The histological difference between Pinus taeda and Pinus palustris, 

 IvATiiKKiM'; (J. r.iTTiN.(; { I'roc. IikI. Acad. t<ri.. HKJS. pp. 127-129, fifjs. 6). — The 

 author points out the differences found in the woods of these si)ecies when 

 studied under the nncroscope. 



The factors given as the most ])rominen1 and also the most readily obtained 

 in distinguishing the woods of the two trees are that in Pinus twda the junction 

 of the spring and sunniier wood in the year zone is not distinct and the medul- 

 lary rays are somewhat obscure and close together, whei-eas in P. palustris the 

 sining and summer wood are distinct from each other, and the medullary rays 

 consiiicnous and farthei" apart with a ratio to those in P. ta^da of 4: 11. 



Indo-Malayan woods, F. W. Foxworthy {Philippine Jour. Sci., G. Hot.. Jf 

 ( 19(19). Ao. //. pp. ->iU9-592, pts. 9). — This work, which was undertaken primarily 

 with the view of correlating Philippine wttods with related or identical forms in 

 other regions, consists chiefly of descriptive notes of the Indo-Malayan woods 

 relative to their structure, uses, and distribution. Photographic plates of micro- 

 scopical sections showing the wood structure of some 108 of the si)ecies descril)ed 

 accompany the text. Tables showing the comparative weight and hardness of 

 eastern woods, together with lists of woods suitable for special purposes, and 

 rare, ornamental, or precious woods, and a chart showing the commercially 

 equivalent woods of the Philippines and other timber producing countries of the 

 Kast, are given and discussed, including notes on the timbered areas and future 

 supplies in these countries. 



Andaman Padouk (Pterocarpus dalbergioides), B. B. Osmaston (Indian 

 Forest Rec., 1 (190S). No. 3, pp. 239-2^).— An account of this timber tree rela- 

 tive to its habit, distribution, timber, conditions of growth, distribution of the age 

 classes, reproductive power, plantations, insect pests, and natural reproduction. 



Teak forests of Siam, C C. Hansen (Daily Cons, and Trade Rpts. [V. 8.], 

 1910, \o. 3679. pp. ,S', 9). — A brief account of the teak forests of Siam relative 

 to their management and extent of production. 



Japanese charcoal kiln, N. B. Eckho (Forestry Quart., 7 (1909), No. Jf, pp. 

 J,00. .'lOl, pi. 1). — An illustrated description is given, together with the method 

 of operating the kiln. 



DISEASES or PLANTS. 



Fungus diseases of plants, B, M. Dtjggar (Boston, New York, Chieago, Lon- 

 don, 1909, pp. Xll-\-50S, pi. 1, figs. 2J,0).— This is one of the Country Life Edu- 

 cation Series, edited by C. W. Burkett, former director of the Kansas Experi- 

 ment Station, and covers the subject of diseases of plants that are known to 

 1)6 due to fungi. After giving chapters on cultural methods, technique of fixing, 

 embedding, and staining, and physiological relations of fungi, the author de- 

 scribes in detail the important diseases of plants due to fungi, including the 

 slime molds and bacteria. In the discussion of each disease, as far as practi- 

 cable the pathological effects and other relations of host and parasite are 

 described, a clear account is given of the life history of the fungus, and sug- 

 gestions are offered of methods for the preveutiou or control of the disease.
