42 EXPERIMENT STATION RECORD. [Vol.43 



Norway spruce are growing lliriftily. lied pine and Douglas fir are making 

 less satisfactory growth, and white ash died on account of excessive moisture. 



I'^xperiinents were started in 1912 to determine the best methods of thinning 

 innnature white pine stands. The work thus far conducted shows that white 

 pine is .seriously checked by overtopping hardwoods with the possible exception 

 of gray birch. The removal of these overtopping hardwoods leads to an im- 

 mediate increase in growth provided the pines have not been suppressed too 

 long. 



Preliminary report on chemical weed control in coniferous nurseries, 

 P. C. KiTcuiN (Jour. Forestry, 18 (1920), No. 2, pp. 157-159).— A brief sum- 

 mary of results thus far secured in several National Forest nur.series, including 

 tabular data on work done by E. C. Rogers at the Savenac nursery, Haugan, 

 Mont. 



Although the work at Savenac was done primarily with the view of con- 

 trolling damping-ofC fungi through the use of chemicals, records were also kept 

 of weed growth on the various plats during 1917. The results secured indicate 

 that zinc and copper salts may be efficient in destroying weeds shortly after 

 germination, at least in the type of soil used. Experiments have been con- 

 tinued at Savenac with different strength solutions of copper sulphate, zinc 

 sulphate, and zinc chlorid. 



The management of hardwood forests in the southern Appalachians, 

 I. F. Eldredge (Jour. Forestry, 18 (1920), No. 3, pp. 284-291). — A discussion 

 of the preparation of management plans applicable to the hardwood forests in 

 the southern Appalachians, with special reference to the National Forests of 

 that area. 



Handbook of forest jirotection. — California forest fire laws, 1919 

 (Sacramento: Cat. State Bd. Forestry, 1919, p. 57). — The present handbook 

 was prepared primarily for the State fire wardens and also to inform the 

 general public of the statutes designed to prevent and extinguish forest fires 

 outside the limits of incorporated towns and cities. 



Organization for the national control of forest devastation, F. E. Olm- 

 sted (-Jour. Forestry, 18 (1920), No. 3, pp. 242-247). — The author here presents 

 an outline indicating some of the fundamental principles which might govern 

 in framing the essential administrative machinery for the national control of 

 forest devastation. 



The economics of private forestry, B. P. Kikkland (-Jour. Forestry, 18 

 (1920), No. 3, pp. 214-217).— A contribution from the University of Washing- 

 ton, in which the author discusses certain misconceptions that have arisen with 

 the commonly advanced point of view that private forestry is uneconomic. 

 Special attention is given to the rights of private property, interest returns 

 and capitalization, and taxation. 



Shall we capitalize our forests? B. A. Chandler (Jour. Forestry, 18 (1920), 

 No. 3, pp. 218-228). — A contribution from Cornell University, in which the 

 author takes the stand tliat our forests should be capitalized and discusses 

 different methods of financing forest operations. 



Annual progress report ui)on State forest administration in South 

 Australia for the year 1918-19, W. Gill (Ann. Rpt. State Forest Admin. 

 So. Avst.. 1918-19, pp. 12, pis. 10). — The usual progress 4-eport on the adminis- 

 tration of the State forests in South Australia, including data on the area of 

 forest reserves and plantations, tree planting operations, revenues, and ex- 

 penditures. Several forest plantation plans are appended. 



Afforestation in Zululand, .T. S. Henkel (Rliodesia Ayr. Jour., 17 (1920), 

 No. 1, pp. 50-52). — Notes on the present condition of forest species that have 

 been tested for a number of years at the Govex-nment experiment station at
