DEEP WELLS IN MANITOBA. 97 



1600. Dark grey and rather hard fissile clay shale, brought up in fragments, some of 

 which are more than au inch and a half in greatest diameter. It is quite free 

 from calcareous matter, and under the microscope shows no traces of organic 

 remains, but a few globixles of pyrite may be seen. 



1605-1620. Soft dark-grey unctuous nou-caleareous clay shale, breaking into thin, scaly 

 iiakes. No trace of organic remains. 



1620-1645. Similar shale, with minute fragments offish remains. 



1655. Similar shale with traces of pyrite, mixed with a few particles of fine white soft 

 sandstone, possibly adventitious. The specimen as returned was composed 

 almost entirely of a soft, impalpable clay, and the fragments of shale, etc., were 

 procured by washing a considerable quantity. 



1660. Soft dark-grey fissile non-calcareous shale, with a few minute fragments of fish 

 remains, and pieces of concretionary nodules of limestone, and crystalline masses 

 of pyrite. 



1665-1*715. No specimens received, but stated to be a similar dark-grey shale. 



1720. A large proportion of the specimen received is a soft clay that is readily washed 

 away by the water. What remains is a grey non-calcareous clay shale, much 

 lighter in colour than the last, is rather compact, and does not break into thin 

 flakes. It contains a few fragments of fish remains, and some fine irregular 

 angular grains of clear quartz sand. 



1730. Similar shale, through which the fine sand is seen to ruu in thin streaks. 



1735. Shale similar to the last with some crystalline aggregates of pyrite, and a considerable 

 number of fragments of a hard, very slightly calcareous fine grained sandstone. 



1745. A similar dark grey clay shale, with a few fragments of soft granular sandstone, but 

 without any of the hard sandy fragments seen in the last specimen. 



1800. A light grey rather hard fissile non-calcareous clay shale with a few small crystals 

 or crystalline masses of pyrite. Some of the fragments procured were an inch or 

 more in diameter, and in one of them was a small imperfect shell of a Lingula. 

 The well has not yet reached the bottom of the Benton shales. 



Boring at Morden. 



This boring was drilled by Edward Moore for the town of Morden in the winter and 

 sirring of 1889-1890. The town is situated on the Pembina Mountain branch of the Cana- 

 dian Pacific railway, and the boring is in the middle of the town on the north side of the 

 railway track, and about 150 yards northwest from the railway statiou, the surface at the 

 well being on a level with the track. It is about a mile from the foot of the Pembina 

 mountain and near the western edge of the level alluvial plain stretching westward from 

 the Red river. The object of the bore was to obtain a large supply of fresh artesian 

 water for the use of the town. 



The machinery used was an ordinary percussion drill, and the well was cased first 

 with eight inch tubing, and then with six inch tubing, to below the bottom of the cre- 

 taceous rocks. 



The writer paid a short visit to Morden in Jirly, 1890, at the time when the work on 

 the boring"was\liscontiui;ed, and'obtained specimens of the drillings taken at very irre- 

 gular intervals. As no systematic and consecutive collection of drillings was kept,
