BULLETIN OF THE BUREAU OF FISHERIES. 



A peculiar kind of station which is included in this general class is that 

 devoted to the collection of fishes of various kinds obtained from the overflows 

 in the upper Mississippi Valley. In the lowlands along the streams in this 

 region the spring floods receding leave disconnected sloughs and pools, which 

 either become dry during the summer or, if they remain until the winter, freeze 

 solid, and the immense numbers of bass, crappy, and other desirable species 

 therein are lost in the ordinary course of events. By seining these waters the 

 Bureau obtains large numbers of fish that would otherwise perish, returning 

 some of them to their native streams and distributing others to adjacent waters. 

 In the autumn of 1908 six cars were employed in moving the fishes thus rescued. 



The following table, giving the interior fish-cultural stations and their auxil- 

 iaries, shows that in 1908 there were operated 23 of these stations and substa- 

 tions where hatching operations were conducted and 21 others where eggs or 

 fish were simply collected: 



Hatcheries in Interior St.^tes. 



a Stations for the collection of eggs. 



6 Stations for the rescue of young and adult fishes from overflowed lands of Mississippi River and tributaries.
