In Table XVI are recorded the results of some analyses of material 

 which do not readily fit into the classification previously recorded. Some 

 of these samples contain appreciable quantities of soluble salts, while 

 others do not contain material quantities. Thus, No. 267 and 266, rep- 

 resentatives of the limestone deposits above the Cretaceous sandstone, 

 contain only nominal amounts of soluble salts and are comparable with 

 the country of the Quaternary deposits of Cache Valley. Other samples, 

 such as No. 45 and 28, which possibly ought to be classified with the Ter- 

 tiary material, contain appreciable quantities of alkali salts. 



As an average of all determinations, this material contains 1,444 

 pounds of calcium bicarbonate, 4,535 pounds of calcium sulphate, 

 5,495 pounds of magnesium sulphate, 2,438 pounds of sodium sulphate, 

 and 3,360 pounds of sodium chlorid — that is, 0.86 per cent of the ma- 

 terial is soluble in water. 



SUMMARY OF RESULTS 



The results of these investigations show a marked amount of water- 

 soluble salts or alkali in the undistributed country rock with local 

 accumulation wherever the movement of the underground water has
