that used on Area 6. The after treatment was also different in 
that Area 7 was not mown for hay. 
Area 8. Adjoining Area 6. 
Altitude: 850 feet. 
Soil: Type i. (p. 3). 
ffistory ; This area has formed part of the sheep walk already 
referred to for an unknown period (probably over a hundred 
years), but there is evidence that it was under cultivation at some 
remote period. The presence of imperfectly burnt limestone 
cores shows that it has been limed, but otherwise it is not known 
to have been manured. At the time of examination, a consider- 
able proportion of the field was over-run by Ulex europaeus, but 
on the part examined only scattered bushes were found, and in 
between, the herbage was typical grass heath. 
It will be seen that these eight areas fall into two clearly defined 
groups. Areas 1-5 are mainly on soil-type ii, and have generally 
been regularly cultivated on the long rotation system. The slope 
of these is also much more gentle than that of Areas 6-8, and 
they are much more easily accessible. 
Areas 6-8 are on soil-type 1. The character of the herbage 
natural to these situations at a late stage of stabilisation when 
untended is shown by the analyses of the herbage of Area 8 
(Tables IV. and V., pp. 16a, 164). 
The results obtained for these eight areas are especially 
valuable on account of the facts that some of them have been 
repeatedly examined, and that the soil conditions for each group 
are almost perfectly comparable. The examinations in each year 
were also made for all areas in August and September. 
Further particulars are given in Table II. (p. 10). 
ft seems probable that the plant had been sown on part of the field for 
fodder purposes.
