[ezzs] THE CARBONIFEROUS BASIN IN NEW BRUNSWICK 55 
Further attempts were made in the area south of the St. John River, 
on the Otnabog stream, at a point about twenty-six miles southwest of 
the last recorded. This place is near the southern side of the Carbon- 
iferous basin. The boring here reached a depth of nearly 200 feet, pass- 
ing through a mass of coarse gray conglomerate for nearly 140 feet, but 
no coal was found. It is worthy of note that no such thickness of these 
coarse beds was recorded in any of the borings in the northern portion 
of the Grand Lake basin. 
Subsequently the drill was removed to Three-tree Creek, about 
eighteen miles south of Fredericton and ten miles north of the southern 
limit of the Carboniferous basin in this direction. No official record in 
detail was kept of this boring, which reached a depth of 600 feet, except 
that a considerable ticles) of purple sandstones was traversed, and no 
trace of coal was reported. The country between this place and the St. 
John River to the north shows a succession of gray sandstones and con- 
glomerates with interstratified beds of dark or purple sandstones which 
are an integral portion of the gray series at many points throughout the 
western part of the Carboniferous basin. 
It may be presumed therefore that with the two exceptions recorded 
in the Grand Lake area or the Newcastle basin, where the underlying 
slates were reached, the rocks of the Carboniferous area have not yet 
been definitely pierced and the actual thickness of the formation has not 
thus been determined. Though the strata throughout are generally in 
a nearly horizontal position, at several points there is a well-defined 
dip of from ten to twenty degrees, so that there may be faults the exact 
location of which cannot be accurately defined, owing to the lack of good 
exposures over much of this area. 
In the eastern part of the Carboniferous area other borings have 
been made at a comparatively recent date. Among these may be men- 
tioned two holes near Moncton, one of which reached a depth of 737 
feet, the other to a less depth. In neither of these was any coal reported, 
and the rocks traversed were probably low down in the Millstone-grit 
or were in part referable to the lower Carboniferous formation. 
In 1897 boring operations were resumed near Dunsinane not far 
from the line of the Intercolonial railway. At this place five holes 
were bored, one of which reached a depth of nearly 1300 feet, though 
the others ended at a much less depth. In several of these coal was 
reported, and one seam was stated to have a thickness of three and a half 
feet. The rocks traversed by the drill comprised red and gray shales, 
and a great thickness of grayish sandstones, interstratified with con- 
glomerates, was found. These holes were located in a small side basin 
separated from the main area by a great ridge of lower Carboniferous 
rocks, and it is possible that in the deep boring the drill for the lower
