REPORT ON THE FORESTRY EXHIBITION. 1 37 



and educative exhibits. The class of specimens showing the 

 rate of growth of trees was particularly outstanding. A hybrid 

 larch from Keir estate, raised from Dunkeld seed, showed 

 remarkable growth for its age of only fifteen years. It was 

 about 43 feet long by 8 J inches q.g., b.h., and each "annual 

 ring" was of great breadth. Eight poles, exhibited by His 

 Grace the Duke of Atholl, formed a very illustrative com- 

 parison of the rate of growth of various species of conifers in 

 spite of their slight disparity in age. These were as follows: — 



Approx. q.g.b.h. 

 ins. 



Two specimens of abnormal growth of trees were exhibited. 

 These were natural grafts of elm and of beech, but were more in 

 the nature of curiosities. 



Some very fine specimens of Scots pine, spruce, larch, and 

 Douglas fir were shown in the class for scantlings and poles. 

 Two poles, one of European larch 75 feet by Z\ inches q.g., b.h., 

 and one of Norway spruce 7 J inches q.g., b.h , and fully 60 feet 

 in length, were striking exhibits in this section. The former was 

 approximately 90 years old, absolutely sound, and gave what 

 was probably the highest form-factor possible for a tree of this 

 age, and the latter served as the flag-staff in front of the stand. 



The class for plants and trees damaged by fungi and other 

 agencies was a very instructive and attractive feature of the 

 show. Quite as interesting, though not so large an exhibit, was 

 a mounted collection of tree leaves. 



An elaborate planting-board was exhibited, and while no 

 actual test of its utility was made, probably its commendable 

 point is the adjustable notches for holding the seedlings. 



Perhaps the most striking exhibit in the Forestry Exhibition 

 was the larch log from Drummond Hill, Kenmore, which was 

 18 feet by 41 inches q.g., containing about 210 cubic feet. Two 

 large boards about 4 feet wide, one of "Parent" European larch 

 and the other of Weymouth pine, were also worthy of mention.
