About one mile east of this section, near the northeast corner of the George 

 Eubanks survey, in a well that was being dug on Mr. Gould's place, the most 

 of the way for thirty feet is through a shaly limestone and blue clay that has 

 a great many Avicuhpecten imbedded in it. One-half mile southeast of that 

 is a hill showing the yellow limestone at the top that was first seen in Section 

 39 and elsewhere along the bank of the bayou; below that was the sandstone 

 seen at the school house, as mentioned in the previous section. 



On the top of the hill mentioned, and resting directly upon the yellow lime- 

 stone, is a bed of conglomerate. I have not seen it elsewhere, and it is prob- 

 ably local.
