In Sedalia at the crossing of the two principal streets, 

 a vacant lot had stones piled upon it, and for a time this 

 shell was found there in great numbers. At Providence, 

 in local drift by the side of the railroad tracks, in about 

 a quart of material, I found this and a large number of 

 other small shells, in all more than a thousand shells. 

 Postpliocene fossils were abundant close by, but I could 

 not find any of these small ones imbedded in the ground 

 with the fossils, and think they were of living shells, 

 though most of them were bleached.
