however, such a girth is not often attained in less than twenty-five years, 

 and such a height is rearly attained in a century. Under favorable 

 conditions an average of 30 feet in height, with trunks 6 to 8 inches in 

 diameter at the base, may be expected in trees ten years from the seed. 



" Uses of the Tree and its Products. 



The principal commercial uses of the camphor tree are for the 

 production of camphor and camphor oil. Camphor is employed ex- 

 tensively in medicine. It enters into the composition of many kinds of 

 liniments for external application. For liniment it is used especially in 

 combination with olive oil. It is taken internally for hysteria, nerv- 

 ousness, nervous headaches, diarrhoea, and diseases affecting the ali- 

 mentary canal. It is a specific in cases of typhoid fever and cholera. 

 Camphor fumes have been used with success in cases of asthma. It has 

 been used very extensively to keep insects out of furs, woolens, etc. In 

 Japan, camphor and camphor oil are used in lacquer work. The oil is 

 somewhat similar to turpentine, and could doubtless be used to advan- 

 tage in varnishes and shellacs. It is now used in the manufacture of 

 toilet soaps. In Japan and China it has been used for illuminating pur- 

 poses, but it produces a smoky flame. 



" Among the secondary uses of the camphor tree the most impor- 

 tant is tor ornamental planting. Its bright evergreen leaves, rapid 

 growth, and long life make it valuable for this purpose. In Japan and 

 China it has been the principal tree planted in the temple courts for many 

 centuries, and in those countries it takes the place of the historic oaks 

 of England. It has been extensively introduced into Southern Europe 

 and South America for ornamental purposes. 



" The wood, wiih its close grain, yellow colour, and susceptibility 

 to polish, taking a kind of satin-like finishes exceedingly valuable in cab- 

 inetwork, especially for making drawers, chests, and cupboards proof 

 against insects. The leaves and young branches, although they have 

 but a slight odour of camphor, are packed with clothing or scattered 

 about unused rooms to guard against insects. 



" The tree produces an abundance of berry-like fruits, which are 

 used in Japan and China to make a kind of tallow. The fruits are 

 greedily eaten by chickens and birds. 



" Conditions of successful Cultivation. 



" For most of the secondary purposes, the camphor tree may well 

 be cultivated wherever it can be made to live; but for commercial dis- 

 tillation, and for the production of wood for cabinet purposes, it must be 

 grown under the most favourable conditions. The minimum winter 

 temperature should not be below 20 ° F., and this minimum should be 

 of rare occurrence. The soil, preferably sandy and well drained, should 

 be irrigated unless there are abundant rains. Fifty inches of water 

 during the warm growing season is desirable, and much more may 

 well be used where the air is very dry. 



u An abundance of plant food, rich in nitrogen, is required for rapid 

 growth, but the kind of fertiliser that can be most profitably applied 

 will vary according to the character of the soil in each locality. In the
