PAHT II 



noble specimen at Dunmore, which is con- 2049 



ndered to be the most picturesque tree in 



the Lowlands of Scotland, and of which fig. 



8051. is a portrait after Strutt, to a scale 



o\' 24 ft. to 1 in. The height of this tree was, 



in 1S36, 67 ft. ; and the diameter of the trunk, j 



it 1 ft. from the ground, 3 ft. 9 in. ; and it j 



was estimated to contain nearly 300 ft. of ! 



timber. Among the finest specimens in the ; 



Highlands of Scotland are those in Strath- [si/y. 



spey, of a group of which Jig. 2052., to a 



scale of 24 ft. to 1 in., is a portrait by W. A. 



Nesfield, Esq. The tallest of these trees is 



To ft. high. 



The quality of the timber of the Scotch 

 pine, according to some, is altogether depen- 

 dent on soil, climate, and slowness of growth ; 

 but, according to others, it depends jointly 

 on these circumstances, and on the kind of 

 variety cultivated; and this is our opinion. 

 It is acknowledged, that the timber of the 

 Scotch pine, grown on rocky surfaces, or 

 where the soil is dry, sandy, or hazelly, is, 

 in general, more resinous, and redder in co- 

 lour, than that of such as is grown on soils 

 of a clayey nature, boggy, or on chalk : but 

 this is not always the case; for an instance 

 is given, in Lawson's Manual, of " a planta- 

 tion, recently cut down, which stood on the 

 north side of the Perth and Dundee road, 

 nearly 10 miles from the former, the seed of 

 which was, 70 or 80 years since, received 

 from the Forest of Mar; and the timber, al- 

 though grown on a poor, damp, tenacious 

 clay, besides attaining to a great size, was 

 found equal in quality to that for which the 

 above natural forest is esteemed." (Ag. Man. 

 p. 320., note.) Scotch " pine timber," Sir 

 T. D. Lauder observes, " is best in the 

 colder situations. In the warmer regions, 

 it contains a great deal of white, or sap, 

 wood. At what time the sap wood is transformed into durable, or red, 

 wood, has not yet been determined by vegetable physiologists ; and, though 

 most writers believe that the ligneous matter is deposited in the second 

 year, we are disposed to doubt the fact. More than a dozen layers of sap 

 wood may be counted on some trees; and, what is a very interesting ob- 

 servation, where trees have been much exposed to the mid-day sun, the whole 

 southern half of the tree is sometimes found to be little better than sap wood, 

 whilst the northern half may contain only a layer or two of it at the cir- 

 cumference." (Laud, (wi/p., i. p. 174.) 



The durability of the red timber of the Scotch pine was supposed, by the cele- 

 brated engineer, Brindlcy,to be as great as that of the oak; and Dr. Smith, in his 

 I . on the Production of Timber, in the Transactions of the Highland Society 

 of Scotland, vol. i. p. i66, t says that he has seen some Scotch pine grown in the 

 North Highlands, which, when taken down after it had been 300 years in the 

 roof of an old castle, was as fresh and full of resin as newly imported timber 

 from Ifemel ; and that part of it was actually wrought up into new furniture.
