material from the bottom of the hole. No oil was found in this boring 
but small shows of natural gas were reported. At the contact of the 
eravel drift with the rock at thirty feet from the surface, a fine vein of 
clear water was struck and now forms a flowing well. 
Several other wells have been put down at different times near the 
St. Lawrence between River Beaudette and Coteau Landing. These 
all apparently started in the Calciferous limestone formation which is 
the surface rock of the district, but no records of the borings have been 
kept. Water was found in several of these holes. 
Further west at the village of Alexandria, a somewhat deep boring 
was made several years ago, which reached a depth of 790 feet. The 
rock at the surface is the Trenton limestone, and this apparently con- 
tinued downward to a depth of 470 feet. The underlying Black River 
formation had a thickness of 100 feet and the Chazy limestones and 
shales beneath continued to a depth of 755 feet, with a thickness of 
185 feet, when the limestone of the Calciferous was reached, in which 
the boring continued to a further depth of thirty-five feet. Salt water 
was struck in this hole at a depth of 730 feet and a second vein near 
the bottom of the hole, but no gas or oil was observed at any point. 
In 1889-90, a well was bored in the western part of the city of 
Ottawa, near Patterson’s creek, close to the line of the Canada Atlantic 
railway. This well is said to have reached a depth of 1,005 feet, but 
unfortunately the records were not fully kept for the entire distance. 
The borings commenced in the Trenton limestone, which is well ex- 
posed in the vicinity, and this rock continued downward for 310 feet 
when a bed of sandstone was reported. Below this however, limestone 
was recorded to 475 feet, in portions of which fossils were found which 
resembled certain forms peculiar to the Trenton formation. From this 
point to the bottom no definite record was kept, though the strata passed 
through are said to be bluish limestone, the age of which must be con- 
sidered doubtful. No gas or oil was found in this boring. 
A boring was also made at North Gower some thirty years ago. 
As the surface rock at this place is the Calciferous limestone and no 
record was preserved as to the depth of the hole, the results obtained 
are of no practical value. 
The boring carried on some years ago to the south of Pembroke, 
to a reported depth of 500 feet, was made presumably in granite and 
gneiss as these are the only rocks seen at the surface in the vicinity. 
For the sake of comparison it may be stated that a boring near 
Toronto passed through 550 feet of Lorraine and Utica shales, under- 
lain by 585 feet of Trenton limestone which rested upon the crystalline 
rocks of the Archean. Another boring at Clarkson, west of Toronto,
