KERRY WOODS. 27 



It is not proposed to discuss these results at this stage ; this is 

 done fully later, but it may be pointed out here that Groups I. and 

 IA occupy situations which approach the best obtainable in the 

 district, V., VI., and IX. approach the worst, while III. and VII. 

 may be described as growing under poor to moderate conditions. 

 The particulars relating to the growth of the various groups of 

 spruce are summarised in the table on p. 26. 



D. Miscellaneous Species and Mixtures of Species. 



i. Corsican Pine. 



Corsican Pine has been grown quite extensively in mixture with 

 other species at various elevations. In many cases it does well 

 and does not suffer from wind and snow to the same extent as 

 Scotch Pine at similar high elevations. At the same time its 

 growth is not always satisfactory. In wet places, especially, 

 many of the trees die off when 12 to 15 feet high, leaving an 

 irregular crop on the ground. Only one group was available for 

 measurement. This stood at an elevation of 900 feet in Fron- 

 derw Wood (north side of Kerry Hill) on a steep, well-sheltered 

 western slope. The following are details of the crop. 



GROUP XII. CORSICAN PINE. 



Area, 0*146 acre. Elevation, 900 feet. Age, 40 years. 

 Aspect, West. 



Soil loam, well drained, in excellent condition and well protected 

 with thick layer of needles. 



Dominant trees per acre (of mean diameter 10*5 in.) 445 

 Minor trees per acre (of mean diameter 7*7 in.) ... no 



Total 555 



Crop irregular. Density of stocking, about 0*9. 

 Sample tree: 11 = 53*3 feet. d=io*o inches. 



v=i4'34 cub. ft. f = 0*493. 



The sample tree was rather higher than the main crop, which 

 may be put at 48 feet high. 



Volume of Dominant Crop per acre = ^ ^ x 48 x 0*493 = 6, 300 cub. ft.

The quarter girth volume of the sample tree, without bark, was 

 9*3 cubic feet, which gives a total volume per acre quarter girth of 

 4,200 cubic feet for the dominant part of the crop. 



These figures show that under favourable circumstances this 

 species will give a very large return per acre in the given case 

 105 cubic feet mean annual increment quarter girth at an age of 

 40 years. 



The sample tree was still growing very vigorously and had made 

 leaders of 18 to 20 inches for the last ten years. The height- 

 growth curve is shown on page 30, and from this it will be seen
