13. Eugenia procera, Poir.--A tree 20 to 30 feet high, native of Jamaica, Antigua, Martinique, and Santa Cruz. A badly seasoned sample of this wood was submitted to Mr. R.H. Keene, who reported that "it is suited for bold, solid newspaper work."
Natural Order Cornaceæ.
14. Cornus florida, L. (North American dogwood).--A deciduous tree, about 30 feet high, common in the woods in various parts of North America. The wood is hard, heavy, and very fine grained. It is used in America for making the handles of light tools, as mallets, plane stocks, harrow teeth, cogwheels, etc. It has also been used in America for engraving.
In a letter from Prof. Sargent, Director of the Arnold Arboretum, Brookline, Massachusetts, quoted in the Kew Report for 1882, p. 35, he says: "I have been now, for a long time, examining our native woods in the hope of finding something to take the place of boxwood for engraving, but so far I am sorry to say with no very brilliant success. The best work here is entirely done from boxwood, and some Cornus florida is used for less expensive engraving. This wood answers fairly well for coarse work, but it is a difficult wood to manage, splitting, or rather 'checking,' very badly in drying." This, however, he states in a later letter, "can be overcome by sawing the logs through the center as soon as cut. It can be obtained in large quantities." Mr. R.H. Keene, the engraver before referred to, reports that the wood is very rough, and suitable for bold work.
Natural Order Ericaceæ.
15. Rhododendron maximum, L. (mountain laurel of North America).--Of this wood it is stated in Porcher's "Resources of the Southern Fields and Forests," p. 419, that upon the authority of a well-known engraver at Nashville, Tennessee, the wood is equaled only by the best boxwood. This species of Rhododendron "abounds on every mountain from Mason and Dixon's line to North Georgia that has a rocky branch." Specimens of this wood submitted to Mr. Scott were so badly selected and seasoned that it was almost impossible to give it a trial. In consideration of its hardness and apparent good qualities, further experiments should be made with it.
16. Rhododendron californicum.--Likewise a North American species, the wood of which is similar to the last named. Specimens were sent to Kew by Professor Sargent for report in 1882, but were so badly seasoned that no satisfactory opinion could be obtained regarding it.
17. Kalmia latifolia, L. (calico bush or ivy bush of North America).--The wood is hard and dense, and is much used in America for mechanical purposes. It has been recommended as a substitute for boxwood for engraving, and trials should, therefore, be made with it.
Natural Order Epacrideæ.
18. Monotoca elliptica, R. Br.--A tall shrub or tree 20 or 30 feet high, native of Queensland, New South Wales, Victoria, and Tasmania. The wood has been experimented upon in this country, and though to all appearances it is an excellent wood, yet Mr. Worthington Smith reported upon it as having a bad surface, and readily breaking away so that the cuts require much retouching after engraving.
