128 J. D. Dana—Discharge of the flooded Mill River, 
very much the coarsest; along Mill River valley, it is toa great 
extent, in contrast with the stratum it overlies, a cobble stone de- 
posit, and this evidence of hurrying waters continues along its 
course through the New Haven plain for a mile and a half to the 
Bay.* Further, the height of the deposits where the stones are 
coarsest is ten feet below the normal height, because in the 
dashing flood, the finer material was drifted off. 
4. The flow from Mill River into the Quinnipiac basin dimin- 
acter diminishes, and finally, in the course of three-fourths of a 
mile, the beds consist largely of sand. 
5. The great plain of stratified drift, southeast of East Rock, 
contributed by the Mill River torrent, ; 
6. The Quinnipiac waters added little to the height of this 
drift-deposit plain or terrace: for the upper stratum bears evr 
dence of Mill River action nearly or quite to its top. There 
v 
te the Quinnipiac waters after the Mill River floods had su 
sided. 
7. Mill River—now not over fifteen miles in length—is an 
example of a little stream that was a great river during the 
Glacial flood. It owes this partly to its having been one of the 
the New Haven plain had reached their extreme height.
