No. 1, July, 1920) FORESTRY 07 



out trained foresters the Conservator of Forests states that it is impossible to initiate the re- 

 quired Bilvicultural work. A noteworthy feature of the report is the announcement of the 

 decision to establish a Forest Products Laboratory in Western Australia which will depend 

 on the Federal < iovernmenl for its funds. The depression of the Lumber industry which ob- 

 tained during the war still existed due to the shortage of ships. The report is appended by 

 del ailed statements of revenue and expendii ares, I imber statistics, a list of herbarium speci- 

 mens collected and identified, a list of trees raised and planted at the Ilamcl state nursery 

 and particulars of prosecutions during the year. — C. F. Korslian.

 — After nearly twenty-five years of argument and discussion, the City Commission of Albu- 

 querque, New Mexico, has ordered the cutting down of all female cottonwood trees within the 

 city limits, a ten-year cutting plan having been adopted. — Chas. II. Otis.

 1919.— Broadcast sowing succeeds well after a fire, where the ground has been prepared, and 

 in drained swamps. Even on unburned ground success is usually assured if the ground is 

 prepared by cultivation. Without soil preparation the amount of seed required is so great as 

 to more than offset the cost of cultivation. — G. A. Pearson.

 amples of forking in planted conifers.] Skogen 6: 211. 1919. — A survey of several pine plan- 

 tations showed the percentage of forked plants to be as follows: Single leader, 77 per cent; 

 two leaders, 15 per cent; three leaders, 4 per cent; more than three leaders, 4 per cent. The 

 plantations were established from 1909 to 1913. — G. A. Pearson.

 acetic, formic, and oxalic acids and methyl alcohol. Jour. Indust. Eng. Chem. 11: 691-695. 

 1919. — The data show that 17 to 20 per cent of acetic acid can be obtained from hardwood saw- 

 dust by fusion with sodium hydroxide and that a simultaneous production of oxalic acid 

 amounting to approximately 50 per cent of the dry wood is obtained. At lower tempera- 

 tures, both formic and acetic acid are produced, amounting to approximately 15 per cent 

 each. If the reaction is carried out in a closed vessel, the production of 2.4 per cent of methyl 

 alcohol results. — Henry Schrnitz.

 value of beech in mixture with various conifers. Methods of regeneration and results are 

 given in considerable detail. Series concludes with emphasis on fact that beech has played 

 a far greater role in the improvement of forest stands of Saxony than is generally perceived. —

451. Mayer, Karl. Die Rotfaule. [The red-rot.] Forstwiss. Centralbl. 41: 121-127. 

 185-195. 1919. — Discusses red rot (Trametes radiciperda) on spruce near Schongau. This is 

 a morainal region, with the tertiary sublayer exposed along canyons, and with considerable 

 areas of high moor between the moraines. The morainal deposits weather into a fresh sandy 

 loam, which with the heavy precipitation (1250 mm.) is very favorable to forest growth. 

 Where the loam is shallow or cut off by clay at a depth of 10 cm. moors are likely to form. 

 The best timber is on the "hard" soils, while that on the "soft" (moor) soils is not as good. 

 Spruce comprises 95 per cent of the stand, associated with beech and fir on the "hard" soils 

 and with alder and birch on the "soft" soils. Mayer disagrees with Sauer's theory that red
