 — (A contribution to the general topic "A national forest policy.") The writer believes 

 that it is neither practical nor expedient to compel the practice of forestry upon private 

 lands through the interstate commerce provisions of the Constitution. Several suggestions 

 bearing on the subject of a national forest policy are made. — Chan. H. Otis.

 on observation and experiments in Chorin.) Zeitschr. Forst- u. Jagdw. 51: 6-32. 1919. — 

 The war has stimulated the naval stores industry in Germany where formerly the greater 

 portion of products were imported. Consequently it became necessary to exploit the pine 

 forests of that country for stores, and experiments were started to determine the best methods 

 of turpentining consistent with least injury to the trees but at the same time securing a maxi- 

 mum flow. These experiments are fully discussed and some results are stated, especially 

 in regard to the effects of different methods of scarring on the flow of pitch. — Hermann Krauch. 



1447. Kirkland, Btjrt P. Organization of finance in forest industry. Jour. Forestry 

 17: 236-244. 1919. — Much of the lumber industry is financed by borrowed capital at high in- 

 terest rates. A reduction, in the interest rate would save annually more than enough to secure 

 a forest stand on all commercial cuttings and protect forests from fire, the present high in- 

 terest rate being due to the speculative reputation of the industry, the high cost of loans and 

 small borrowers. A Federal Forest Loan Board similar to the farm-loan institution would 

 enable the industry to become better organized. The organization, functions, rates and loan 

 restrictions of such a board are discussed in detail. — E. N. Munns. 



1448. Kitts, J. A. Forest destruction prevented by control of surface fires. Amer. For- 

 estry 25: 1264, 1306. 1919. — Forest fires are of three types — surface fires which spread over 

 the surface of the forest floor, fed by the litter; ground fires which smolder in the ground, 

 consuming the humus and sometimes the roots of trees; and crown fires which destroy the en- 

 tire forest cover. A method of prevention of crown fires, practiced during 28 years by the 

 writer in California, is suggested as a solution of the fire problem in the coniferous forests. 

 The method consists in the burning of the forest litter by surface fire control, during and at 

 the end of the wet season, burning over by rotation one-fiftieth to one-fifth of the forest area 

 each year, the periodical rotation depending upon the local rate of litter accumulation. 

 Eleven rules for surface fire control are detailed. — Chas. H. Otis. 



1449. Lane-Poole, C. E. The kiln drying of jarrah. Western Australia Woods and For- 

 ests Dept. Bull. 1. 28 p., 12 fig., 1 chart. 1919. — This paper gives a short description of the 

 process employed in kiln-drying jarrah (Eucalyptus marginata) on scientific principles. In 

 choosing a kiln with which to experiment the author was led to select the kiln invented by 

 Tiemann because of the latter's success in drying California blue gum (Eucalyptus globulus), 

 a very difficult lumber to season. The construction and operation of the Tiemann kiln is 

 described. A psychrometric chart designed to give the relative humidity for any temperature 

 at a given dew point, is appended. In the experimental runs the kiln gave very encouraging 

 results. The author suggests that it may be possible to shorten the period of drying by in- 

 serting a fan or blower between the baffles and the radiators with a view to increasing the air 

 circulation. — C. F. Korstian.
