Meramec River, oue specimen. Taken by book and line. 
I was informed that the Meramec River at the mouth of the Spring Outlet used 
to be an excellent place to catch Black Bass {M. salmoides and ill. dolornieu), “Crop- 
pies” [A. rupestris), and other species of sun-flsh, with hook and line. About 6 miles 
below the Spring Outlet a dam was built across the Meramec River. Since then there 
has been a noted scarcity of the game fishes at this point. The dam was built about 
four years ago. No fishway has been erected at the dam.

II. — The Gasconade River Basin. 
The headwaters of the Gasconade are farther west and south than those of the Mera- 
mec River. The river flows in a northeasterly direction and empties into the Missouri 
River about 30 miles below the mouth of the Osage River. We visited the Gasconade
