induced by lateral pressure, helps to conceal the bedding. But a controlling feature of the
structure is shown by the attitude of the conglomerate, which is plainly indicated by the logs.
Hole No. 1 (Post 8, Report 1920): Altitude, 0 feet; depth to conglomerate, 770 feet.
Hole No. 2, 1,600 feet N. 60° E.: Altitude, —23 feet; depth to conglomerate, 1,080 feet.
Hole No. 4, 4,700 feet N. 30° W.: Altitude, 4-92 feet; depth to conglomerate, 1,100 feet.
Hole No. 5, 6,800 feet S. T4° W.: Altitude, +200 feet; depth to conglomerate, 1.118 feet.
These four holes thus indicate a dome structure in which the strata dip north-east, north-
west, and south-west away from hoje No. 1, where the structure is practically horizontal as is
shown at the surface. - (See diagram.)

Hole No. 3 was drilled more than a mile east of No. 2 in order to test the St. John formation
at a higher horizon, and also to try the ground beneath the prominent chain of hills already
mentioned which parallels the foot-hills for some 20 miles in this district. A depth of 2.035 feet
was reached. The core is almost entirely dark shale of the St. John type and rarely shows a
dip of 3°. No conglomerate was found. But near the bottom, especially below 1,990 feet, the
sandstone takes on the general character of the Bullhead, and possibly, if not probably, marks
the top of that formation. In any event no upward folding of the Bullhead in this direction is
indicated by this core, and a gradual thickening of the St. John still continues towards the east.
The hills, therefore, no not appear to offer favourable structure at this point, or the St. John to
earry oil in useful quantity.

CHEMICAL TESTS.

Hight samples of rock taken from different parts of the cores where traces of oil were
reported were submitted to J. T. Donald & Co., Chemists, Montreal, for distillation tests. No
oil was found.

The character of the coal was next considered. The proportion of carbon in the coal of a
district, in the absence of oil, affords the best available indication as to whether or not oil may
exist in the locality. This had been previously tried with two samples of coal from the first
hole and a neighbouring locality. But the samples were not representative and the results were
conflicting and in a measure misleading. Accordingly two samples were taken from the fifth
