Part 13 (2/2)

Governor Semple, in his report for 1887, gives as the total s.h.i.+pment for the year ending June 30, 1887, the amount 525,705 tons. And he gives as the total output of coal from all the Was.h.i.+ngton Territory mines from the beginning of s.h.i.+pments to June 30, 1887:

MINES. TONS.

I have now given a sketch of all the coal mines and coal areas of Was.h.i.+ngton Territory, and will conclude with a few words on the coal of Vancouver's Island.

[Sidenote: Coal on Vancouver's Island.]

_g._ _Coal Seams in British Columbia._ The productive coal field is on Vancouver's Island, on the east side of the Gulf of Georgia. There are three mines in operation as given below:

This coal is marketed chiefly in California. The coal is lignitic; and yet it is said to c.o.ke well. It is also good stocking coal. The beds dip from 5 to 30 southward. The cost of transportation to San Francisco is about the same as from Seattle, and the cost of delivering on board s.h.i.+p about the same as from the Newcastle mines. The tariff of 75 cents per ton on foreign coal is regarded with satisfaction by the coal men of Was.h.i.+ngton Territory. The repeal of this tariff would inflict a heavy blow upon the mining industry of the Territory.

[Sidenote: The Iron Ores.]

II. IRON ORE.--The iron ores of Was.h.i.+ngton Territory consist of Bog ore, Brown ore (Limonite), some Red, or Specular ore (Hemat.i.te), and Magnetic ore (Magnet.i.te). The bog ore has been found in considerable quant.i.ties underlying the flats bordering Puget Sound, and has been worked in a furnace on Bellingham Bay. These ores, no doubt, come from the decomposition of the limonites, the magnet.i.tes and the basaltic rocks of the high lands, especially on the Cascade Mountains. These Bellingham Bay ores generally have an excess of phosphorus, and yield about 42 per cent. of metallic iron. Brown ore is reported on the Skagit River, sufficiently abundant, perhaps, but not containing more than 40 per cent. metallic iron. I saw a remarkable deposit of brown ore on the Willamette, near Portland, Oregon. It is a horizontal stratum varying from 4 to 20 feet in thickness, lying between ma.s.ses of basalt. It has been worked in the Oswego furnace, but yielded only about 40 per cent.

metallic iron. I did not see any specular ore in place in Was.h.i.+ngton Territory, but saw samples, said to have been brought from near the Middle Fork of Snoqualmie River.

[Sidenote: Resembles the Cranberry ore deposits.]

But unquestionably the most important, as well as the largest, are the magnetic ore beds on the Cascade Mountains. These ores are found 1,000 to 1,500 feet above the chief water-courses on those high ridges and peaks which make up the Cascade Range along the headwaters of the Snoqualmie, on the west side of the mountain, and of the Yakima on the east flank of the mountain. These ores are underlaid by syenite and quartzite, and overlaid by limestone. The ore itself is found in conditions similar to that of the Cranberry ore in the Unaka Mountains of North Carolina; that is, it lies in pockets of various sizes in hornblendic, porphyritic and epidotic rocks.

[Sidenote: Guye Mine on Mount Logan.]

I visited two exposures of this ore, one on Mount Logan and the other on Mount Denny. These are only a mile or two from the line of the railroad.

On Mount Logan there was only one large outcrop of iron-bearing rocks, but float was seen at numerous points on the mountain. The main exposure showed an ore-bearing rock, presenting a horizontal front some sixty feet in length, and forty to fifty feet in height or thickness. At one place a considerable area in this s.p.a.ce seemed to be pure ore. For the rest, the pockets were smaller, and, of course, the amount of rock proportionally larger. What is to be found on going in from the surface can never be told in advance in ore beds of this sort. In working the great mine of Cranberry, North Carolina, the largest body of ore was reached 100 to 200 feet from the surface.

This bed of ore is known as The Summit, or Guye Mine. Its elevation is 1,250 feet above the grade of the Lake Sh.o.r.e Railroad, and about 1,000 feet above the small stream at the foot of the mountain. There would be no difficulty in building an inclined plane from the ore bank to the small valley below. The snow in winter might interfere with mining.

Ascending the mountain above the main exposure, I found what seemed to be another level of iron ore 100 feet higher; but possibly it may be the same bed displaced. Still higher appeared to be a third level of ore, and higher still, I observed a little float ore at a point nearly 2,000 feet above the grade of the railroad, on what may be called the summit of Mount Logan, at a point which my barometer made 4,700 feet above Puget Sound.

[Sidenote: Denny Mine.]

The Denny Mine is on a different mountain, somewhat farther to the west, but about the same distance from the railroad. It is reached also by a narrow valley from which a steep ascent of nearly 1,100 feet is made to the main exposure, which shows an edge of pure fine-grained magnet.i.te, about twenty feet thick, with limestone above, and also beneath, apparently. Fragments of epidote, porphyry and flinty quartzite lay around. The limestone did not show so large here as on Mount Logan. The ore dips steeply toward the south, and seemed to encrust the mountain for a distance of, perhaps, 225 feet, but with a somewhat broken surface. It then pa.s.sed with its limestone under quartzite cliffs which crest the mountain. The bed might have been followed around the mountain, where it is said to show at a number of places. It seemed to pa.s.s into a matrix of chert.

[Sidenote: Chair Peak, or Kelly Mine.]

I did not visit the Chair Peak, or Kelly Mine, which is some miles distant; but I conversed with probably every man who ever saw it, some half a dozen, including Mr. Whitworth, who made a survey of the property. It is reported as probably the largest and purest of all the deposits of magnetic ore, and lies at about the same height on the mountains. This ore would come out by way of the Middle Fork of Snoqualmie.
