3. That a plan be drawn up, setting forth the future treat- 
ment of all woods, regard being had— 
(2) To making the most of the woods financially, 
without any special desire to obtain immediate, 
in preference to future, returns. 
(4) To the probable supply of labour available. 
(c) To giving the best object-lesson in the treatment of 
woods of this description from a practical point of 
view, according to the methods of scientific forestry. 
(dz) Care to be taken that the Lodge Inclosure may be 
treated so as not to interfere with the amenities of 
the tenant of the residence, Alice Holt Lodge. 
In consequence of the last condition, it has been decided to 
deal separately with the Lodge Inclosure at the end of this part 
of the Report. 
With regard to the condition 3 (c), it may at once be stated 
that the woods will give the best object-lesson by being treated 
in a rational manner, in accordance with the instructions indicated 
above. 
2. TREATMENT OF THE Oak-Woons. 
On reference to the data given in Part I., it will be seen that 
the distribution of oak-woods, according to classes, is as follows 
(Lodge Inclosure always excepted) :—

Oak-woods of the 1st class (mean height 60 feet and over), 297 
Oak-woods of the 2nd class (mean height 40 to 60 feet), 851 
Oak-woods of the 3rd class (mean height under 40 feet), 293 
Total, 1441 
As regards the treatment of the third-class oak there can be 
no doubt. The data given in Part I. show that these woods 
attained, in eighty to eighty-five years, a mean height of under 
40 feet, a mean diameter of 8 inches, and that the stock on 
the ground cannot be reckoned at more than 400 cubic feet of 
timber and five cords of firewood per acre. These are such poor 
results, that conversion into more useful species is indicated. As 
a matter of fact, this process was actually commenced some years 
ago by the Hon. G. Lascelles, and has been continued since, so 
far as labour was available. : 
The sample areas taken in first-class oak areas show an 
average height of 61 feet, a mean diameter of 15 inches, and a
