INTRODUCTION. 
In considering the value of any branch of governmental work it is 
clearly just to take cognizance of the progress made, as evidenced 
by an increased volume of work, but improved methods and lower 
costs of producing and distributing the output are, in the case of 
fish culture, of more importance, as indicating efficiency and sus- 
tained interest in the work. 
For a number of years there has been no increase in the funds pro- 
vided for the propagation and distribution of food fishes, and only 
the very inadequate increase in compensation of faithful employees 
as provided by the so-called bonus of $240 per annum. In the face 
of this condition and the fact that the cost of all commodities, labor, 
and railroad rates increased many fold during the period of the 
World War, it is particularly gratifying to note that the bureau 
maintained its fish-cultural establishment, if not intact, still at a 
point of efficiency where it handled an increased volume of work 
without material increase in the cost of production or distribution. 
The value of modern fish culture is so generally accepted by those 
having knowledge of the facts as to need no defense and is shown 
by the action of many States in providing funds for such work, by 
the numbers of fish-cultural plants financed by commercial interests, 
and by individuals who are interested only in maintaining the fish 
supply in a given locality. 
The bureaw’s fish-cultural division is probably more completely 
organized and equipped than any similar institution in the world. 
It has been built up through a long period of years and represents 
the thoughtful and painstaking effort of many persons. It has 
reached a point in its history where its movement must either ad- 
vance or retrograde. To longer maintain the present magnitude of 
the work with the funds provided is manifestly impracticable. On 
the other hand, the opportunities for its continued enlargement and 
extension are restricted only by the facilities available.
