What reading level is Report of Dr. T. Sterry Hunt ... On the Gold Region of Nova Scotia book?
To quickly assess the difficulty of the text, read a short excerpt:
In the Waverley district the mill of Mr. Biirkner has twenty-four stamps, and that of the De Wolf Company sixteen, arranged in four batteries of four each. The dura- tion of a stamp mill, and the regularity of its work, depends, in part, upon the solidity of its base ; and I may remark, in passing, that the last mentioned mill, erected under the supervision of Dr. Krakowitzer, is peculiarly well constructed in this as in other respects, and has a foundation built of granite, from which it resul...ts that the trembling motion so apparent in many stamp mills, is scarcely perceptible in this. " " The stamp mill of the Ophir Company, in the Renfrew district, recently constructed by Mr. Peter Monteith, is particularly worthy of mention. The stamps, which are round, rotating, and shod with steel, present many advantages over square non-rotating cast iron stamps. It is maintained that the effect of a round stamp, which preserves in falling the rotatory motion communicated to it during its upward movement, is much greater than that of a square stamp falling without that motion.
