Pumping is continued through May, June and July, and the salt is ready for gather- ing in August. During midsummer the amount of water evaporated is 8,400,000 gallons daily. The yield of salt is at the rate of 150 tons per inch of water per acre. An average season's yield is a layer of salt about seven inches thick, which would be precipitated from -forty-nine inches of water. The facilities for this industry may be judged by the fact that coarse salt packed on cars ready for shipping, is sold ...at the works for one dollar per ton. The mother-liquor is allowed to go to waste, but it is to be expected that sodium sulphate and other salts contained in it will be utilized in the near future. RELATION OF LAKES TO CLIMATIC CONDITIONS. 83 Along the margin of Great Salt lake, where the water is only a few inches deep, it becomes so concentrated by evaporation that common salt crystallizes and forms a brilliant white layer on the bottom. In fording an arm of the lake about a mile broad, in order to reach Stansbury island, the writer, in 1880, found a crust of salt forming a glistening pavement strong enough to support a horse and rider, but occasionally it would give way and lead to uncomfortable flounderings in the black mud beneath.
