than on the latter area. Even with this small seeding, how- 
ever, the grass was much less represented on Area 6 than on 
Area 2 up to 64 years, but at 74 years it was more developed on 
Area 6. The increase on Area 6 at 74 years seems to indicate 
that this grass is encouraged by heavy grazing with sheep, but 
during the examinations abundant evidence was found that this 
was not due to their neglect of the plant itself. 
The behaviour of the grass on these areas suggests that under 
these conditions it is not a very strenuous competitor, although it 
may recolonise the land rapidly and become very prominent in a 
young pasture where a suitable seed-distributing centre is near 
at hand. In the absence of such a centre it colonises but slowly, 
and in such cases, if the presence of the grass is desired in the 
pasture, colonisation on suitable soil may be greatly accelerated 
by the inclusion of even a very small quantity of the seed ina 
seeds-mixture. 
Foleus lanatus. 
Armstrong’s results (I) show that the presence or absence of 
this grass in a pasture is no reliable indication of the quality of 
the pasture, but ‘results obtained by Hall and Russell (6)' seem 
to show that on the whole it is more plentiful on the better 
feeding pastures. 
The seeds of the grass are never intentionally included in 
seeds-mixtures, but low grade seed samples of Lolium spp. 
especially may contain considerable quantities of them (8), 
(II), (14). 
It was not recorded on Area 8 (grass-heath) nor on Area 7 
at 54 years, and only in very smail quantity on the latter area at 
64 years, but on Area 6 it was fairly well represented except at 54 
years. The cause of its abnormally low proportion in this year as 
compared with other years is not known, but it may be a 
temporary effect of the Basic Slag which was applied at 4 years, 
The manure had no such effect on the grass on Area 2 however, 
as on that area there was a continuous increase from 2-5 per cent. 
1 These results were obtained by quite a different method of analysis, so 
they are rarely referred to in this paper.
