
stem-leaves. Poa trivialis and Bromus mollis were the pre- 
dominating grasses, but there was a fair proportion of most of 
the others found on the unmanured land, the grosser species 
beinff, however, somewhat restricted in development. 
Farmijard-maniire and ammonia-salts, like farmyard-manure 
alone, gave a very unequally ripe crop, which also in order of 
ripeness was No. 4. Its characteristics were great luxuriance, 
a fair proportion of both stem and leaf, and a considerable variety 
of herbage ; but with Poa trivialis, Dactylis glomerata, and 
Bromus mollis, by far the most prominent species among the 
grasses, giving upon the whole a strong and thick-bottomed, but 
rather rough crop. 
With superphosphate of lime and ammonia-salts the crop was 
much more backward than with superphosphate of lime alone, 
coming 10th instead of 6th in order of ripeness. There was,
