Section 4. — Diameter Increment of Whole Woods. 
Laii's which govern the diameter development of whole woods in general : — 
I. In even-aged woods considerable difference will always exist between the 
diameter of the different individuals constituting the crop : the fewer 
the number of stems per acre and the older the crop the greater the 
difference. 
II. With the above exception, the development of the mean diameter of a 
whole crop differs from that of a single tree in exactly the same man- 
ner as the mean height of a whole wood differs from that of a single 
tree. 
Data relating to the development of the diameter of Sal in whole 
woods are not available. 
The mean diameter of the shoots of an even-aged coppice wood, 20 
years of age, situated in the Nawabganj Forest, United Provinces, a poor 
quality of locality owing to insignificant depth of soil, was found to be 
8 inches. 
The following table shows the development of the girth of a coppice 
wood in the Tikri Working Circle of the Gonda Division, United Provin- 
ces, and in the Kalsi Coppice of the Jaunsar Forest Division, United 
Provinces : —
