' In order to attain the object of management, the following 

 marking rules are proposed : 



' 1. Ten to fifteen oak trees per acre will be selected as seed- 

 bearers, the spacing being 22 to 15 yards. 



" 2. As fa* as possible sound thrifty trees of medium size and 

 of good height growth will be so retained and trees which are low- 

 branching, unsound, or large and overmature, will be avoided : 

 no minimum girth limit can be prescribed, but ordinarily the seed- 

 bearera should be over 2 feet in girth. 



" 3. Within the limits of rule 1, the precise number of trees to 

 be selected will depend on their quality as seed-bearers ; on the 

 aspect and quality of the locality and on the amount of regenera- 

 tion (including potential coppice) already existing. Obviously 

 seed trees will not be retained over complete regeneration or over 

 .poles retained under the following rule 4 (5). 



" 4. All other oak will be felled with the followingjexceptions : 

 (a) On ridges and other places where the soil is hard and 

 shallow, and nothing can be expected to replace what is 

 removed : here fellings must be very light until regenera- 

 tion becomes established. 



(6) Groups of young trees under 2 feet girth when of good 

 quality and density should be retained at the discretion 

 of the marking officer when he considers he is likely to 

 improve the quality and uniformity of the crop by 

 retaining them. Such groups should not be less than 2 

 square chains and will be marked for thinning if requiring 

 it. When in doubt they should be marked for removal, 

 reliance being placed on a new coppice crop. 

 " 5. Kokat trees will all be felled with the following excep- 

 tions : 



(a) Where their removal will seriously expose the soil, espe- 

 cially on south aspects and poor localities : here a few 

 may be retained both for their own value and for seed 

 production.
