264 FORESTRY [BoT. Absts., Vol. VIII, 



1862. Lamb, G. N. American grown cork. Amer. Forestry 27: 15-16. 5 fig. 1921. 



1863. Lapeyrere, M. E. The Landes of Gascony. Trans. Roy. Scottish Arboric. Soc. 

 34: 155-167. 1920. — A historical review of the development of the Landes as a timber and 

 turpentine producing region.— C R. Tillotson. 



1864. Lr. Aus ein Zypressenhain in Amerika. [A cypress grove in America.] Wiener 

 Allg. Forst- u. Jagd-Zeitg. 38: 270. 2 illus. 1920. — A note on Monterey cypress (Cupressua 

 macrocarpa), with a description of the peculiar gnarled growth. — F. S. Baker. 



1865. M'Pherson, Alex. Commercial forestry in the Highlands. Trans. Roy. Scottish 

 Arboric. Soc. 34: 178-181. 1920. — Present tax laws make it impracticable to grow mature 

 timber in the Scottish Highlands although timber of a superior quality can be produced there. 

 The growing of pitwood should be the staple form of forestry. Plantations 19 and 27 years 

 old disposed of for this purpose have yielded returns above interest of 16s. 9d., and £3 4s. 5d. 

 per acre respectively. Pitwood on a 19-year rotation is a more profitable investment for 

 land owners than sheep farming.— C. R. Tillotson. 



1866. MoTTL, Karl. Die forstlichen Verhaltnisse im oberen Friaul. [Forestry situation 

 in upper Friuli.] Wiener Allg. Forst- u. Jagd-Zeitg. 38: 250-251, 255-257. 1920.— A descrip- 

 tion of the Aupatal or Val d'Aupa in upper Friuli, from a general and forest standpoint. This 

 valley is in the Dolomite Alps in a region noted for torrents. It has good natural forests, 

 mostly of spruce, but they have been much mismanaged. The article includes a description 

 of the principal timber bodies and general forest conditions. No statistical information is 

 included. — F. S. Baker. 



1867. Pack, A. N. Pulpwood from British Columbia. Amer. Forestry 26: 715-719. 

 8 fig. 1920. 



1868. Peschatjt, Roman. Elektrizitat und Forstwirtschaft. [Electricity and forestry.] 

 Allg. Forst- u. Jagd-Zeitg. [Wien] 38: 129-130. 1920. — Large power developments are planned 

 on the Danube and other Austrian streams; there is considerable irregularity of flow, however, 

 and dams will be necessary. The present over-cutting on higher watersheds and the unre- 

 stricted use of litter is tending to make the run-off still more irregular. The maintenance of 

 forest cover is necessary for the most complete utilization of water for power, as is demanded 

 by the proposed hydro-electric developments in Austria. — F. S. Baker. 



1869. Petraschek. Die weitere Entwicklung der Kiefern-Hartznutzungstechnik. [Fur- 

 ther development of the turpentining technique in the pine.] Wiener Allg. Forst- u. Jagd- 

 Zeitg. 38: 279-281, 285-287, 291-292. 1920.— This is a review and compilation of articles by 

 many writers. It covers the anatomical and physiological factors governing resin production 

 and flow, and the different methods that have been devised for tapping the trees and securing 

 the resin, particularly the experimental methods using different forms of chipping and differ- 

 ent frequencies. — F. S. Baker. 



1870. Printz, E. Schwedens Holzhandel und Holzindustrie. [The Swedish limiber 

 industry.] Wiener Allg. Forst- u. Jagd-Zeitg. 38: 219-221. 1920. — This is a statistical article 

 based on 2 books: "La Suede, son peuple et son Industrie" by G. Sundbarg, Stockholm, 

 1900, and "Eine forstliche Studienreise nach Schweden" by Gabriel Janka, Vienna, 1914.— 

 F. S. Baker. 



1871. Ragl, F. X. Streunutzung in bayrischen Staatswald. [Use of litter in Bavarian 

 state forests.] Allg. Forst- u. Jagd-Zeitg. [Wien] 38: 89. 1920. — During the war, regulation 

 of the use of litter was relaxed and the annual consumption rose from about 735,000 cubic m. 

 to millions. Many forests are now completely cleared and the demand far exceeds the supply. 

 Reproduction is falling off and production is decreasing. Growth is less a function of stocking 

 than of ground conditions, as shown by 2 similar adjacent areas. In the first the litter is
