extracted from a report on the location by Professor Chapman, of Toronto

The mines were first opened during the winter of 1872-73. They are about ten miles from the city of Ottawa, and six and a quarter miles from a shipping point on the Gatineau River, with which they are connected by a well built tramway. Four Catalan forges, with all necessary accessories, have recently been erected and are now in working order.-Laurentian.

9. Jacksontown, near Woodstock, Carleton County, N.B... Geological Survey. a. Specimen of brownish-red hematite.

The iron ores of Woodstock were first discovered by the Geological Survey of the State of Maine, under Dr. Chas. T. Jackson, as early as the year 1836, having been traced by him from the Aroostook region in that state north-eastward to the St. John River, and more recently, by other explorers to the eastward of the river forming several bands extending over a considerable portion of the northern and north-eastern portions of the county of Carleton. The principal locality in which the ore has been mined is at Jacksontown, about three and a half miles from Woodstock and about two miles from the west bank of the St. John River. As seen at this point, the ore beds (portions of which are true hematite, while others consist of hydrous peroxide of iron or limonite) are somewhat irregularly interstratified with a series of clay slates, usually bright red or brownish-red in immediate proximity to the ore, but elsewhere of a pale grey colour, and highly inclined. The ore beds are from six inches to eight feet thick, the average being about three and a half feet, and their number variable. About 40,000 tons are said to have been smelted at the Woodstock works while in operation.-Upper Silurian. 10. Londonderry, N.S. ..... The Steel Company of Canada, (limited.)

a. Specimens of specular iron ore. From near the west bank of Cook's Brook, where a level was many years ago driven for a distance of 150 yards. The vein is said to have been reached at a distance of fifty yards from the mouth of the level, and to have an average thickness of from three to four feet. An analysis of a specimen of the ore gave the following results (Rept. Geol. Survey, 1873-74, p. 224)

Although this ore is but a short distance from the Londonderry furnace, but little has been smelted, probably on account of its being more difficult to reduce than the limonite.-Upper Silurian.

These specimens are from an important deposit of ore occurring on the west side of the East River, in slates and quartzites of Upper Silurian age. The lode, so far as examined by Mr. Edward Gilpin, F.G.S., the engineer in charge, ranges in thickness from ten to twenty feet, with occasional side veins. From a single pit which was sunk to a depth of thirty feet on the lode, about fifty tons of ore were obtained. A specimen examined by Dr. T. E. Thorpe of the Andersonian University, Glasgow, contained,

The proximity of the Pictou coal field adds greatly to the value of this and other deposits of ore in the vicinity of the East River.-Upper Silurian.

a. Specimens of red hematite.

From what is known as the "Great Red Hematite Bed of McLellan's Mountain," an interstratified bed of ore occurring in slates and quartzites. The following analysis of a specimen of the ore is by Dr. Stevenson MacAdam of Edinburgh:

The ore has been traced completely across Right-to-work No. 8, and found to vary in width from fifteen to thirty feet, the angle of dip ranging from 25° to 75°. The specimens are from about the centre of the area, where a section showed fifteen feet four inches of ore of uniform quality.-Lower Helderberg formation, Upper Silurian.

a. Specimen of red hematite.

Matheson & Gillis, Sydney, C.B.

From a bed of ore about eight feet thick, occurring in hard felsitic rocks and soft nacreous and steatitic slates. The ore has been traced by a series of openings along the strike for a distance of seven hundred yards. The property is situated about twenty-four miles from Sydney, and is on the eastern shore of Bras D'Or Lake, an arm of the sea affording excellent harbours. In the event of smelting operations being carried on, coal could be easily obtained from Sydney, and the forests in the vicinity of the ore-bed would afford an abundant supply of wood for the manufacture of charcoal. According to Professor How of Windsor, N.S., the ore contains 61.39 per cent. of iron, and only traces of phosphorus and sulphur. On the opposite side of East Bay, and at Whykokomagh, somewhat similar ores occur in abundance, associated with beds of crystalline limestone.-Huronian?

