To be grown in woods of the same kind in the same regions and in the same way as those we have.
Planera Crenata, Desf.—A tree from the Caucasians; excellent timber and very hardy.
Grown like the elm and in the same regions.
Caucasian Walnut Tree, Pterocarya caucasica and P. Spachiand.—Trees 20 metres in height, magnificent timber and suitable for intermingling with other walnut trees, especially Carya species.
Sequoia.—From California, where it grows to 80 or 100 metres in height by 5 or 6 metres in diameter. The species S. gigantea is that which attains the greatest size; the S. sempervirens is more modest and less exacting about the nature of the soil and its situation. The former requires porous, deep and rather clayey soil, situated on hills or in ravines. To be tried in the 3rd and 6th regions and on the mountains in the 4th and 5th. Grown as the pine.
Lime Tree.—The different European and North American species, Tilia argentea, Desf., T. nigra, Burk, and T. silvestris from Europe, might be planted in the 5th, 6th and 7th regions in heavy, porous, clay soil.
Tsuga douglasi (Fir).—From Colorado State, North America. Attains a height of 50 metres and furnishes excellent timber. Suitable for planting woods together with spruces and firs, and grown in the same way.
American Elm Tree, Ulmus americanus, L.—This is a very hardy species at least 30 metres high. Its timber, though not so very good, is yet used in carriage-building and the like. Grown like other elm species and in the same regions.
Lest it should be thought that a disproportionate amount of space has been allotted here to this matter of forestry it must be pointed out that timber of all kinds constitutes one of the greatest of the still latent treasures of the River Plate. A treasure which could be easily realized but which has hitherto been extraordinarily neglected not only in practice but even by most writers on the countries in question.
Argentina will one day export timber and ornamental woods instead of importing them as she has done hitherto; and perhaps the present difficulties of maritime transport will help to turn the eyes of both Republics to the wealth of building and other timber and fine woods they have at hand.
