together in the southern enclosures (known as Knockall’s and 
Marian’s), there is no difficulty in treating them separately from 
the larger group of original woodland.” 
Under the above circumstances, Mr Hill proposes to under- 
take the conversion of 2286 acres of the present coppice-with- 
standards into high forest, and to apply a more regular treat- 
ment—as coppice-with-standards—to the 999 acres comprised in 
the Knockall’s and Marian’s Woods. In both cases, the com- 
position of the crops will be improved by planting after each 
cutting. Excluding Bircham Wood, 44 acres, the author divides 
3241 acres into four working circles, two of which comprise 
2242 acres under conversion to high forest, and two comprise 
the 999 acres to be worked as coppice-with-standards. He has 
formed this number of working circles with the objects of distri- 
buting the work, and the annual supply of produce, over four 
different localities; of securing the advantage of moderate-sized 
felling areas, which here will not exceed from 20 to 25 acres 
each; of facilitating, in the working circles under conversion, 
the selection of areas to grow on at once into high forest; and, 
lastly, of giving greater elasticity and freedom to future manage- 
ment when the conversion has been effected. 
Two blocks, aggregating 678 acres, of the working circles 
under conversion have been set aside to grow on at once into 
high forest, and the remaining 1564 acres will for the present 
continue to be treated as coppice-with-standards, on a rotation 
of thirty-five years. It is proposed that, after the expiry of the 
first and of each succeeding period of thirty-five years, further 
areas shall be set aside to grow into high forest, until, in the 
course of time, the conversion of the whole of these two working 
circles has been gradually effected. The 678 acres now set aside 
will, in the meantime, have become fit for regeneration as high 
forest, and ultimately the rotation for these two working circles 
may be fixed at one hundred and fifty years. 
The rotation for the two working circles to be treated per- 
manently as coppice-with-standards, has, for the present, been 
reduced to twenty-five years, on account of the prevalence of 
hazel in the crop. 
A felling is to be made annually in each of the four working 
circles, with an additional intermediate thinning in the areas set 
aside to grow into high forest. 
Mr Hill thus forecasts the condition of the High Meadow
