640 EXPERIMENT STATION RECORD. 



The use of frustum form factors in constructing volume tables, D. Beuoe 

 {Proc. Sac. Anier. Foresters, 8 (1913), No. 3, pp. 278-288). — As a result of some 

 tests made in Idaho the author concludes that satisfactory volume tables can 

 be made by the use of frustum form factors from a far smaller number of 

 trees than was previously considered possible. 



Some financial forest problems, W. B. Bakrows {Proc. Soc. Amer. Foresters, 

 8 {1913), ^0. 3, pp. 362-365, fig. 1). — The author here briefly discusses the deter- 

 mination of forest percentage and capital invested in forestry. 



The farm wood lot, E. G. Cheyney and J. P. Wentling {New York, 191Jf, 

 pp. XII-\-3Jf3, figs. 62). — This work is presented as a handbook of forestry for 

 the farmer and the student in agriculture. 



The phases discussed include the significance of the forest, its place in 

 farm management, the growth of the tree, dendrology, practical silviculture, 

 foi'est protection, mensuration and utilization, by-products of the northern 

 woodlot, the durability and preservation of woods, arboriculture and orna- 

 mental planting, history of the forest, and forest influences. The concluding 

 chapter contains a number of tables and rules dealing with wood, lumber, 

 and tree growth. 



The management of second-growth hardwoods in Vermont, A. F. Hawes 

 and B. A. Chandlee (Vermont Sta. Bui. 176 (1914), pp. 31-86, pis. 12).— A 

 practical treatise on the management of second-growth hardwoods based 

 largely on a study of various woodland areas in Vermont. The successive 

 parts of the bulletin discuss estimating the contents of a woodlot, improve- 

 ment of the stand, yield tables, crop maturity and the selection of the crop, 

 market conditions, and enemies of northern hardwoods. Volume tables to be 

 used in estimating timber of various species are appended. 



Studies in tolerance of New England forest trees. — I, Development of 

 white pine seedlings in nursery beds, G. P. Burns ( Vermont Hta. Bui. 178 

 (1914), pp. 127-144, pis. 4, figs. 2). — This bulletin reports a study of seed bed 

 practices in the forest nursery with special reference to the development of 

 pine seedlings. 



The experiments conducted at the station indicate that damping-off of white 

 pine seedlings can be controlled by the use of formaldehyde or sulphui'ic acid. 

 A series of trials was made to determine the proper depth for planting seed, 

 and the results indiciite that in sandy soil seed should be planted not less than 

 i in. deep. When the seed is sown early in wet weather no top shade is 

 needed to get an even stand. When sown late in dry weather, however, the 

 surface soil must be kept moist by watering or by full shade top. A study of 

 the effect of lath shade on germination showed that shade reduces the tempera- 

 ture and delays the time of germination. After the period of germination all 

 shade should be removed because it hinders the development of the seedling. 

 The seed beds should be provided with solid sides during the first season, as 

 the sides greatly decrease the loss of water by transpiration. 



A brief bibliography of consulted literature is appended. 



Experimental forest planting in the Hawaiian Islands, R. S. Hosmeb 

 (Proc. Soc. Amer. Foresters, 8 (1913), No. 2, pp. 211-221).— A. general account 

 of forest conditions in Hawaii including progress made in experimental forest 

 planting. 



The tree species of Java: Contribution No. 13, S. H. Koorders and T. 

 Valeton (Mcded. Dcpt. Landb. [Dutch East Indies], No. 18 (1914), pp. VII+ 

 286). — This is the thirteenth of a series of reports on the tree si>ecie3 of Java 

 ( E, S. R., 25. p. 142). In the present report the genera and species of Aqui- 

 foliacese, Convolvulacese, and Thymeheaceje are taken up by T. Valeton: and 

 of Violacete, MoraceJB, Hamamelidaceie. Clethracea\ and Ericacoic by J. J. Smith. 



A table of contents and an index to the series as a whole are iucluded.
