What reading level is Secrets of the Earth book?
To quickly assess the difficulty of the text, read a short excerpt:
The men used to placer mining soon began to frown. The digging was very hard. Worse still they often spent days and weeks making a pit, only to find less than ten cents' worth of gold in it. Some of the greenhorns found what they thought were wonderful nuggets, but older miners laughed heartily when they brought the 98 SECRETS OF THE EARTH specimens to them, and said they had discovered pyrite, or "fool's gold. " Finally some miner, tiring of digging, thought that if a powerful stream of water ...could be di- rected against the great banks of earth, the layers of soil could soon be washed away on a wholesale plan, the muddy flood diverted into sluices, and the gold easily separated and saved. This was done. Great reservoirs were built high up in the mountains, and water was brought down by means of ditches, pipes or flumes, to the scene of mining operations. The ditches and flumes poured the waters directly out upon the banks, like a stream; but the pipes had a large hose fastened to them, such as a fireman uses, with a nozzle at the other end, from which a swirling, gushing stream could be thrown any- where within reach by the miner handling the hose.
