Red Gum, The. By A. K. Chittenden (U.S.A. Dep. Agr. Bur. 

 Forestry, Bull. 58). — It will be of interest to state that the red gum 

 (Liquidambar styraciflua) which, in a strictly economic sense, is a valu- 

 able occupant of the moist lands of the lower Ohio and Mississippi 

 basins, has for long been cultivated in this country as an ornamental tree, 

 particularly on account of the beautiful tints displayed by the foliage in 

 autumn and early winter. 



In the manufacture of furniture the wood of the red gum has been 

 found of particular value, and has been much in demand during the past 

 five years. Under the name of ' satin walnut ' the wood is known in this 

 country, where it enters into the making of furniture and is largely used 

 for wainscoting. 



Six beautifully executed plates of the red gum under different 

 conditions of ground go far in elucidating the text. — A. D. W.
