156 TRANSACTIONS OF ROYAL SCOTTISH ARBORICULTURAL SOCIETY. 



well-grown Douglas were seen. The creosoting tank was also 

 inspected. In the Byres Wood the substitution of coniferous 

 timber crops for old-oak-coppice is being carried out, 

 the species used being Douglas, Alberlia7ia, Thuja plicata, 

 and Cupressiis Nootkatensis ; the ages vary from i to 8 years. 

 From the Byres Wood the party proceeded to the Ringwood, and 

 were shown a plantation of pure Douglas 14 years old and already 

 lightly thinned. The forestry museum and policies near the 

 Castle were next visited. The museum is entirely local, and 

 contains only specimens of timber, fungoid and insect pests 

 found on the estate. 



The night was spent at the Birnam Hotel. 



Next morning, 30th June, the party proceeded via the Perth- 

 Dunkeld Road to Bee Cottage. The plantations visited were, 

 one of pure Douglas fir 8 years old, and experimental plots of 

 Albertiana, TJiuja plicata, and the supposed hybrid between the 

 European and the Japanese larch. The Douglas fir plantation 

 was found to be in a flourishing condition and was much 

 admired, while the experimental plots aroused keen interest. 

 From an educational point of view nothing could be finer. 

 Many silvicultural problems of fundamental importance are here 

 elucidated. The immunity of the Albertiana from snow damage 

 was well illustrated. The trees, which now average 12 feet in 

 height, were last winter laid flat on the ground, and all that 

 indicated their presence was the mounds of snow which covered 

 them. An attempt was made to release as many as possible, but 

 when the snow melted, every stem regained its perpendicular 

 position, and there is now not the slightest trace of snow bending 

 visible in the whole plantation. The experimental plot of Thuja 

 and Douglas fir is doing well, but it would appear that the 

 Thuja will ultimately be suppressed by the Douglas. The 

 hybrid larches planted in 1908 now average about 20 feet in 

 height, and show every sign of continued vigour of growth. 



At Rohallion, seed and potting boxes made of Douglas fir 

 wood were seen. These boxes have been in use for 10 years, 

 and the wood is still in good preservation. In the vicinity of 

 Rohallion Lodge was shown a plantation of larch planted at wide 

 intervals, and filled up after a lapse of 5 years with Douglas fir 

 and other species. 



The party then ascended the shoulder of the hill to Allan's 

 Bridge, from which a magnificent view of a wide stretch of
