IN EXTRA-TROPICAL COUNTRIES. 171 



Guinea, at 3,000 feet. The tree attains a height of 200 feet. 

 It yields the fragrant balsam known as Liquid Storax. 



Liquidambar Formosana, Hance. 



China. A silk-producing insect is reared on this tree (Hance). 



Liquidambar orientalis, Miller.* (L. imberle, Aiton.) 



Asia Minor. This tree also yields Liquid Storax, which is 

 vanilla-scented, containing much styrol and styracin, and 

 thus used for imparting scent to some sorts of tobacco and 

 cigars, also for keeping moths from woollen clothing. Its use 

 in medicine is more limited 'than in perfumery. 



Liquidambar styraciflua, Linne. 



The Sweet Gum Tree. In morasses and on the springs of 

 the forests of North America, with a wide geographic range. 

 Endures severe frost. The crown of the tree attains vast dimen- 

 sions; the stem 10 feet in diameter. The terebinthine juice 

 hardens, on exposure, to a resin of benzoin odour. Wood fine- 

 grained. The bark contains about 8 per cent, tannin. 



Liriodendron tulipifera, Linne. 



The Tulip Tree of North America. One of the largest trees 

 of the United States, and one of the grandest vegetable pro- 

 ductions of the temperate zone. In deep fertile soil it attains 

 a height of sometimes 140 feet, with a straight clear stem up 

 to 9 feet in diameter. The Tulip wood, also inappropriately 

 called Poplar, is highly esteemed and very extensively used 

 wherever this tree abounds, uniting lightness with strength 

 and durability. It is of a light-yellow colour, fine-grained, 

 compact, is easily worked, and takes a good polish. It is 

 employed for house-building, inside as well as outside, for 

 bridges, furniture, coach-building, implements, and a variety 

 of other purposes. From its uniformity and freedom from 

 knots and disinclination to warp or shrink, it is much used 

 in Canada for railway cars and carriage-building, chiefly for 

 the panelling (Kobb). The bark yields 8 per cent, tannin. 

 As this tree is difficult to transplant, it sjiould be grown on 

 the spot where it is to remain. Though of slow growth, it 

 would be a great acquisition for the rich lands of our mountain 

 forests. 



Lithospermum canescens, Lehmann. 



North American Alkannet. This, as the vernacular name 

 indicates, offers a dye root.
