186 FORESTRY [Bot. Absts., Vol. V, 



simply a measure for the protection of old timber. An area cleaned by light burning has 

 no advance young growth to replace the virgin timber after cutting. Light burning has no 

 place in a system of forestry which seeks to perpetuate our western pine forests and make them 

 continuously productive. — Chas. H. Otis.

 274. 1920. — The details of a leasing plan are given whereby the government can lease forest 

 land instead of buying it outright, the financial burden being distributed over a long period. 

 Financial credit to forest users is at high interest rate because of the small units and a system 

 of Federal Forest Loan Boards is described. To handle forest insurance properly an insur- 

 ance organization is necessary and as a public necessity is at stake and a resource in danger, 

 this work can best be accomplished by a national organization. To these ends, legislation 

 by the states and by the government is essential. — E. N. Munns.
