From a purely commercial point of view the above hard-wooded trees are the only kinds that can be recommended for planting in this country. The timber of the lime, hornbeam, walnut and one or two others at times sells at a fair price, but the small quantity offered shows that they have not been considered worthy of attention where the economic value of the plantations was being considered. CONIFEROUS TREES Amongst the many conifers that have been introduced to this country during the last century very few can be recommended as suitable for profitable planting. The following, so far as is known, are the only species to be recommended:— The =Larch= (_Larix europæa_).—Both for and against the larch much has been written and said, particularly of late years; but, however much has been said in commendation of it, there can be no doubt that to overstate its value as a timber tree in the economy of British forestry would be a task of some difficulty. When we combine its great, almost peculiar, aptitude to suit itself to nearly all conditions of soils, altitudes, and diversities of climate, its long-established value as a timber tree, rapidity of growth and ease of culture, it is clear that no other tree cultivated in this country can be ranked on a par with the larch. Unfortunately, however, of late years the larch has suffered much from disease, the predisposing causes of which may mainly be attributed to the variableness of our spring weather, and the rapidly degenerating state of the tree—the latter chiefly brought about by an injudicious selection of seed. By far too little attention has been paid to this important matter, the result being that weakness and tenderness have got into the constitution of the tree, and it is thus unable to withstand even a few degrees of frost. So weakened, blight, fungus, and ulceration find a footing, and thus the fell disease is generated about which so much has been said and written of late years. In my own opinion, strengthened by careful investigation and research, induced tenderness in the constitution of the larch is the primary cause of disease, cold winds and frost being the destructive agents, and ulceration the direct consequence. Injury to the roots of the larch in transplanting is attended with most injurious results. In corroboration of this, it may be stated that natural or self-sown trees are, in this country, almost exempt from disease. The variableness of our spring weather is, no doubt, one of the predisposing causes of disease, for although no degree of cold experienced in this country can injure the tree when leafless, yet few are more sensitive when in young foliage.
