Upon my return to Houghton I met Mr. I. H. Forster, who was the agent for mines and a Senator for the State. He proposed to accompany me to the sites of those ancient workings that he had personally inspected. After passing through a forest of birch and pine trees, we reached an open space where we saw the evidences of the nature of the operations that had been executed. The direction of the trenches could be easily traced, although they were filled with earth and leaves. Several of the pits had been cleared out by the men employed at one of the new mines, and it was therefore possible to go down to the bottom of them and observe the methods of excavation. The first that I examined was twelve feet deep; from the base there ran two nearly horizontal galleries or adits, following the direction of the lode which ran N.W. and S.E. These adits were five feet wide and extended laterally about six feet. Upon the surface, near the edge of the pit, was the stump of a basswood tree, six feet in circumference, and at the opposite edge was the stump of a pine, four feet in circumference. The second pit was twenty yards from the first, and had evidently been sunk in the direction required in order to reach the same lode. It was ten feet deep. From the base there was one adit following the direction of the deposit of copper. Close to the edge of this pit was the stump of a small birch tree. Beyond this were seven other pits, from twenty to fifty yards apart, and in connection with these, there were several short trenches from two to four feet wide. The pits were discovered in 1865. Some animals were being driven along a track in the forest, when one of them straying from the path, plunged his feet deep into the ground; this was noticed, and an explorer for copper examined the place and pushed his stick down it. This led to a further search, and the hole was found to be an ancient pit. Shafts were sunk, and the result has been, that, one of the most important mines in the district was established near the spot. Upon another occasion I went with Mr. Forster to look at the trenches and pits that had been found in a more distant part of the forest. These pits were smaller than those that I had previously seen, but the trenches were frequently of considerable depth. I measured several that exceeded six feet deep. These trenches were usually in short lengths, but one of them was nearly two hundred feet long. Upon making inquiries amongst the leading men of the various copper mines that have been placed in the neighbourhood of the earlier workings, I was told that the practical miners were of opinion that these excavations were of considerable antiquity. It has, however, been proved by the condition of the things that were found in the pits that these conjectures are not well founded.
