What reading level is Ancient Mining On the Shores of Lake Superior book?
To quickly assess the difficulty of the text, read a short excerpt:
— c c. Worn obliquely.
The blades are more worn on the under side than the upper, as if the mineral had been scraped together and then shovelled out, as is the practice of the miners of the present day. The shovels which were found beneath the water level were sound in appearance, and the strokes of the tool by which they were formed remained perfectly distinct, but on being dried they shrunk very much, opening in long cracks, the wood retaining little of its original strength or hardness.
A bi...rch tree, two feet in diameter, grew directly over one of these paddles.
A portion of a wooden scoop, or bowl, was found in the pit, evidently intended to dip up and to pass water. Its edge had been worn, like the shovels, by scraping over the rock; but it was so much decayed that it fell to pieces when it was taken out.
I examined the walls of this cavern minutely, hoping to find the marks of some tool of metal. The effects of blows of stone mauls were visible, and such is the hardness of the rock, that if drills or picks had been used upon it, I think the marks would be easily seen, particularly on that part which was protected from the atmosphere by water.
