of this grass as given above. It would seem, therefore, that it is 
not likely to be troublesome on good land, and that it is easy of 
expulsion by good manuring. 
7. — Cynosurus cristatus — Crested Dog's-tail Grass. 
This grass is said to have a wide range of soils, to grow on 
dry, damp, and even irrigated lands, and to vary in character 
accordingly. The opinions given respecting its value are some- 
Avhat conflicting. Some authorities consider its root-leaves, 
which are comparatively abundant, to be a favourable food for 
sheep, and that it is useful on soils and in seasons when other 
grasses are deficient. The stems seem, however, not to be eaten 
at all ; and the more recent opinions, especially those of Pro- 
fessor Buckman, are quite against its utility. It is said, how- 
ever, to be better for pasture than for hay ; but as its character 
is to die out by improvement, its perhaps now establislied in- 
feriority need not be much regretted. The time of flowering is 
June and July. 
This crested Dog's-tail grass stood lowest of any among the 
grasses, in the scale of quantity on the unmanured land. It 
there amounted, in culm, to only 1 per cent, of the total produce. 
It was found in the manured produce in less proportion still, 
especially where ammonlacal salts were used. It would appear, 
therefore, that where such manuring is employed as greatly 
increases the produce of hay, there .will be little or none of this 
doubtfully useful element, 
8. — Dactylis glomerata — Rough CocK s-Foot. 
Tlie Rough Cock's-foot is said to be very abundant and pro- 
ductive on good soils, particularly on those of a clayey nature, 
and to be much improved by cultivation. It grows well in moist 
and shady places, has broad foliage, is tufty, and reproduces 
rapidly after cutting. All stock like it, but pai'ticularly sheep, 
"early in the season, before it has become hard and coarse. Its 
time of flowering is June and July. 
Of this grass, in the condition of flowering and seeding stem, 
none whatever was found in the samjile taken from the unmanured 
plot ; none in that from the mineral manured plot ; and none in 
that from either of the plots manured with farm-yard manure. It 
would appear, however, from the notes made by Professor Henfrey 
on the growing crop of 1857, as well as from the results of the 
partial separations made by ourselves when tlie crop of that year 
was cut, lliat the Rough Cock's-foot was far more predominant in 
the second than in the third year of the experiment. The con- 
ditions of growth of the samples in which it was found in 
the third year, are consistent with its apparent exclusion under
