1020. Gerry, Eloise. American storax production: results of different methods of tap- 

 ping red gum trees. Jour. Forestry 19: 15-24. 1921. — Commercial storax used in pharmacy is 

 obtained from the Orient. During the war extracts were made from the red gum {Liquidambar 

 styraciflua). Experiments were carried out in Louisiana to determine the proper methods. 

 Heaviest yields were obtained from trees with parallel horizontal scarification as against the 

 vertical scarring or girdling. Tapping early in spring gave the heaviest yields. Some sub- 

 stance should be used to prevent the entrance of decay on the open wounds. — E. N . Munns.

 of pulp, and keys for identifying the same. — H. N . Lee.

 1920. — The cuttings in this park 20 years ago were the first made under the direction of a for- 

 ester. A 2nd cut has been planned under the direction of a resident forester. In the 1st 

 cutting the selection system was used, which has been shown to be inadvisable in this type 

 of country. Markets now accept woods which formerly were discarded, and small sizes are 

 as much in demand as the larger ones.— Two general types are recognized, the balsam swamp 

 or softwood land, and the hardwood tj'pe. In these the percentage of dominants in the re- 

 production does not differ materially from that in the older stand. Criticisms of the more 

 recent cuttings answered by the author are: Lack of a sustained annual yield basis; 2nd cut 

 too heavy; too rigid a diameter limit applied; cuttings show lack of immediate supervision 

 by a forester; spruce is not increasing; cull hardwoods remain on the ground; and the large 

 burn is not being made productive. It is shown that the work has thus far been a credit 

 to the forestry profession, though the forester in charge has failed to secure the establish- 

 ment of a thrifty forest of young growth unhampered by heavy-foliaged hardwoods. The 

 administration and improvements made on the property are excellent. — E. N . Munns.

 1918. [Net yield of state forests of Saxony for "l918,] Tharander Forst. Jahrb. 71:59-71. 

 1920. — A series of 11 tables giving a classified account of the receipts and expenditures 

 during 1918 of the 110 state forests of Saxony; also a summary of receipts and expendi- 

 tures by forest districts. The total receipts from the 110 state forests was 31,616,330 marks 

 and the expenditures 7,530,860 marks, leaving a net yield of 24,085,470 marks. The total 

 forest capital of the state forestfe of Saxony is placed at 448,151,700 marks. — Joseph S. Illick. 



1024. Jentsch. Die Stellung des Waldes und der Waldwirtschaft im Volksstaate mit 

 besonderer Beziehung auf Sachsen. [Where forestry stands in Germany.] Tharander Forst. 

 Jahrb. 71: 1-29. 1920. — The war made heavy demands upon the forests of Germany which 

 will continue during the reconstruction period. Methods of handling and controlling for- 

 ests will change in consequence of the war and the subsequent revolution. Important eco- 

 nomic questions and policies are discussed, among them the socialization of forests, an embargo 

 on timber, effect of rising prices of wood on forest management, and stronger control over 

 privately-owned forests. Expropriation of private forests is not regarded as feasible, but 

 stronger state control over privately-owned forest land is recommended. The latter is desir- 

 able especially in Saxony, where private forests are numerous, and only 173 out of a total of 

 67,030 private forest holdings exceed 250 acres in size. — Joseph S. Illick, 



1025. Krauch, Hermann. Alinement volume tables. Jour. Forestry 18: 831-832. 1 fig. 

 1920. — The method of preparing alinement volume charts and the use of a volume table pre- 

 pared in this manner is described. Alinement charts make possible a rapid transcription of 

 volume data with less chance for error. — E. N . Munns.
