The State forests are composed of not a few Austrian pines, and they are greatly valued for the shelter and warmth they afford to other less hardy kinds of trees. The best results are to be obtained if planted when young, for when removed at a greater age, with roots large and rampant of growth, it is with great difficulty that they can be got to keep upright. Unfortunately the timber is of no special value. The =Corsican Pine= is equally as good as the latter for using where winds are of common occurrence, proving stout and strong, rooting well, and presenting a broad surface of hardy evergreen foliage to the blast. It is a good timber-producer, and, being well fitted for growing in patches close together, will yet be largely used for forest work in this country. About the =Scotch Pine= it is, perhaps, needless to speak, for every one who has travelled in Scotland, particularly in the more exposed northern parts, must have made himself acquainted with the capabilities of this valuable native tree. It can grow and flourish almost anywhere—on pure gravel, on the rocky mountain-slope, or by the rushing brookside, and in all these positions it seems to feel quite happy and contented, as the beautiful silvery glaucous foliage, the upright, rampant growth, and the cheery cinnamon or terra-cotta bark clearly indicate. With these three excellent storm-resisting trees for an outer barrier almost any kind of planting can be engaged in, for the shelter they afford is amply sufficient to start away into rapid growth even our only second-class hardy kinds of trees. The =Sycamore= is a good tree for planting where the storms blow loud and long, being able to withstand in a very commendable way the first brunt of the hillside winds. It is also a good timber-producer, the wood at all times being easily disposed of, and at a very remunerative price. The =Elder= and =Mountain Ash= are other valuable small-growing trees for planting on exposed ground, both flourishing apace even in very high and exposed woodlands. In the =Scotch= or =Mountain Elm= (_Ulmus montana_) we have a first-class tree for planting as shelter, while the =Alder=, =Willows= of various kinds, and the =Hornbeam= should all receive attention in the formation of woodlands on exposed and storm-swept sites. The =American Winged Elm= (_Ulmus alata_) has few equals for withstanding long-continued storms at high altitudes, for it sends out its cork-covered branches without fear of harm into the very teeth of the blast. I have noticed how well suited this elm is for planting on exposed, high-lying ground by the few examples that occur at considerable elevations in some of the screen-belts that have been formed on the flanks of the Snowdon range of hills, where the tree looks quite as healthy and happy as at lower elevations in a sheltered park.
