4 Dicotyles (Platygonm) C07npr€ssus, Le Conte. 



was " worked over," assorted, and deposited in such strata as we now 

 find it. Wlien it emerged, the old line of drainage was resumed, but 

 as the volume of water had vastly diminished, two small streams were 

 formed, the Olentangy occupying the eastern bank of the former 

 stream and the Scioto occupying the western. Then came another 

 submergence, and during this period there was deposited a stratum of 

 clay, varying in places from two to five feet in thickness. This last 

 stratum of clay is found superimposed on the sti^ata of sand in the 

 valley, as well as on the higher table lands, thus presenting indisputa- 

 ble evidence that the clay was deposited after the valley had assumed 

 its present form, so far as its precise topography is concerned. Fig. 1 

 presents a section taken from the State quarry, along the line of the 

 " Shortline" railroad, and above the junction of the Olentangy with 

 the Scioto. The line " E" is the surface of the ground on the line of 

 the Shortline road ; the dotted line "D" is some rods north of the 

 railway and is at the junction of Olentangy and Montgomery streets, 

 where the remains were found. D to E is a gentle declivity. 



Fig. 2 represents a section taken diagonally across the corner of the 

 lot from Montgomery street to Olentangy street. After having pene- 

 trated about twenty (20) feet from the opening of the bank, and at a 

 depth of eight (8) feet from the surface, the remains of six of the 

 smallest animals were found embedded in the calcareous clay and 

 sand, as indicated at "A"; after proceeding some six feet farther and 

 four feet deeper, the remains of the six larger animals were found at 

 " B," The digging proceeded from southeast to northwest; the 

 "snouts," or rather the tusks, were the first portions of the skeleton 

 which presented themselves. The group of remains marked "B" 

 were almost directly under a side track of the railway on Olentangy 

 street, and further excavation in that direction could not be made 

 without endangering the safety of the track. In order to obtain this 

 last group of remains it was necessary to deviate from the northwest to 

 a due north course, thus presenting a square east and west face of the 

 deposits or formation. This face presented the matter in a new light ; 

 it was observed that the strata immediately above the remains were 

 confused, presenting evidence of disturbance, so far as the deposits of 

 sand and gravel were concerned, whilst the overlying clay was, so far 

 as the eye could discern, entirely intact or undisturbed. 



The animals were lying side by side, with their heads toward the 

 southeast ; their death was sudden and violent, the jaws were crushed, 

 skulls fractured, the left side of one lower jaw was driven into the 

 palate, and various other evidences of sudden and violent death were 

 manifest. On the contrary, there was no evidence whatever that the
