This theory is also based on a fundamentally important princi- 
ple, namely, that the administration of any large body of land must be 
centered in one authority, on an area basis, and not divided between 
severel different authorities on a functional basis. In the former 
case, the specialists eppear as advisers and assistants, while in the 
latter they have the power to carry out anv measure affecting their 
interest regardless of its effect on the whole administration or on 
other end .ernaps more importent interests. 
Cen foresters be trusted to administer game matters efficiently 
on forest areas under their charge? This would probably be answered 
in the negative by most of the game interests at present, in the belief, 
first, that foresters know too little about game, and second, that tney 
secrifice game values in an unintelligent manner, in order to secure 
higher production of commercial trees. 
at these game interests do not ssem to realize is that tne 
entire profession of forestry is based on the principle of coordinated 
use of all land resources, including agriculture, and not upon the ex- 
clusive pursuit of a hobby such as parks, or game, or a single interest 
like grazing or lumbering: that because of this fect foresters, after 
admitting grazing to the netioneal forests were the first Federal agency 
to control it in the putlic interest; that foresters were the-first 
to detect and endeavor to control erosion resuiting from destruction 
of vegetative cover on other than agricultural lands, and that follow 
ing a natural path of development foresters were the first to establisn 
modern scientific principles of game management, both abroad and in 
tne United States. 
It is netural and inevitable that as soon as a2 profession of 
trained game and fish specialists arose, their contributions to this 
science should swiftly outrenk the empirical knowledge of foresters, 
whose special training had been in other fields. with the result that 
many definite end practical suggestions were made, by which geme con- 
ditions could be greatly improved by modifying forestry practice. 
The significant point is thet foresters, instead of resisting these 
ideas, heave made immeciate efforts to incorporate them in plans for 
forest mansgament,. 
The important fertures of sound game mansgement ere, increase

this tension the entrance of men and his activities es e predator is 
the most important element, and the entire prob-em of predator control 
must be worked out on the basis, not of complete protection from all 
killing, but on the relative amount of kill which is to be secured for 
sportsmen as against animal predators. 
The most extreme and dangerous form of abnormal management occurs 
when all forms of predatory activity, including hunting, are prohibited 
successfully in the interest of the neture-loving public, who wish to 
see the wild animals in mach the same manner but in far more elevating 
surroundings and conditions than are maintained in zoos. Where this
