their appearance in some quantity at this time, but a large pro- 
portion of undesirable plants also appeared, and taking Area 2 
as an example, it would seem that the seeds,Cynosurus crsistatus 
and Poa trivialis at least should also have been included in the 
seeds-mixture, so that they might not start at a disadvantage in 
competition with other plants. It is probable also that the 
inclusion of a greater quantity Festuca elatior and (or) its variety 
£. elatior var. pratensis would give good results. On the other 
hand, Féstuca duriuscula might have been excluded, and also 
possibly Poa pratensis, Trifolium repens and Anthyllis Vulneraria. 
In this case, it would seem to be quite unnecessary to add 
Achillea Millefolium, but it might apparently have been included 
with advantage in the seeds-mixtures for Areas 6 and 7, while 
Carum Petroselinum and Arrhenatherum elatius might have been 
omitted.
