MUSSEli FAUNA OF MAUMEE RIVER. 



29 



Station 8. Woodhurn, Ind. — Near Woodburn is a long series of 

 riffles known as Bull Eapids, where shells appear to be abundant, but 

 would be difficult to obtain, except during very low water, on ac- 

 count of the rock}^ bottom and the swiftness of the current. There 

 was a long bar here covered with dead shells, but although we waded 

 about everywhere over the coarse sand and rocks of the bottom, cover- 

 ing a large area, we found only a few live mussels. The party 

 stopped for the night with a Mr. Armbruster, just below this station, 

 and he reported finding in his cornfield on the south bank of the 

 river a large pile of mussel shells some distance from the water, and 

 made up of the same kinds as those found in the river. The presence 

 of bones and stone implements among the shells left no doubt that 

 this was an Indian kitchen midden, and that the aborigines had used 

 these mussels for food. 



Station 9. Maumee Center Bridge. — Just above Maumee Center 

 Bridge some men were busy hauling gravel out of the river bed. 

 There was a fair number of shells in the gravel, though by no means 

 enough to indicate a shell bed, and the men were of the opinion that 

 there were not many in the river. The water was turbid at the place, 

 the bottom of gravel, and the depth to 4 feet. The species noted 

 were found in the sand along the shore. 



Station 10. One mile below Antwerp^ Ohio. — The next place at 

 which the river was examined was about a mile from Antwerp, Ohio. 

 Just below the town the river has a width of 250 or 275 feet, with 

 low banks, and there is a long series of riffles. The bottom is covered 

 with coarse gravel and loose rocks. There were many dead shells on 

 bars alongshore, while the live mussels were rather scattered and 

 deeply buried among the rocks and pebbles. 



Station 11. Five miles below Antwerp., Ohio. — ^This station was 

 along the bed of the river opposite the farm of a man named Curtis. 

 A long sand bar wdth a^umber of dead shells w^as seen. On the bar 

 were noted a few Quadrula rubiginosa^ several Q. cylindrica^ a few 

 Q. uThdulata., a large number of Pleurohema clava., a few Unio gib- 

 hosus, a few Obovaria ci7vulus, several Lampsilis iris^ a few L. rectus, 

 and a large number of L. Ugamentinus, which was the most common 

 shell. Just above the bar the water was deep and sluggish and be- 

 low it v/as shallower and swifter. In the deeper water the shells 

 were widely scattered and deeply buried and consequently difficult 

 to find. In the shallow water on the slope of the bar they were also 

 well scattered, but had been actively crawling about and were easily 

 found at the end of the tracks they had made. 



Station 12. Ten miles above Defiance, Ohio. — The water was quite 

 I deep here and the river banks steep; the place was used as a swim- 

 ming hole. The bottom was rather solid, composed of fine mud and 

 sand and covered with a growth of algse, among which was a large
