The =Weymouth Pine= (_P. Strobus_), whether viewed in an ornamental or economic aspect, must be considered as another of the most valuable pines that have been introduced into this country. Admit, we must, that in certain situations the cultivation of this handsome tree has been attended with no very promising results; but then it should be remembered that, like most other trees, the Weymouth pine has its likes and dislikes of soil, as well, indeed, as of aspect and altitude. That it has succeeded well, and produced an unusually large quantity of clean and firm wood in various parts of the country cannot be denied; but then in such places its peculiar wants have been attended to. At Gwydyr Castle, in North Wales, the tree succeeds admirably, specimens fully 90 ft. in height, straight as arrows, branchless for three-fourths their length, and fully 8 ft. in girth at breast-high, being not uncommon. The soil is rocky debris, largely intermixed with vegetable refuse, fairly moist at all times, but without stagnant moisture. On the western borders of Ross-shire, at Strathkyle, where the altitudes vary from 100 ft. to 1,200 ft., the Weymouth pine is making rapid progress. We do not wish it to be inferred that the Weymouth pine alone is suitable for planting at high altitudes and on exposed situations; but that it will grow rapidly and produce useful timber in partially-sheltered districts has been proved by those who have paid particular attention to the value of the more recently introduced conifers as profitable timber-producers in this country. A comparison of the wood produced by the Weymouth pine in this country with that sent to the late Colonial and Indian Exhibition showed but slight differences, and nothing more than could naturally be expected between a mature and an only partially-developed tree. The =Scotch Pine= (_P. sylvestris_) must on no account be omitted from our list; as, especially for planting in exposed situations where few other trees could succeed, it is one of the best. Probably the principal reason why this tree has not been more generally cultivated, is on account of the low-priced timber it produces, for, of late years, it has been difficult, except in certain favoured districts, to get rid of it at a remunerative price. With the war, matters are quite different. The finest quality of Scotch pine timber, such as that produced in some of the northern Scottish counties, no doubt, is even now fairly remunerative; but, generally speaking, that grown throughout Southern Scotland, England as a whole, and also Ireland, is of so inferior a quality as hardly to fetch a remunerative price. No doubt, however, this pine will continue to be largely planted wherever shelter and ornament are of first importance: and rightly so, for few others are so well able to withstand cold, cutting blasts at high altitudes.
