ous species handled, caused primarily by local conditions of wind 

 and weather. The total of the egg collections for the fiscal year 

 1922 exceeds that of the previous year by more than 431,000,000. 

 It is evident that the annual egg collections represent practically 

 the maximum production of the present fields of endeavor and that 

 an increased volume of work, or an extension of the practical bene- 

 fits of artificial propagation, can be accomplished only by the de- 

 velopment of new fields. There are many points in various parts 

 of the country affording excellent opportunities for such extension 

 and promising most satisfactory results in practical returns to the 

 fisheries. Any further extension of the work can be undertaken, 

 however, only when additional funds are available.

RESCUED FISHES. 



The salvaging of stranded fishes from the overflowed lands along 

 the Mississippi River has continued to be one of the most important 

 and popular features of the bureau's work in fish conservation. Dur- 

 ing the fiscal year 1922 this work attained its greatest volume in the 

 numbers of fish handled. A total of 179,475,069 fish were salvaged 

 and either returned to original waters or delivered to applicants for 

 planting in adjacent territory. The salvaged fishes comprise prac- 

 tically every useful species indigenous to the region. The table in- 

 dicates by localities and by species the total numbers of fish salvaged, 

 the numbers restored to original waters, and the numbers delivered 

 to applicants. A full discussion of the more important details of 

 the work occurs on page 57.
