What reading level is Eurasia book?
To quickly assess the difficulty of the text, read a short excerpt:
"When our mining experts discover a mineral belt containingprecious metals or copper, iron, lead, nickel, platinum, cobalt, quicksilver, manganese or any other ore used in manufactures and thearts, the first thing we do is to sink a shaft on the most likely orechimney and at every one hundred feet in depth we run levels to developit and if we continue to find ore as we go down and the ground requiresdrainage, we survey for a drainage tunnel that will drain the mine atthe greatest depth, even if... we have to run a tunnel ten miles. We sinkthe shaft to within twenty feet of the tunnel level and then quitsinking until the tunnel is completed. We use a tunneling machine, boring a tunnel six feet in diameter at the rate of one hundred feetper day. We run the tunnel directly under the shaft and then withdrawall the men and machinery from the tunnel, put a six-inch drill intothe shaft that makes a hole into the tunnel, and quickly drains themine. Then we begin to stope out at the lowest level, filling in thewaste upward, and taking out only ore to be conveyed to the mill orsmelter.
