AMERICAN WALNUT TREES.—All give excellent timber, strong and hardier than the European kinds. Could be planted and sown in regions 3, 4, 5, 6 and 7. The best species for woods are _Carya alba_, Nut., and _C. amara_, from Canada. _C. olivæformis_ and _C. porcina_ from the central states of North America. _C. tomentosa_, Nutt., is popularly known in North America as Hickory. Tall trees, generally very leafy, and suitable for stock in mixed woods and for special wood planting, together with European and Asiatic species, cultivated like the common walnut, _J. regia_. CEDARS.—All cedars give very fine wood known as cedar-wood, whence the confusion with real cedar belonging to the conifera family. The Red Cedar of Australia, _Cedrela australis_, Muell., grows to 60 metres in height. May be planted in the 1st and 2nd regions together with the one we have, _C. brasiliensis_. _C. sinensis_, A. Juss, seems more suitable for the 3rd and 5th regions. CHAMÆYPARIS.—This resinous tree gives excellent timber in the United States, where it grows to a height of 25 to 30 metres by 0·60 metre in diameter. The species _C. Lawsoniana_ and _C. Nutkænsis_, from North America, as well as _C. obtusa_, Endl., from Japan, appear to be suitable for dense woods in regions 4, 5 and 6. DACRYDIUM.—Indigenous to Tasmania and New Zealand. The forest species furnish good carpentry timber. From some descriptions of Chilian conifers it would seem that some of these are very like Dacrydium. The most interesting species are _D. cupressinum_, Soland, _D. Franklinii_ and _D. Kirkii_, F. v. M. These trees grow to a height of 40 to 60 metres and require very generous soil, rather damp and warm, like that of the 1st and 2nd regions in our country. To be cultivated as the _Araucaria brasiliensis_ or Misiones pine. DIOSPYROS.—The _D. lotus_, from Italy, and _D. Virginiana_ furnish valuable timber know as ebony. They do not exceed 20 to 25 metres in height. A trial might be made in the 2nd, 3rd, 4th, 5th and 7th regions. DRIMYS, _D. Winter_, Forst.—A Chilian tree 15 to 20 metres in height, gives winter bark, used in medicine. To be tried for mixed woods in the 3rd, 4th and 5th regions. BEECH, _Fagus sylvatica_, L.—A European tree 30 metres in height by half a metre in diameter; gives excellent wood for boxes and wooden partitions or anything not exposed to the weather. A first-class species for the 3rd, 5th, 6th and 9th regions as a stock tree in tall woods.
