FORESTRY. 



Neudamm forestry manual, A. Sciiwappach et al. {Neudammer Forster- 

 f.chrhach. Xeudainni, 1908, 3. ed., XIX+818, i)ls. 6, figs. 203; RepeUtorium, 

 pp. 228). — The first edition of this work, which is offered as a guide for instruc- 

 tion and practice as well as a handbook for the private forest owner, appeared 

 in 1899. The present edition has been considerably enlarged and revised. The 

 work is diveded into 9 parts, treating in detail the following phases of forestry: 

 Botany, zoology, locality factors, forest mathematics and mensuration, sylvi- 

 culture, utilization, protection, valuation, and hunting, fishing, bee culture, 

 and fish and game protection. An appendix deals with the measures and laws 

 relative to the insurance of workmen and forest otficials. In addition to the 

 text figures there are colored illustrations of 117 different forest insects. 



The work is accompanied by a supplement containing 1,431 questions and 

 answers, with cross-references to the related paragraphs in the manual. 



Forest survey methods, A. H. D. Itoss {Canad. Forestry Jour., Jf (1908), 

 Xo. 1, pp. 39-52). — A discussion of methods employed in making a complete 

 forest survey which the author states includes a more or less accurate plane 

 and topographic survey of the tract under examination, a careful estimate of 

 the amount of timber upon it, a determination of the rate at which the timber 

 is growing, and a study of the conditions of light, moisture, soil, and other 

 factors influencing both the present and future condition of the forest crop. 



Handbook on forest mensuration of the white pine in Massachusetts, 

 II. O. Cook {Boston, 1908, pp. 5-'j0, figs. 8, dgms. 5). — A handbook prepared 

 by the author under the direction of the State Forester, F. W. Rane. with a 

 view to furnishing the people of Massachusetts with a practical working 

 knowledge of commercial forest values. The data given include log scales, 

 volume tables, yield tables, financial rotations, thinnings and growth tables, 

 together with miscellaneous notes of interest chiefly to lumbermen and mill 

 owners. Descriptions and illustrations of instruments for measuring heights 

 as found in Bulletin 36 of the Forest Service of this Department (E. S. 11., 14, 

 576) are also given. 



Fertilizer experiments with pine on high moorland, C. von Tubeuf 

 (\atunr. Ztscln: Forst n. Loiidiv., (J (1008), Xo. 8, pp. 39.)-',07, figs. 3). — Potash, 

 phosphoric acid, nitrogen, and lime were tested both alone and in various com- 

 binations as a fertilizer for pine seedlings in new moorland soils. The investi- 

 gations were started in 1897 and concluded during the present year. 



Good results were secured whenever phosphoric acid was used alone or in 

 combination with one or more of the remaining elements, but the largest, most 

 luxuriant, and greenest plants with long needles and well-developed buds wei-e 

 produced by the use of a complete fertilizer. Phosphoric acid in basic slag was 

 much less available than that in bi-sodium phosphate. Superphosphate influ- 

 enced the plants unfavorably, hence it is advised that a quick-acting phosphate 

 be used on the high moorland. The lack of phosphoric acid, a dwarfed condi- 

 tion of the seedlings, and the presence of anthocyanin, indicated by a red 

 coloration of the pines, appear to coincide, although a red coloration was noted 

 to some extent with large and luxuriant-growing seedlings. 



The author is of the opinion that the formation of anthocyanin occurs under 

 too varying conditions to be given any definite biological exiilanation. It is 

 suggested that the lack of pliosi)horic acid necessary for albumin and cell build- 

 ing may prevent the utilization or conversion of sugar, which thus becomes 

 stored up and leads to the development of anthocyanin.
