even-aged one, or into a conglomeration of small even-aged stands 

 varying from each other by 60 years. 



Fabricius questions some of Kubelka's conclusions as to the 

 efficacy of his method, such as ; that insect damage is greatly reduced ; 

 that danger from storms is little greater than in virgin forest. Kubelka 

 recommended the method for general application under all conditions 

 in the forests of central Europe, although he has only tried it on a few 

 private forests for six years or less, and the high yields in material and 

 money which he claims were the result of the methods he seeks to 

 change. It is doubtful whether at this time Europe is in condition to 

 suffer the loss in forest production which must result from transform- 

 ing existing forests into small broken-up stands. W. N. S.

It is now proposed to standardize forest maps 



Standard Forest in British India, and many of the symbols sug- 

 Maps for gested are of value to American foresters. It is 



British India especially interesting, therefore, to read a criti- 

 cism of the proposed standard symbols and colors 

 for forest maps written by a technical forester, because they show that 

 forest working plans in India are further advanced than forest work- 

 ing plans on our National Forests in the United States. 



Special boundary symbols in red are suggested for working circle, 

 felling series, coupe and subcompartment, 



Howard argues for a scheme to show the different silviculture sys- 

 tems in colors: Uniform system (including strip system, group sys- 

 tem, etc.), rose; selection system, yellow; clear-cutting system, green; 

 coppice with standard system, blue; coppice system, gray: improve- 

 ment-felling system, light brown; unworked areas, pale blue. 



The scheme for showing species is based on a diagramatic picture of 

 the seed of the species to be depicted, or as an alternative, the capital 

 letter of the name of the species, as for example, capital "D" for 

 deodar; whether the species was predominant or auxiliary would be 

 shown by putting th symbol or key letter above or below a line. 



Howard also argues for three quality classes, for a symbol to show 

 the average age of the stand, or if irregular in age, the letters (i. r.) 

 and a number to show the periodic block, coupe number, compartment 

 number, and sub-compartment number. It will probably be some 

 years before our National Forests, in the West at least, require such
