1902. — Gamble (Manual of Indian Timbers, 1902 edition) has some notes on six 

 timbers of Indian-grown Eucalypts, as follows : — 



1. E. globulus. (With a photo-micrograph of a transverse section, magnified 



three and a half times.) 



Pores small to moderate-sized, round, in groups or in radial or oblique lines; 

 closely packed in concentric belts in the annual rings. Medullary rays fine, very- 

 numerous, the intervals between the rays smaller than in the diameter of the pores. 

 Pores marked on a longitudinal section, and medullary rays visible as a silver-grain 

 or a radial section. 



2. E. marginata Sm. 



Pores small, scanty, scattered unevenly, but chiefly in pale concentric bands. 

 Medullary rays very fine, very numerous. 



3. E. obliqua L'Her. 



Pores moderate-sized, scantly enclosed in pale tissue and arranged in short radial 

 or oblique strings. Medullary rays very fine, very numerous. Occasionally numerous 

 white wavy lines across the rays (p. 354). 



■ 4. E. amygdalina Labill. (probably E. radiata Sieb. is meant). 



Pores small, moderately numerous, in long radial lines or oblique lines first one 

 way, then the other. Medullary rays extremely fine, very numerous (p. 354). 



5. E. calophylla R.Br. 



Pores moderate-sized, usually in radial lines of 3 to 6, joined by concentric white 

 bars. Medullary rays fine, numerous (p. 354). 



6. E. tereticomis Sm. 



Pores few, moderate-sized, the rest small, in patches of pale tissue arranged in 

 concentric bands. Medullary rays very fine, very numerous, indistinct (p. 354). 



1904. — " The Timbers of Commerce and their Identification," by Herbert Stone 

 (photo-micrographs by Arthur Deane) (London, 1904) is a useful attempt to tackle 

 a very difficult subject. 



He classified the information he gives under Vernacular and Botanical Names, 

 Natural Order (now called Family), Alternative Names (i.e., of Vernaculars), Source 

 of Supply, Physical Characters, &c, Grain, Bark, Uses. &c. ; Colour, Anatomical 

 Characters — Pores, Rays, Rings, Pith, Radial Section, Tangential Section, Type- 

 Specimen (which in the book means the specimen, deemed to be authentic, he has 

 described). 



As regards Eucalyptus timbers, it is a pity that he did not get into touch with 

 at least one botanist who has specialised in timbers of the genus. If non-Australian 

 writers and, indeed, many Australian ones could only realise the limitations of many 

 of the older botanical names, their work would be very much more valuable than it is. 

 I am led to make these remarks because I look upon Mr. Stone's book as the most useful 

 of its kind that had appeared up to the date of its publication.
