The tunnel under the St. Clair River was lined with stone taken from these quarries. They are situated about 200 feet above the level of the station. The stone is carried in cars over a tram road, and reaches the village by gravitation.-Niagara. C. P. Ry. Quarries, Beck with Township, Lot. 12, Con. XII., Lanark Co., Ont. 61. Dolomite. .... Geological Survey. This greyish-brown dolomite is from the quarries of the Canadian Pacific Railway. It is used for window and door sills and also largely for general building purposes. The stone when first quarried is soft, but hardens on exposure. The round-house at Brockville, as well as bridges and culverts along the line of the Brockville and Ottawa Railway are built of it. Blocks 3 x 3 x 15 feet can easily be obtained.—Calciferous. The beds are from three to twelve inches thick. The stone is largely employed in the town of Pembroke, and has been used to some extent for bridges. It is bluish-grey in colour and fine-grained. An analysis of a specimen similar to that exhibited gave: carbonate of lime 83.96 per cent., carbonate of magnesia 9.29 per cent., carbonate of iron C.69 per cent., insoluble 6.06 per cent.-Chazy. Horton Township, Renfrew Co., Ont............ 116. Limestone cube. •Geological Survey. This quarry, situated in Con. II, Lot 2, is called the Renfrew Granite Quarry, probably on account of the fact that the stone is supposed to somewhat resemble granite in appearance. The stone is largely used for monuments, etc., and is capable of being turned so as to show the finest relief working. The beds, which are extensive, vary from a few inches to several feet in thickness. (See No. 41 p. 205)-Laurentian. Geological Survey. Elliot's Quarry, St. Mary's, Perth Co., Ont............. Crookston, Hastings Co., Ont....... W. Gibson, Beamsville, Ont. 772. Limestone cube. These quarries are operated in the Trenton limestone. They are well situated for shipping facilities, being connected with both C.P.R. and G.T.R. Both steam-drills and hand-drills are used, and the quarry is well equipped with machinery for handling the stone.-Trenton. B. Wright's Quarry, Hull Township, Wright Co., Que. 63. Limestone. } .Geological Survey. These quarries have been extensively worked for a long time, the beds, which are almost horizontal, having been removed over a large area for a depth of 15 feet. Blocks ten by five by three feet can be taken out. Most of this stone is used for building purposes in the city of Ottawa. The upper portion of some of the beds presents a banded structure, the lower portion being finely granular. The stone is dark-grey, easily dressed, and susceptible of a high polish and sharp tooling. The results of a series of analyses of the stone of these quarries will be found in the Annual Report of the Geological Survey for 1892-93, p. 34 R.-Trenton, Caughnawaga, Que......... 65. Limestone. ...Geological Survey. The Caughnawaga quarries are on lands belonging to the Indians, and at one time furnished large quantities of stone for the upper locks of the Lachine canal, and for those of the Beauharnois canal. Subsequently they were only worked at intervals and on a very limited scale; but at present considerable quantities of stone are being obtained from them to be used in the enlargement of the Lachine canal. The beds are from nine inches to three feet thick.-Chazy. The Trenton formation yields excellent building stone at Montreal, at Lachevrotière, nearly forty miles above Quebec and at numerous intermediate places. The best stone at Montreal is derived from a band of granular, grey, bituminous limestone, ten feet thick. The beds are from three to eighteen inches thick at the bottom, passing toward the top into a black, nodular, bituminous limestone, which is interstratified, in irregular layers of from one to three inches thick, with black bituminous shale. This grey limestone which is near the base of the formation is a mass of comminuted organic remains, consisting largely of crinoids and cystideans.-Trenton. Montreal, Que....................... 6.

Marble occurs in a number of places on the coast of British Columbia and in Vancouver and adjacent islands. Quarries have been opened in a few instances, but as yet the marble has not been extensively utilized as an ornamental stone. The colours are generally grey, often handsomely variegated. Texada Island, B.C............ 80. Paper-weight, marble, greyish-white. .Geological Survey. The marbles of Texada Island are grey, white and blotched and occur in unlimited quantity, in cliffs from fifty to eighty feet high. At Marble Cove, marble forms the shore and is found continuously to the north end of the island. A marble quarry has been worked on the north side of the cove.-Carboniferous. This material is plentiful on the line of the Canadian Pacific Railway, close to Nipigon Bay and west of Nipigon Station. It is somewhat argillaceous in composition and does not take a high polish, but would be suitable for interior work.-Cambrian. Wolf Lake, Thunder Bay, Ont......... 1010. Marble. 1009. .............................Ont. Bureau of Mines. Though not susceptible of a high polish, these marbles are rich in colour, the tints varying from a mellow grey, through deeper shades, to light pinks, purples, greens and browns. Some are banded, * some clouded, and others veined.-Cambrian. From a quarry on Lot 11, Con. II. The stone from this quarry has been Arnprior, Renfrew Co., Ont...... 73. Marble, paperweight. ......Geological Survey. In the township of McNab, near the mouth of the Madawaska, a large band of crystalline limestone is exposed. The rock contains dark bands, which are sometimes narrow and sometimes wide, producing where there are no corrugations in the layers, a regularly barred or striped pattern; when the layers are contorted, a pattern something like that of a curly grained wood results. The colours are various shades of light and dark grey intermingled with white. The dark colours are due to a greater or less amount of graphite which is intimately mixed with the limestone. The texture of the stone is somewhat coarse, but it takes a good polish. Considerable quantities were employed in the decorative work of the Houses of Parliament at Ottawa.-Laurentian.
