a matter of mucli importance; cold and mountainous spots are certainly the most desirable, and yet 

 they should be such as are protected against violent tempests; for instance, crevices and recesses of 

 mountains, for when too much exposed it is very liable to be injured by the cold winds. The soil in 

 which the seed is to be sown in the spring, should be turned up, and, if possible, the clods broken 

 shortly before the preceding winter. The end of March, or the beginning of April, seems to be the 

 proper period for sowing, and the seed should not be covered over. If sown in the Autumn, it will 



r 



be necessary to turn up the ground immediately before. With respect to cutting, this should take 

 place when the trees have acquired their full height and strength, and the spots which are cleared may 

 be sown with seed of home produce. Besides furnishing timber for all sorts of masts and yards, and 

 for a considerable part of the hull of a ship, as far as planking is required, this pine is of the greatest 

 use to the common carpenter, who can turn ahnost every part of it to account. The North American 

 has discovered its value, though hitherto but little skilled in forest botany, and studiously preserves the 

 young trees from the depredations of cattle. The wood lasts as long above ground as that of any 

 known species of P'miis, but in building under ground, for door thresholds, and for the hulls of ships, 

 it should be used only in cases of necessity, as its duration in such situations is rather short, and there 

 are other woods better adapted to such purposes. It yields a very fine resin from which good turpen- 

 tine maybe prepared. The earliest propagation of P. Strohus in this country was at Lord Weymouth's 



F 



(from whom it had its name) in Wiltshire, and at Sir Wyndham Knatchbull's in Kent. Most of the 

 «eeds, afterwards sown, were procured from these places, so that our island may be said to have been 

 stocked from them. Although none of the Pines (except the Larch tribe) are deciduous, yet the 

 position of the leaves becomes Ayery different in Winter, from what they are in Summer; In the latter 

 they are much more divaricated, in the former they become nearly parallel to the stem. (Folia 

 adprcssa, et folia divaricaia.) In no species of Pine is it more exemphfied than in this.
