The following is an analysis of a specimen of the coal by Professor How, of Windsor, N.S.

According to Mr. G. Buist, manager of the Halifax Gas Works, the yield of gas (8 candles) is 8200 cubic feet per ton (2240 lbs.) of coal.

Caledonia Colliery, Little Glace Bay, Dominion Coal Co., Glace Bay, Cape Breton Co., N.S.

11626. Bituminous coal.

N.S.

The Dominion Coal Co. works the Caledonia colliery and eight others, all in the Sydney field. The total output of this company amounts to 50 per cent. of the production of Nova Scotia. It was incorporated in 1893, the authorized capital being $18,000,000, and controls an area of some seventy square miles of coal lands, under a lease which gives a tenure of the mining rights for a period of ninety-nine years.

The collieries of the Dominion Coal Co. are equipped with the most modern machinery, coal-cutting machines and underground endless-rope haulage being installed in all of them. They are not "fiery," naked lights being used in every case.

The Caledonia colliery is situated one mile from Little Glace Bay. The seam worked has a thickness of seven feet, and is reached by a shaft 185 feet vertical depth and two slopes 2300 and 2500 feet long respectively. The yearly output is about 300,000 tons.

Dominion No. 1 Colliery, N.S.............Dominion Coal Co, Glace Bay, N.S. 1162c. Bituminous coal.

This colliery is situated some ten miles from the town of Sydney. The seam worked has a thickness of 8 ft. and a dip of 1 in 14. The output is about 270,000 tons a year.

Reserve Colliery, Bridgeport, N.S....... Dominion Coal Co., Glace Bay, N.S.

The Reserve Colliery is the largest producer of the mines of the Dominion Coal Co., the yearly output being over 300,000 tons. The seam worked is 8 ft. 8 in. thick and is worked by two slopes of 5000 feet each.

International Colliery, Bridgeport, Dominion Coal Co., Glace Bay, N.S.

N.S.

1162. Bituminous coal.

The seam worked at the International Colliery is nearly six feet thick and is reached by a slope 4000 feet long. The yearly output of this mine is some 130,000 tons.

The seam dips S. 84° E. at an angle of 5°, and the coal has a regular cleat running N. 75°-80° W.

Hub Colliery........

1162a. Coal.

The seam worked at this place is about 12 feet thick. The annual production of the mine is about 115,000 tons.

Stellarton, Pictou, N.S..........

886. Bituminous coal.

.....Acadia Coal Co., Stellarton, N.S.

The Pictou coal-field, which occupies the centre of Pictou county, has an area of productive measures of about 25 square miles. It is eleven miles long with a maximum breadth of three miles. Its extent is therefore small, but some of the seams are of great size, one being 38 feet thick and another 40 feet. The district is remarkably intricate in structure, being cut up by numerous faults of various magnitude, and the productive measures are almost completely surrounded by a girdle of faults.

The field is very well situated for railway connections. It is conveniently divided into three sections, viz., the central or Albion, the western or Westville, and the Vale or eastern.

In the Central four seams have been worked. They are: the Main, 38 feet thick; the Deep, 22 to 40 feet; the Third, 10 to 13 feet; and the McGregor, 13 to 20 feet. The measures containing these seams rest

conformably on the Millstone Grit and are overlain by 1000 feet of shales. The dip of the coal-bearing measures varies from ten degrees to over thirty.

The following analyses are by Professor How, of Windsor College, N.S.:

The Westville section is separated from the Albion section by a downthrow fault, proved to be at least 2600 feet. The seams of this section are believed to be equivalent to some of the Albion section.

The Vale section is different in character. It is in the form of a syncline with east and west axis. The thicker and more valuable seams appear on the southern outcrop, where they are worked. On the northern side they thin out.

The Pictou field is worked mainly by two companies. The Acadia Coal Co., which operates the Acadia colliery, the Albion colliery, and the Vale colliery, and the Intercolonial Coal Mining Co., which operates the Drummond colliery. In the air-shaft of this last mine a section shows eighteen feet seven inches of coal, with an included parting of three inches of fire-clay. An analysis of coal from the upper bench, six feet from the top of the seam and directly under the clay parting, gave, according to Mr. Broome :

The mines of this district are "fiery." At all the collieries very complete ventilation plants have been put in, and safety lamps are in use.

Acadia Coal Co., Stellarton, N.S.

This colliery is situated six miles east of New Glasgow. The seam is reached by a slope 3100 feet long. The Acadia Coal Co. also operates two other collieries in Pictou county.

An analysis of a specimen from the eight foot seam of the Vale colliery gave:

The Cumberland field is the most westerly of the coal districts of Nova Scotia. There are two coal producing areas. One being at Springhill, and the other situated near the coast about fifteen miles to the west of the first. The latter may be called the Joggins coal-basin.

The exact equivalency of the measures in these two coal-basins has not yet been determined, although they are closely related. The Springhill basin is the more important producer of the two. Three workable seams have been recognized in it. All operations in this basin are carried on by the Cumberland Railway and Coal Co., by three slopes, two of which are 2600 and the third 3000 feet long.

The seams are not very "fiery," but since the explosion of 1891, safety lamps have been used.

The average of four analyses made by the late Mr. E. Hartley gave for the coal of the "Black" seam, which has a thickness of eleven feet :

In the Joggins area several seams of workable thickness, ranging in size from 24 to 6 feet, are known. The most important producer of this area is the Joggins Colliery, operated by the Canada Coal and Railway Co. The colliery is connected with the line of the Intercolonial Railway by a branch eleven miles long, and with the Joggins wharf, on Chignecto Bay, by a tramway one mile long.

The seam worked shows 4 to 5 feet of coal, with a clay parting in the centre from 1 to 3 feet, making a total thickness of from 6 to 8 feet. This is worked by two slopes, 2700 and 1900 feet respectively, which are connected. Several of the other seams have been opened and worked, some to a considerable extent. At present three or four other collieries, including the Chignecto Colliery, turn out a certain amount of coal.

The two other coal-fields in Nova Scotia, viz., the Inverness coal-field and the Richmond field, are very subordinate in importance. Only at one point are operations conducted on any scale. This is at the Broad Cove Mines, by the Broad Cove Mining Co. The greater part of the work has been put on the construction of railway connection, and the opening of a channel between the mine and the sea. Four levels have been run on the largest seams, and small shipments have been made.

Anthraxolite.

Sudbury District, Ont.....

245. Anthraxolite.

Geological Survey.

This deposit of carbonaceous material is situated on Con. I., in the township of Balfour, seventeen miles west of Sudbury, and one mile and a quarter south of the Canadian Pacific Railway. The coaly material occurs in an irregular vein in black slate. The vein is exposed for a length of 70 feet, and is 6 to 9 feet wide. A diamond-drill hole sunk for exploration, found the vein at a vertical depth of 100 feet. The material may be burnt like anthracite, but the residue of ashes is very great. This fact, together with the irregularity in its mode of occurrence, renders it of little economic importance.

230. Albertite.

This remarkable mineral, occurring in connection with Lower Carboniferous calcareo-bituminous shales, was first discovered by accident about the year 1850, and has been by some regarded as a true coal, by others as a variety of jet, and by others again as more nearly related to asphaltum. It resembles the latter closely in appearance, being very black, brittle and lustrous, with a broad conchoidal fracture and like