A bed ninety feet thick occurring in anorthosite rock. The ore contains over forty per cent. of titanic acid and about thirty-seven per cent. of metallic iron. In some parts of the bed orange-red grains of rutile are disseminated through the ilmenite In 1873 two blast furnaces were erected near Bay St. Paul by the Canadian Titanic Iron Company, and attempts made to smelt the ilmenite with charcoal; but although good pig iron was produced, the enterprise was soon abandoned, owing to the enormous consumption of fuel. Under the most favourable circumstances from 190 to 237 bushels of charcoal were required to make a ton of iron, while in some cases over 400 bushels were consumed. The blast furnaces are forty feet high, fourteen feet in diameter at the boshes, eight feet at the throat, and four feet at the hearth. Both they and their accessories are built in the most substantial manner.-Laurentian.

Bog iron ores are of common occurrence in the Provinces of Quebec and Ontario, more especially in the sandy tracts which often flank the Laurentian hills. The variety employed for smelting occurs in concretionary masses which are either dull or earthy, or at times highly lustrous when fractured. The colour is usually yellowish-brown, and dark brown or black when much manganese, is present. The concretions are scattered through the soil, or else form patches or continuous layers which are sometimes several feet thick, though generally only a few inches. The specimens analyzed contain an average of fifty per cent. of iron, but the yield in the furnace is generally only thirty to forty per cent., owing no doubt to the difficulty of freeing the ore from sand. The blast furnace at the "St. Maurice Forges" was built as early as 1737, and is the oldest one in Canada. The fuel employed is entirely charcoal, and the flux limestone from the Trenton formation. The usual charge is bog ore 600 lbs., limestone 45 lbs., charcoal 16 bushels (the minot=2250 cub. in.) weighing 11 to 12 lbs. to the bushel. The pig iron is shipped to Montreal and there manufactured into car wheels, for which long experience has shown it to be well adapted. Small quantities of wrought iron are also made in a hearth-finery. The manufacture of axes has recently been discontinued. At L'Islet, about four miles from the St. Maurice, there is another blast furnace, also owned by the Messrs. MacDougall.-Alluvion.

Bog ores similar to those occurring near the St. Maurice Forges are found in the vicinity of the St. Francis River south of the St. Lawrence. In 1869 a blast-furnace was erected for smelting them, at Rivière aux Vaches, by the St. Francis River Mining Company, and in the ensuing four years between five and six thousand tons of pig iron were made, about half of which was white and mottled. The ore yielded on an average about thirty-six per cent. of iron. In 1873 the furnace was sold to John McDougall & Co., of Montreal, who make use of the iron produced in the manufacture of car wheels.-Alluvion.

... Geological Survey.

In the seigniory of Vaudreuil, at the confluence of the rivers Ottawa and St. Lawrence, bog iron ore is found in many localities, but appears to be most abundant in Côte St. Charles, where in one place a bed is said to attain a thickness of eight feet. In Ste. Angelique, on what is known as the McGillis property, and also in Ste. Elizabeth, the ore occurs in the form of brownish-black concretions averaging about three-quarters of an inch in diameter and containing a large proportion of oxide of manganese. An analysis of this variety gave as follows:

The specimen exhibited is from Côte St. Charles, where the ore generally contains over fifty per cent. of iron, and but little manganese.-Alluvion.

Geological Survey..

Deposits of bog iron ore, of greater or less extent, are not of unfrequent occur rence in New Brunswick, the largest as well as the purest beds being found in alluvion overlying the rocks of the coal measures in Queens, Sunbury and York. counties. They are in some cases known to cover considerable areas, and to attain a thickness of several feet, but no attempt has hitherto been made to utilize them. A sample from the parish of Burton, in Sunbury county, was found to contain 47 per cent. of iron. Bog ores also occur in Nova Scotia, and small quantities have been smelted at Clementsport in Annapolis county.-Alluvion.
