IRON ORE.
Handling the iron ores.The question here respecting iron ores along this road is not as to their quantity, or quality, or as to their utilization, but only as to what road or roads will handle the business that will arise from this source. Naturally the bulk of it belongs to the Seattle, Lake Shore and Eastern Railway, and at one time there seemed to be no doubt that large iron-works would at once be established at Salal Prairie by the Moss Bay Company, of England; but the east shore of Lake Washington has finally been settled upon for the great plant of this wealthy company; which of itself will go far to establish the natural monopoly which the Lake Shore Railway seems to have of the ores on the west side of Cascade Mountains. And in regard to the magnetic ores generally, this road, from its location, would seem to be master of the situation. All the iron ore on the west side of the mountain is owned by men whose interests are identified with Seattle, and with this line of railroad.Furnace sites The best point for manufacture in itself considered, the best chance for fuel, the best line for transportation, the best point for trading and for shipment, are all on the line of the Seattle Railway. Good furnace sites may be found at many points, but Salal Prairie is a spot which seems to have been set apart by nature for a manufacturing town.Salal Prairie. It lies near the intersection of the valleys of the South Fork and Middle Fork branches of Snoqualmie River, is about six miles long and three miles wide, is flat, dry, salubrious, and well supplied with water. It has a natural outlet to the South, as well as to the east and west, is convenient to the iron ore and limestone of both the Middle and South Fork, and not far distant from the ores of Cle-ellum. It is less than ten miles from Snoqualmie coking coal,Charcoal cheaply produced. and fifteen miles from the Green River coals. And, what I think is a still better resource for fuel, it is in the midst of the great Snoqualmie forests, where saw-mills will soon be felling the timber, and providing an endless supply of slabs and refuse tree-tops, from which charcoal could be manufactured at very small expense.
It is well known that charcoal is the best of all fuels for making iron, because of its freedom from damaging impurities. Its expensiveness generally prevents its being much used now, but here the cost need not exceed five cents per bushel, and 100 to 120 bushels would suffice for a ton of iron. The only question concerning the charcoal made from fir timber is as to its ability to bear the burden in a tall stack. It is becoming common now to utilize the by-products of wood, formed during its conversion into charcoal, by a process which makes the charcoal stronger. But all difficulty on this point can be relieved by conforming the size of the furnace-stack to the strength of the charcoal. This is the only fuel which has ever been used on the Pacific coast for the smelting of iron ores. These enterprises have not been particularly successful thus far, rather because of the inferior quality of the ore, than from any defect in the fuel. The bog ore and the limonites which were used at Irondale, near the Canada line, and at Oswego on the Willamette, were generally low in iron and high in phosphorus, and the bog ores were soon exhausted.
Quantity of charcoal to the ton of iron.At Irondale, near Port Townsend, recourse has been had to a refractory ore obtained on Texada Island, in Victoria Sound, on which a duty of seventy-five cents a ton has to be paid, and which requires a large amount of fuel for smelting it, perhaps as much as 150 bushels of charcoal. But Mr. H. T. Blanchard, who is interested in the Irondale Works, says in a late letter (November 29, 1887):
"It is perfectly safe to rate charcoal at six cents per bushel, and the quantity necessary to make a ton of pig-metal not to exceed 120 bushels, with a good chance of getting it down to ninety bushels per ton with fair ores."
The iron ores of the Cascade Mountains will be taken to some extent to mix with the inferior ores near the coast, but they will be chiefly worked into Bessemer-pig and steel rails.Bessemer ores commonly distant from fuel. Steel-making ores are not common anywhere, and are widely separated from fuel, which makes them very costly in the States east of the Rocky Mountains. This well-known fact is alluded to by Mr. Swank, in his report on the Iron Trade of 1886, in the following words:
"It is also a fact worthy of notice, for which geologists may find a reason, that nowhere in this country are our best steel-making ores found in proximity to mineral fuel, either anthracite or bituminous, while in some parts of the Lake Superior region, even timber suitable for the manufacture of charcoal is almost wholly wanting."
High cost of Lake Superior ores.The most important deposits of steel ores in the United States are on Lake Superior and in Missouri; but these ores are smelted chiefly by the Connellsville coke of Pennsylvania, which is 700 to 800 miles distant. The Cranberry ores of North Carolina are some hundreds of miles from fuel. A late number of the Iron Trade Review quotes the prices of ore at Cleveland, Ohio, the principal receiving point of Lake Superior ores, as follows:
| Specular and Magnetic Bessemer, | per ton | $7.00 to $7.50 |
| Bessemer Hematites | " | 5.75 to 6.70 |
Cost of producing ore in Pennsylvania.The same authority gives the cost of the ore and coke necessary for the production of a ton of iron in Mahoning Valley district, at $9.90 for the ore and $4.50 for the coke = $14.40. To this must be added about $4.25 for flux, labor, management, interest and repairs, making a total of $18.65 as the cost of producing one ton of pig-metal.
Cost of Bessemer-pig in Snoqualmie Valley.Thus the superior advantages of the Snoqualmie Valley are readily seen. Here are steel ores, two kinds of fuel, and the limestone in close proximity. Putting the fuel at more than I think it would cost; putting the cost of mining the ore at the maximum cost at Cranberry, N. C., and freight at double price, and we have as the cost of a ton of Bessemer-pig, as follows:
| Ore | $3 00 |
| Fuel | 6 00 |
| Flux | 50 |
| Labor and management | 2 00 |
| Interest and repairs | 1 50 |
| $13 00 |
This is lower than the present cost of producing Bessemer-pig anywhere in the United States, according to the best of my information; and at the same time the market is better.Large market for steel rails. The demand for steel rails in the Rocky Mountain country and in the Pacific States is, and will be, large and permanent, while the demand in China and other foreign countries will constantly increase. And so will it be with machinery and tools of all kinds, agricultural, mining and manufacturing. This demand will be both domestic and foreign, and constantly enlarging. And it may be safely asserted that no railroad exists, or can be built anywhere in the Pacific States, which will compare with the Seattle, Lake Shore and Eastern Railway in its control of the iron business.
