EXPERIMENTAL FORESTRY AREA IN WALES. 25 



Scots pine plays a part in the composition of ten of the plots, 

 and, on the whole, has grown satisfactorily up to the present. 

 In addition, small numbers of plants of this species, grown from 

 seeds procured from various countries, have been given a place 

 on the area in order to test the influence of heredity. 



Corsican pine has been made use of in several cases on 

 account of its resistance to the effects of wind-storms at high 

 elevations. As is well known, young plants of Corsican pine are 

 very poorly provided with lateral roots (" fibre "), and are, there- 

 fore, apt to suffer when being planted out. It was found 

 advantageous to use young plants that had been transplanted 

 the previous season, and also to plant after the growing season 

 had commenced. Some planted as late as the 8th of May, when 

 they had already began to develop the leading shoot, grew better 

 than any other. 



One whole plot (i^ acre) is given over to the Pacific 

 arborvitae {Thuya giganted). Unfortunately, a long period of 

 dry weather, with east wind and frost, followed immediately 

 upon the planting and caused a considerable number of deaths. 

 The gaps, however, were filled with fresh plants, and now the 

 plot is looking quite well. It is evident that this species is 

 rather susceptible to such influences, but since establishing itself 

 it has proved perfectly hardy. 



The common silver fir has been planted on a few of the high- 

 lying sections, as its deep-rooting qualities may come in useful 

 there. 



The smaller plots contain species which are perhaps less 

 likely to become forest trees than those which have been 

 mentioned above. They include such trees as the Servian 

 spruce {Picea Omo?ica), American larch {Larix microcarpa), 

 Lawson's cypress ( Chamcecyparis Lawsoniana\ Colorado Douglas 

 fir, Abies grandis, Abies nobilis, Abies concolor, Picea puvgens, and 

 a few others. 



The shelter-belt, which has already been alluded to, is com- 

 posed of the quicker-growing, hardy, broad-leaved trees, inter- 

 spersed with evergreen conifers, particularly pines. Briefly 

 stated the arrangement is as follows : — To the outside, where the 

 trees bear the brunt of the storm, are placed the mountain pine 

 and white American spruce. Further in occur sycamore, 

 Norway maple, hornbeam, birch, white alder, ash, rowan, 

 Norway spruce, Corsican pine, Austrian pine, Scots pine and
