SUMMARY AND CONCLUSIONS. 58 
particular plants on Area 2 in greater abundance than on other 
areas, and the smaller proportion of Agrostis spp. in the early 
history of Areas 1 and 3, and also possibly the greater prevalence 
of some miscellaneous plants such as Ranunculus repens, Bellis 
perennis, etc., on Area 3, have been considered as showing the 
effect of different forms of cultivation. 
THE EFFECT OF AFTER-TREATMENT. 
Ithas been suggested that this might have been to some 
extent the cause of the difference between Areas 6 and 7, but on 
consideration, the suggestion has not been found tenable. A 
difference in manuring has left some distinct results, but on these 
areas it did not affect any species very materially except Z7zfolium 
repens, and even in the case of this plant the effect was only 
temporary. 
THE EFFECT OF SEEDS-MIXTURES., 
On Areas 1-4 few marked differences traceable to this cause 
were met with. A difference in the quantity of the seed of some 
species, such as Dactylis glomerata, seems to have had some 
lasting effect, but in the case of other plants, such as Lolium 
perenne, the effect was generally at most temporary. The 
inclusion of the seeds of some plants which are for some reason 
exotic to the areas on which they were sown had some marked 
results. Thus, although it did not change the character of the 
herbage to any appreciable extent, Festuca e/atior persisted for at 
least 9$ years on Area 2. The most marked results were 
obtained, however, by the inclusion of the seeds of Cywosurus 
cristatus and Anthoxanthum odoratum in the seeds-mixture for 
Area 6. 
On the other hand, the seeds of some exotic plants, such as 
Festuca duriuscula and Arrhenatherum elatius, were practically 
useless, 
It is quite obvious from these results that the seeds-mixtures 
used on Areas 1-4 and on Area 7 at least were not successful 
after five or six years, It is true that some desirable plants madg
