 effects of, and methods of controlling, molds and wood-destroying fungi. — H. N . Lee.

 72-89. 1920. — The final 4 chapters of a serial on forest organization in Saxony. The results 

 and conclusions of 100 years of consistent and continuous development along the same line of 

 organization are set forth. The determination of felling and management methods are dis- 

 cussed under the following headings: Choice of species, stand establishment, stand form, 

 stand development, stand improvement, and soil treatment. The theory and practice of forest 

 rent is discussed. The need for revision and control of organization plans is emphasized, 

 the importance of regulating the entire business of forest organization is set forth, and the 

 desirability of an effective coordination of forest administration, silviculture, forest inves- 

 tigation, and forest organization is stressed. — Joseph S. Illick.

 continued.] — Data collected to date show that pure stands of Norway spruce surpassed 

 mixed stands of beech and Scotch pine in volume and value production. There are other 

 determining factors which should be considered. The author believes that there are 

 numerous areas, aggregating a large acreage, between the good hard wood soil and the poor 

 pine soil well adapted to the production of mixed stands of Scotch pine and beech.— Joseph

 on the west slope of the Cascades in Oregon. Jour. Forestry 18: 833-836. 1920.— On sample 

 plots in Douglas fir it is found that there has been a loss of 41 trees per acre in 10 years, with 

 an increase in diameter for the stand of from 13.7 to 16.3 inches, the basal area increasing 

 from 200 to 224 square feet. The annual increment in cubic feet has fallen from 188 in the 

 1st 5 years to 80 in the 2nd, or from 1259 board feet in the 1st to 828 in the 2nd 5 years. 

 The average cubic-foot volume of the trees in 1910 was 45; in 1915, 54; and in 1920, 66.—

 1920.— A severe fire in 1919 destroyed some 150,000 acres of brush cover in southern Cali- 

 fornia. Erosion was very severe following this fire and destroyed much of the engineering 

 work designed to prevent floods. On eroded areas a small stand of annuals and perennials 

 came up from dormant seeds, which were present in much greater numbers on unburned 

 lands. The soil of slightly eroded areas contained seeds of almost as many species and 

 individuals as did the soil in non-burned and non-eroded areas. — E. N. Munns.

 —High temperatures in southern California caused "burning" of trees, due largely to extreme 

 droughty conditions. The amount of injury depended upon the abundance of water or the 

 character of the soil. Trees on loamy soils suffered least. Eucalyptus rostrata and E. ter- 

 reticornis of all the planted eucalypts withstood the droughty conditions hest.— E. N. 

 Munns.
