DEEP WELLS IN MANITOBA. 95 



1085. Similar shalo, with several species of forarainifera, some fish remains, aud a large 

 amount of pyrite. 



1090. Similar shale, with foramiuifera and fish remains. 



1100-1105. More calcareous shale, with a large amount of pyrite. 



1110. Highly calcareous mottled shale, with fish remains, Inoceramus prisms aud many 

 foraminifera. 



1115. Dark and light clay shale, both highly calcareous, containing pyrite, prisms of 

 Inoceramus, fish remains, and many species of foraminifera, of which Mr. C. 

 Davies Sherborn has kindly determined the following, viz. : — Giobigerin acretacea, 

 d'Orb., G. bulloides, d'Orb., Cristellarla rolulata, Lam., PlanorbuUna ammonoides, 

 Reuss, Anomaiina rotula, d'Orb., Bulmina variabilis, d'Orb., Textularia globulosa, 

 Ehr., Verneiiilina triqiieira, d'Orb., Marginulina variabilis, Neug. 



1120. Very similar shale. 



1125. Slightly calcareous clay shale, with fish remains, Inoceramus prisms, a few foram- 

 inifera and crystals of selenite. 



1130. Soft light-grey clay shale, with many fragments of shells of Inoceramus aud Ostrea, 

 and many foramiuifera, crystals of pyrite and selenite. 



1134-1140. Similar shale, with crystals of pyrite, and a few badly preserved foraminifera 

 and prisms of Inoceramus. 



1145-1180. Similar shale or marl, with pyrite, fish remains, Inoceramus prisms and many 

 foramiuifera, Globigerina crelacea being especially abundant. 



1185-1195. Slightly calcareous shale, a few fish remains, crystals of selenite and a few 

 foraminifera. 



1205. Slightly calcareous shale, a few fish remains, and irregular fragments of cakite and 

 selenite. 



1210-1245. Similar shale, with pyrite, a few fish remains, foramiuifera, aud prisms of 

 Inoceramus. 



1250-1275. Similar shale, with fish remains, prisms of Inoceramus, pieces of shells of 

 Ostrea, a few foraminifera and crystals of pyrite. 



No. 13. — The material brought up by the drill in this part of the boring is generally 

 a very dark-grey soft unctuous, aud but slightly calcareous clay, from which were separ- 

 ated by washing some fine graphite-like flakes of clay shale. These have much the 

 appearance of the Benton shales elsewhere in Manitoba, and was previously regarded as 

 such by the writer, but as this baud comes between two highly calcareous zones, it has 

 been thought advisable 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. 



1285-1295?. Dark slightly calcareous shale, with a few prisms of Inoceramus and frag- 

 ments of fish remains. 



1300 ?. Similar shale, with a few specimens of Globigerina crelacea. 



1305-1345. Dark unctuous non-calcareous clay shale. 



1350. Similar shale, with fragments of a nodule of calcareous ironstone. 



1355-1380. Similar shale breaking into minute flakes. 



1385. Slightly more compact shale.
