plains of Iowa county, in that part of the North-Western Territory which is attached, for the purposes of temporary government, to Michigan. It is made up of clear and permanent springs, and has a descent which affords a very valuable water-power. This has been particularly remarked at the curve called Millseat-bend. No change in its general course, which is south-west, is I believe apparent after it enters the north-west angle of the state of Illinois. The town of Galena, the capital of the mining country, occupies a somewhat precipitous semicircular bend, on the right (or north) bank of the river, six or seven miles from its entrance into the Mississippi. Backwater, from the latter, gives the stream itself the appearance, as it bears the name, of a “river,” and admits steamboat navigation thus far. It is a rapid brook immediately above the town, and of no further value for the purpose of navigation. Lead is brought in from the smelting furnaces, on heavy ox-teams, capable of carrying several tons at a load. I do not know that water has been, or that it cannot be made subservient in the transportation of this article from the mines. The streams themselves are numerous and permanent, although they are small, and it would require the aid of so many of these, on any projected route, that it is to be feared the supply of water would be inadequate. To remedy this deficiency, the Wisconsin itself might be relied on. Could the waters of this river be conducted in a canal along its valley from the portage to the bend at Arena, they might, from this point, be deflected in a direct line to Galena? This route would cut the mine district centrally, and afford the upper tributaries of the Pekatolika and Fever River as feeders. Such a communication would open the way to a northern market, and merchandise might be supplied by the way of Green Bay, when the low state of water in the Mississippi prevents the ascent of boats. It would, at all times, obviate the tedious voyage, which goods ordered from the Atlantic cities have to perform through the straits of Florida and Gulf of Mexico. A railroad could be laid upon this route with equal, perhaps superior advantages. These things may seem too much like making arrangements for the next generation. But we cannot fix bounds to the efforts of our spreading population, and spirit of enterprise. Nor, after what we have seen in the way of internal improvement, in our own day and generation, should we deem any thing too hard to be accomplished.
I set out from Galena in a light wagon, drawn by two horses, about ten o’clock in the morning (August 17th), accompanied by Mr. B. It had rained the night and morning of the day previous, which rendered the streets and roads quite muddy. A marly soil, easily penetrated by rain, was, however, as susceptible to the influence of the sun, and in a much shorter period than would be imagined, the surface became dry. Although a heavy and continued shower had thoroughly drenched the ground, and covered it with superfluous water, but very little effects of it were to be seen at this time. We ascended into the open plain country, which appears in every direction around the town, and directed our course to Gratiot’s Grove. In this distance, which on our programme of the route, was put down at fifteen miles, a lively idea of the formation and character of the country is given. The eye is feasted with the boundlessness of its range. Grass and flowers spread before and beside the traveller, and on looking back, they fill up the vista behind him. He soon finds himself in the midst of a sylvan scene. Groves fringe the tops of the most distant elevations, and clusters of trees—more rarely, open forests—are occasionally presented. The trees appear to be almost exclusively of the species of white oak and roughbark hickory. Among the flowers, the plant called rosin-weed attracts attention by its gigantic stature, and it is accompanied, as certainly as substance by shadow, by the wild indigo, two plants which were afterward detected of less luxuriant growth on Fox River. The roads are in their natural condition, they are excellent, except for a few yards where streams are crossed. At such places there is a plunge into soft, black muck, and it requires all the powers of a horse harnessed to a wagon to emerge from the stream.
On reaching Gratiot’s Grove, I handed letters of introduction to Mr. H. and B. Gratiot. These gentlemen appear to be extensively engaged in smelting. They conducted me to see the ore prepared for smelting in the log furnace; and also the preparation of such parts of it for the ash furnace as do not undergo complete fusion in the first process. The ash furnace is a very simple kind of air furnace, with a grate so arranged as to throw a reverberating flame upon the hearth where the prepared ore is laid. It is built against a declivity, and charged by throwing the materials to be operated upon, down the flue. A silicious flux is used; and the scoria is tapped and suffered to flow out, from the side of the furnace, before drawing off the melted lead. The latter is received in an excavation made in the earth, from which it is ladled out into iron moulds. The whole process is conducted in the open air, with sometimes a slight shed. The lead ore is piled in cribs of logs, which are roofed. Hammers, ladles, a kind of tongs, and some other iron tools are required. The simplicity of the process, the absence of external show in buildings, and the direct and ready application of the means to the end, are remarkable, as pleasing characteristics about the smelting establishment.
The ore used is the common sulphuret, with a foliated, glittering and cubical fracture. It occurs with scarcely any adhering gangue. Cubical masses of it are found, at some of the diggings, which are studded over with minute crystals of calcareous spar. These crystals, when examined, have the form of the dog-tooth spar. This broad, square-shaped, and square-broken mineral, is taken from east and west leads, is most easy to smelt, and yields the greatest per centum of lead. It is estimated to produce fifty per cent. from the log furnace, and about sixteen more when treated with a flux in the ash furnace.
Miners classify their ore from its position in the mine. Ore from east and west leads, is raised from clay diggings, although these diggings may be pursued under the first stratum of rock. Ore from north and south leads, is termed “sheet minerals,” and is usually taken from rock diggings. The vein or sheet stands perpendicularly in the fissure, and is usually struck in sinking from six to ten feet. The sheet varies in thickness from six or eight inches, in the broadest part, to not more than one. The great mass found at “Irish diggings,” was of this kind.
I observed among the piles of ore at Gratiot’s, the combination of zinc with lead ore, which is denominated dry bone. It is cast by as unproductive. Mr. B. Gratiot also showed me pieces of the common ore which had undergone desulphuration in the log furnace. Its natural splendor is increased by this process, so as to have the appearance of highly burnished steel. He also presented me some uniform masses of lead, recrystallized from a metallic state, under the hearth of the ash furnace. The tendency to rectangular structure in these delicate and fragile masses is very remarkable. Crystallization appears to have taken place under circumstances which opposed the production of a complete and perfect cube or parallelogram, although there are innumerable rectangles of each geometric form.
In the drive from Gratiot’s to Willow Springs, we saw a succession of the same objects that had formed the prominent features of the landscape from Galena. The platte mounds, which had appeared on our left all the morning, continued visible until we entered the grove that embraces the site of the springs. Little mounds of red earth frequently appeared above the grass, to testify to the labors of miners along this part of the route. In taking a hasty survey of some of the numerous excavations of Irish diggings, I observed among the rubbish small flat masses of a yellowish white amorphous mineral substance of great weight. I have not had time to submit it to any tests. It appears too heavy and compact for the earthy yellow oxide of lead. I should not be disappointed to find it an oxide of zinc. No rock stratum protrudes from the ground in this part of the country. The consolidated masses thrown up from the diggings, appear to be silicated limestone, often friable, and not crystalline. Galena is found in open fissures in this rock.
We reached the springs in the dusk of the evening, and found good accommodations at Ray’s. Distance from Galena thirty miles.
The rain fell copiously during the night, and on the morning (eighteenth) gave no signs of a speedy cessation. Those who travel ought often, however, to call to mind the remark of Xenophon, that “pleasure is the result of toil,” and not permit slight impediments to arrest them, particularly when they have definite points to make. We set forward in a moderate rain, but in less than an hour had the pleasure to perceive signs of it mitigating, and before nine o’clock it was quite clear. We stopped a short time at Bracken’s furnace. Mr. Bracken gave me specimens of organic remains, in the condition of earthy calcareous carbonates, procured on a neighbouring ridge. He described the locality as being plentiful in casts
