Notes on the structure of the wood of the Southern pines, 



F. EoTH ( r. 8. Dept. Agr„ Division of Forestry Bui. lo^iri). 131-150, pis. 

 7, Jigs. 6). — The autlior lias made an elaborate study of the structure 

 of the woods of the 5 principal timber pines of the South, viz : Long- 

 leaf pine, Cuban pine, short-leaf pine, loblolly pine, and spruce pine. 

 The investigations failed in establishing any macroscopic or microscopic 

 features that could be used for specific determinations. The results of 

 his investigations on the characteristics of the wood structure are 

 given in detail. 



Tree culture, C. B. Waldron {Xorth Dalota Sta. Bui. 2.5, pp. 

 77-8ti,2)ls. o). — Directions are given for forest planting and the subse- 

 quent care of the trees. Compiled descriptions are given of the fol- 

 lowing trees, which are more or less adapted to the region indicated: 

 White, soft, or silver maple {Acer dasijcarpum), silver or white birch 

 {Betula papijracea), cut leaf weeping birch {B. alba laciniata pendula),

 Eussian willow {8. rifellina rtj<rw), basswood {Tilia americana), Ame,v\- 

 can or white elm [UlmKs americana), and cork or rock elm ( U. racemosa). 



Trials have been made at the station with red and white cedar, white 

 and Norway spruce, balsam fir, and Scotch june, and other evergreens, 

 which do not warrant recommending tliem for general i^lanting. 



A table of hardiness of quite a number of forest trees and orna- 

 mental shrubs is reprinted.* 



Notes on the grow^th of trees (Agl. Gas. X. S. Wales, 7 (1806), Xo. 10, pp.

 are given on Larix occidentalis, a tree A'^aluable on account of the superlative charac-
