48 EXPERIMENT STATION RECORD. 



Note on the absorption of water by certain timbers, R. S. Peakson (Indian 

 Forester, 40 (WUf), No. 10, pp. 513-515, pi. 1). — Data are given on the behavior 

 of a number of Indian species of timber, with special reference to the absorp- 

 tion of moisture when completely immersed in water and the evaporation of 

 moisture from the timber after removal from the water. 



The lumber industry. — II-III, IV {JJ. S. Dept. Com., Rpt. Comr. Corpora- 

 tions on Lumher Indies., pts. 2-3 {lOUf), pp. XX+264, pis. 13; 4 {1914), pp. 

 XXI +933, pis. 3^).— Part II of the statistical survey of the lumber industiy 

 of the United States continues the subject of standing timber discussed in part 

 I (E. S. R., 30, p. 844). The Concentration of Timber Ownership in Im- 

 portant Selected Regions of the timber area is discussed in detail and illus- 

 trated by ownership maps of large regions in "Washington, Oregon, California, 

 Idaho, and Louisiana. 



Part III deals with Land Holdings of Large Timber Owners, showing a cor- 

 responding concentration of land ownership which was observed in connection 

 with the study of timber. The main fact brought out is that 1,694 timber 

 owners hold in fee 105,600,000 acres, or over one-twentieth of the land area 

 of the United States. 



Part IV deals with Conditions in Production and Wholesale Distribution, 

 including Wholesale Prices, also including combinations among manufacturers 

 and wholesalers to fix prices. 



The method and purpose of securing velocity measurements in the man- 

 agement of log slides, J. Glatz {Mitt. Forstl. Versuchsw. Osterr., No. 38 

 {1914), pp. 1-8, pi. 1, figs. 2). — The author here describes a method of equipping 

 experimental log slides with electrical apparatus for making velocity determina- 

 tions of various kinds and classes of logs, the object of such measurements being 

 to secure fundamental data for the proper construction of slides. 



Yields from the destructive distillation of certain hardwoods, L. F. 

 Hawley and R. C. Palmer {U. S. Dept. Ag)\ Bui. 129 {1914), pp. 16, figs. 3). — 

 The investigation here described was undertaken in order to furnish informa- 

 tion relative to the distillation value of certain hardwoods not usually used 

 for distillation, such as the oaks, red gum, tupelo, and hickory. Comparative 

 data on species commonly used for distillation, such as beech, birch, and maple, 

 were also secured. The results are considered to be of especial interest to 

 manufacturers of by-products. 



Resin tapping in Austria, A. Kubelka {Mitt. Forstl. Versuchsiv. Osterr^ 

 No. 38 {1914), pp. 35-55, figs. 2). — ^A descriptive account of the resin and tur- 

 pentine industry in Austria, including information relative to resin yielding 

 trees, methods of tapping, silvicultural management of black pine stands, and 

 distillation processes. 



Tables and instructions for use with latex hydrometer, B. J. Eaton {Agr. 

 Bui. Fed. Malay States, 2 {1914), No. 12, pp. 314-322).— The tables and instruc- 

 tions here given are intended for use with the hydrometer, previously described 

 by the author (E. S. R., 31, p. 444). 



DISEASES OF PLANTS. 



[Plant diseases in Ontario], J. E. Howitt {Ann. Rpt. Ontario Agr. Col. and. 

 Expt. Farm, 39 {1913), pp. 35-38, 45-49, figs. 3).— The author states that during 

 the past season the plant diseases which received the most attention at the 

 Ontario Agricultural College were potato scab, black knot, orange rust of 

 blackberries, hollyhock rust, loose smut of oats, dry rot of potatoes, club root 

 of turnips and cabbage, Fusarium blight of asters, plum pockets, leaf spot or
