What reading level is Gold Mines of Beauce: Accompanied By a Topographical Map book?
To quickly assess the difficulty of the text, read a short excerpt:
When a considerable space has been dug out the wheeler brings to the tubs only the pieces of the bed rock and about one foot of the gravel which lies on the bottom and is the best alluvion ; he then fills the vacant space with the larger stones and the superior gravel, reputed to be poor.
The miners use, to have light under ground, tallow candles, because these candles can be moved more easily than oil lamps. Besides, the water which filters con- tinnally from the vault of the galleries, and th...e very little air in the mine, would render the use of ordinary lamps impossible. The electric lamp only could be used.
There is now in the north bank of the Gilbert a list of ground 9000 feet long and 200 wide crossed on all sides by tunnels, real catacombs that extend every day and are very interesting to see.
Several methods are employed in washing gold, but the most used in these mines are those called hydraulic process, sluice and the puddling machine.
Mr. William P. Blake, in a report on the gold mines of Q-eorgia, described the hydraulic process, and the following is the translation of his descriptioaj^f^was published in the Report of Progress for 1863.
