sand with a few black grains in it. Most of the grains range 

 in size from 'm to 1 mm. in diameter. At a depth of 600 feet 

 a flow of artesian brine was struck, which ran from the top of 

 the well in a small stream to the river. An analysis of the 

 water gave the following results in parts per million :
