I. Graminaceous Heebage. 
1. — Lolium perenne — Common Rye-Grass. 
This grass is reputed to be suitable to a great variety of 
soils, but to vary very much in character according- to external 
conditions. It is easily propagated, is luxuriant and succulent, 
and yields an earlier feed than most other grasses. It is relished 
by stock, yields good hay, and is, in fact, one of the most gene- 
rally useful of grasses. It flowers in June and July, 
The grass having these reputed characters stands at the head 
of the list as to quantity in culm, not <mly on the unmanured 
plot, but on several of the others also. What proportion of the 
detached leaf and undeveloped stem, on the different plots, belonged 
to this grass, we were not able to determine. In the condition of 
flowering or seeding stem, the produce without manure contained 
lG-8 per cent, of it, that by purely mineral manures 23-4 per 
cent., that by ammoniacal salts alone 14*7 per cent., that by the 
"mixed mineral manure" and 400 ll)s. of ammoniacal salts 32-2 
per cent., and that by the "mixed mineral manure" and 800 lbs. 
of ammoniacal salts only 121 per cent, of it. Against these ])ro- 
portions of flowering and seeding Lolium, on the unmanured and 
artificially manured plots, the produce by the farm-yard manure 
contained 29 per cent, of it, and that by the farm-yard manure 
and ammoniacal salts only 14 9 per cent. 
The general result in regard to the amount of Rye-grass in
