Deep Well at Deloraine. — Tyrrell. 333 
portion of the smaller. The following are the diameters and 
depths of the various casings: ^\ inches, 658 feet 7 inches; 5^ 
inches, 1226 feet 10 inches; ^\ inches, 1777 feet; 3^ inches, 1920 
feet. 
The drillings were raised with anordinar}' sand pump. In man}- 
parts of the well water had to be poured in to enable the drill to 
work, and the drillings to be removed; but when the Dakota sand- 
stone was reached the water rushed into the casing, carrying along 
a large quantity of sand which filled the tube for about 250 feet. 
This sand packed very hard and was taken out with .some consider- 
able difficult}'. Afterwards the water rose more quietly to a 
hight of about 100 feet below the sui'face, where it stands at pres- 
ent. The water is slightly saline, an analysis by Mr. Hoffmann 
of the Canadian Geological Survey showing it to contain in an 
Imperial gallon (=1.2 American or wine gallon) chloride of so- 
dium 309 grains, bicarbonate of soda 94 grs., sulphate of soda 28 
grs. , other ingredients 15 grs. 
In June, 1889, the well had reached a depth of 975 feet and up 
to that time no clearly-marked specimens had been kept, and the 
log is given below ver}^ much as it was received from the driller. 
At a depth of 1050 feet the collection of a sj'stematic series of 
specimens from every five feet was begun, and was carried down 
to 1285 feet, between which depth and 1335 feet six specimens 
were obtained, numbered merely in consecutive order. This latter 
depth was reached in October, 1889, and then operations were 
suspended for a short time through lack of the necessary funds to 
continue the work. During this month the writer paid a short 
visit to Deloraine, examined as far as possible the work done up 
to that date, and obtained from Messrs. Stuart, Martin and Cowan 
the specimens collected. In company with the same gentlemen a 
visit was also paid to the northern boundar}- of the Turtle moun- 
tain, and the beds composing it were hastily examined. 
During the following winter work on the well was resumed jvith 
theassistance of grants from the Canadian government and the 
Canadian Grcological Survey, and with ver}' few exceptions speci- 
mens were kept from every five feet down to a depth of 1660 feet. 
Below 1660 feet specimens were collected at irregular intervals, 
and especiall}- wherever there appeared to the driller to be an}' 
change in the character of the rock. The work also received the 
constant attention of Dr. Selwyn, director of the Canadian survey,
