able to group it in with the Niobrara formation. The following 
list gives the particulars of some of the beds: — 
1280. Dark grey non-calcareous clay shale, with a few fish remains and 
many crystals of selenite. 
128.5-1295? Dark slightly calcareous shale, with a few prisms of 
Inoccramus and fragments of fish remains. 
1300 ? Similar shale, with a few specimens of Olobigerina cretacea. 
1305-1345. Dark, unctuous, non-calcareous clay shale. 
1350. Similar shale, with fragments of a nodule of calcareous iron- 
stone. 
1355-1380. Similar shale breaking into minute flakes. 
1385. Slightly more compact shale. 
1390-1395. Similar shale, with a few crystals of selenite. 
1400-1405. Similar shale, without selenite. 
No. 14. — This series is a downward continuation of the last, 
the shale gradually becoming more calcareous, till it appears to 
terminate in a band of coarse fragmental limestone, called sand- 
stone by the driller. From this limestone band there was a con- 
siderable flow of water which rose rapidly in the pipe to within 
eight feet of the top. The water had a flattish taste from the 
presence of salts of soda. This limestone band is regarded as the 
base of the Niobrara formation. The following is a serial de- 
scription of the beds: — 
1410. Dark grey non-calcareous clay shale, with a few rotaline foramin- 
ifera, and some moderately large fragments of the shell of Inocer- 
ainus. 
1415-1425. Similar shale, with a few fragments of fish remains, but no 
foraminifera. 
1430-1445. Similar shale, with a few prisms of Iivicerdinus. 
1450. Lighter grey calcareous clay shale, with large and small prisms 
of the shells of Inoceramus, pieces of siiells of (Mrea, and a few 
fragmentary fish remains, 
1455. Similar shale, with a large number of foraminifera, Ghihi^erina 
cretacea being especially abundant. 
1460-1485. Similar shale, with a few Inin-evumuH prisms, and a greater 
or less number of small foraminifera belonging to such genera as 
Textularkt, A7iomalina, etc. 
1490-1510. A light-grey calcareous shale witii immerous specks of 
pyrite, many small species of foraminifera, prisms of Inoceramus, 
and pieces of the pearly shell of Oatrca, and lisli remains. 
1515-1555. A harder grey calcareous shale, holding similar organic re- 
mains, in varying quantities.
