I had fortunately arrived in time to see the blastings. Those in the great pit are the most interesting; for its mouth is so very large, that it is not necessary to descend in order to see the pit-men work; all is visible from above. This is a very peculiar and interesting sight. The pit, 480 feet deep, with its colossal doors and entrances leading into the galleries, looks like a picture of the lower world, from which bridges of rocks, projections, arches and caverns formed in the walls, ascend to the upper world. The men look like pigmies, and one cannot follow their movements until the eye has accustomed itself to the depth and to the darkness prevailing below. But the darkness is not very dense; I could distinguish most of the ladders, which seemed to me like children's toys. It was nearly twelve, and the workmen left the pits, with the exception of those in charge of the mines. They ascended by means of little tubs hanging by ropes, and were raised by a windlass. It is a terrible sight to see the men soaring up on the little machine, especially when two or three ascend at once; for then one man stands in the centre, while the other two ride on the edge of the tub. [Picture: Mines of Danemora] I should have liked to descend into the great pit, but it was too late on this day, and I would not wait another. I should not have feared the descent, as I was familiar with such adventures, having explored the salt-mines of Wieliczka and Bochnia, in Gallicia, some years before, in which I had had to let myself down by a rope, which is a much more dangerous method than the tub. With the stroke of twelve, four blasting trains in the large pit were fired. The man whose business it was to apply the match ran away in great haste, and sheltered himself behind a wall of rock. In a few moments the powder flashed, some stones fell, and then a fearful crash was heard all around, followed by the rolling and falling of the blasted masses. Repeated echoes announced the fearful explosion in the interior of the pits: the whole left a terrible impression on me. Scarcely had one mine ceased to rage, when the second began, then the third, and so on. These blastings take place daily in different mines. The other pits are deeper, the deepest being 600 feet; but the mouths are smaller, and the shafts not perpendicular, so that the eye is lost in darkness, which is a still more unpleasant sensation. I gazed with oppressed chest into the dark space, vainly endeavouring to distinguish something. I should not like to be a miner; I could not endure life without the light of day; and when I turned from the dark pits, I cast my eyes thankfully on the cheerful landscape basking in the sun. I returned to Upsala on the same day, having made this little journey by post. I can merely narrate the facts, without giving an opinion on the good or bad conveniences for locomotion, as this was more a pleasure-trip than a journey.
