accordingly. In other words, to deal with about 15 acres each 
year, or 300 acres during the twenty years. This would leave 
844 acres to be dealt with during the following forty years, or 
21 acres a year. ‘The thinnings in the new coniferous woods 
will commence after about twenty years, so that no reduction of 
income need be apprehended at the end of twenty years. The 
thinnings will gradually increase in value, so that a rising income 
may be expected during the conversion period. At the end of 
sixty years the woods will be in a condition to give a high 
sustained annual yield. 
Every acre of second and third-class oak, to be dealt with during 
the next twenty years, may be expected to give about the 
following yield, considering that about three-fourths belong to the 
third-class and one-fourth to the second class :—timber, 350 cubic 
feet ; cordwood, 4 cords; oak bark, about 3 tons.

The value of the growing stock may be put down as equal to 
about £18,000. The inclosure is capable of yielding at once a 
considerable income, which would increase as time went on if it 
were treated on purely financial grounds. However, it contains 
a lodge which is leased for a term of forty-one years, and it has 
been laid down that this inclosure shall be so managed as not to 
interfere with the amenities of the tenant of the lodge. Under 
these circumstances, the following treatment is proposed :— 
(a) Zhe Coppice- Woods. 
With the exception of a strip running along the north-east 
boundary, these woods are situated at the southern extremity of 
the inclosure. In their middle are situated 14 acres of young 
coniferous woods, and the remaining coppice might also be 
converted into conifers as soon as it becomes ripe for the axe.
