No. 5 of Mr. Stirling is the second largest outcrop on Limestone 
Creek. It is on the northern side of the stream, and presents a bold 
outcrop which rises 60 feet above the creek. The strike of the slate beds 
in the creek is E. 30 deg. N., and they dip N. 30 deg. W. at 60 deg. 
This outcrop is probably many acres in extent, but a proper survey would 
be required to determine its exact extent. In it there are extensive caves 
with entrances opposite the creek, through which Limestone Creek flows 
when in flood. In several places, attached to the sides of the caves, there 
are masses of conglomerate; these were formed when the floor of the 
caves was at a higher level. Gravel was washed into the cave and 
cemented into a solid conglomerate by the infiltration of calcareous 
material, and, at the same time, firmly attached to the walls aJnd 'floor 
with which it was in contact. Subsequent erosion has deepened the caves 
and left the remains of the conglomerate attached to the side, several 
feet above the present floor. 
The marble of this outcrop is of pale and darker grey, dove colour, 
yellowish-white, &c. It appears to be compact and free from fissures or 
cracks over considerable areas. This side is suitable for quarries, and 
large blocks of solid marble could be obtained. The material could be 
worked economically from the face. There is abundance of material dis¬ 
closed above water-level, and probably much more buried underground at 
this outcrop. 
A little lower down the creek there are two small outcrops (Nos. 6 
and 7 on Mr. Stirling’s map), which consist of hard bluish-grey marble, 
but they are not of much consequence. Still further down the creek 
(about i\ miles) is No. 9 of Mr. Stirling’s map. This is a much larger 
outcrop similar in character to Nos. 6 and 7, but the material is not of 
great value. 
Stony Creek Marble. 
By far the largest and most important outcrop is the deposit at Stony 
Creek. Altogether it probably covers an area of between 30 or 40 acres. 
It is divided into three portions by two bands of ash or porphy- 
ritic material. The marble is very massive, and appears to be very solid 
underneath. There is a general absence of swallow-holes and other 
indications usually present when the limestone is cavernous below. Much 
of the marble is very massive, but towards the northern end of the outcrop, 
where quarries have been opened on the eastern bank of Stony Creek, 
there is a greater tendency to bedding. 
This is decidedly the most favorable site for working the marble, as 
the quality is apparently equal to the best of the other outcrops, and, in 
addition, there is a greater variety of colour and of markings. Near the 
northern end at the quarry there are marbles with pale-pink markings, 
and also with pink and green markings. There is a wide area of dull 
yellowish-white marble on the western side, and in the central portion 
also; much of this whitish coloured marble has a reddish mottled appear¬ 
ance, .and would probably cut into a useful material. Further southward 
the marble iis greyish. 
On the extreme western edge of the outcrop there is a deposit of 
breccia, in which the fragments are red, and red and white, or white 
mottled with red. This stone has been formed by the fragments of 
original marble becoming agglutinated through infiltration of calcareous 
material. It is a handsome ornamental stone, but there appears to be 
only a few cubic yards of it. Possibly there are other similar rocks, but 
none were observed except at the one spot. 
Several hundred pounds were expended many years ago by the Pen- 
tellic Marble Company in an endeavour to utilize the marble of this
