'A JOURNAIv OF THE 



passing- of a generation. For this same reason there is 

 an increasing- tendency to cut all marketable trees, 

 even of the smallest sij^e, that returns may be had at 

 once. 



(2) Even when some desire is evinced to so care for 

 woodland that the return therefrom may be reg-ular and 

 the condition of the woodland may not deteriorate, either 

 in respect to avera^j-e si^ce or choice of trees, there is 

 great ignorance shown of all requirements for tree 

 growth and of the action demanded to secure desired 

 results. , 



The larger and more thickly settled European gov- 

 ernments, recognizing these facts, have man}^ 3^ears 

 ago undertaken to place all their own forest lands un- 

 der systematic management and at the same time sup- 

 pl3% by means of their schools of forestry, the knowl- 

 edge of these methods to private land-holders or to 

 trained officers who may serve them. In many of these 

 schools series of experiments, analogous to those made 

 upon g-rains, etc., in the Agricultural Kxperiment Sta- 

 tions of the United States, have been carried on upon for- 

 est trees, todetermine the conditions of light, soil, moist- 

 ure and density of tree growth which they require 

 for their best dev^elopment, and the age they should be 

 allowed to reach before cutting, the diseases, fungous 

 and other, to which they are subject, their destructive 

 insects, and the trees, naturalU^ and those most advan- 

 tageously, associated together in forests. 



What has been done by these governments for their 

 forests will have to be repeated in modified forms bv 

 the federal and various state governments for their re- 

 spective forests as soon as the great bodies of standing 

 timber which have required the uninterrupted efforts 

 of centuries to accumulate, are destroyed or thinned
