[The synonyms of the specimen in question are : — Acer Negundo, 

 Linn. ; Negimdo Aceroides, Mosnck and Torry and Gray ; Negundo 

 fraxinifolium, liutt and Loudon; iSTegundum Americanum, Eafinesguc; 

 the ash-leaved maple, Negundo, or black ash. 



Forestry was acquired by the new proprietors under the publish- 

 ing conditions complained of by our correspondent. In any case we 

 cannot begin a new volume with next number. — Ed.] 



SiK, — I enclose a twig of elm, which is greatly valued in this 

 district for its timber. It grows to a great size, has rough bark, 

 and very strong limbs, and is known on this estate as Dutch elm. 

 Would you kindly tell me if that is the proper name, as I am 

 doubtful ? 



I may mention that the timber is of much more value than that 

 of the English elm, — Yours very faithfully, 



Geo. Gallie.

[The specimen sent is a twig of Ulmus sulierosa — Dutch cork- 

 barked elm. 



Will correspondents please send not scraps, but good specimens 

 if possible, with fruit and flowers ? — Ed.] 



iY^IF USi: OF WOOD. 



DEAR SIR, — The Exhiliition of Forest Products lately held in 

 Edinburgh, with its paper pulp, and paper cottage, and paper 

 tanks, and paper water-mill, may have made many familiar with 

 applications of wood fibre of which they had not previously thought. 

 I enclose yet another which is being patented in America by Mr. 

 Hough, whose father is perhaps the best-known student of forestry 

 in America, Dr. F. B. Hough, to whom a medal was awarded by 

 the Executive Committee of the Exhibition. It is, as you will see, 

 a visiting card, consisting simply of a transverse section of wood. 

 What I send is such a section of the Acer ruhrum. They are thin, 

 but so strong that they may be used either with a copperplate or a 

 common letterpress. Oblique sections are also made. Such sections 

 of some woods have a beautiful gloss ; but unhappily they have a 

 tendency to curl up, which the transverse sections have not. This, 

 it is hoped, may be overcome. — Yours truly, 



John C. Bkown.
