1075. Slightly calcareous shale, with fish remains, a few foraminifera, 
Inocei'amus prisms, and crystals of selenite. 
1080. Soft, moderately calcareous, dark grey, mottled clay shale, with 
small crystals and crystalline masses of pyrite. 
1085. Similar shale, with several species of foraminifera, some fish re- 
mains, and a large amount of pyrite. 
1090. Similar shale, with foraminifera and fish remains. 
1100-110.5. More calcareous shale, with large amount of pyrite. 
1110. Highly calcareous mottled shale, with fish remains, Inoceramus 
prisms, and 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 deter- 
mined the following, viz.: — Olobigerina creUicea, d'Orb., Q. bul- 
loides, d'Orb., Cristellarla rotulata, Lam., PlanorbuUna ammo- 
noides, Reuss, Anomalina rotula, d'Orb., Bulimina variabilis, 
d' Orh., Textularia globulosa, Ehr., Verneuilvna triquetra, d'Orb., 
Marginulina variabilis, Neug. 
1120. Very similar shale. 
1125. Slightly calcareous clay shale, with fish remains, Inoceramus 
prisms, a few foraminifera,and crystals of selenite. 
1130. Soft light-grey clay shale, with many fragmentsof shells of Inocera- 
mus and Ostrea, and many foraminifera, crystals of pyrite and 
selenite. 
1134-1140. Similar shale, with crystals of pyrite, and a few badly pre- 
served foraminifera and prisms of Inoceramus. 
1145-1180. Similar shale or marl, with pyrite, fish remains, Inocera- 
mus prisms and many foraminifera, OlobiQerina cixtacea being 
especially abundant. 
1185-1195. Slightly calcareous shale, a few fish remains, crystals of sel- 
enite and a few foraminifera. 
1205. Slightly calcareous shale, a few fish remains, and irregular frag- 
ments of calcite and selenite. 
1210-1245. Similar shale, with pyrite, a few fish remains, foraminifera, 
and prisms of Inoceramus. 
1250-1275. Similar shale, with fish remains, prisms of Inoceramus, 
pieces of shells of Ostrea, a few foraminifera and crystals of py- 
rite. 
No. 13. — The material brought up by the drill in this part of 
the boring is generally a very clarkgrey,soft, unctuous, and but 
slightly calcareous clay, from which were separated by washing 
some fine graphite-like flakes of clay shale. These have much the 
appearance of the Benton shales elsewhere in Manitoba, and were 
previously regarded as such by the writer; but as this band comes 
between two highly calcareous zones, it has been thought advis-
