CONDITION OF WATER IN BELT OF CEMENTATION.

unfavorable assumption to holding the water as a liquid), the water would 

 be a liquid in the belt of cementation, as is shown by the following table 

 based upon this supposition, column (1) being temperatures, column (2) 

 being pressures necessary to bold water as a liquid at these temperatures, 

 column (3) being depth in meters at which the pressures would be pro- 

 duced, column (4) being the depth which would be required to produce 

 the temperatures on the supposition that the increment of the increase of 

 temperature is 1° C. for every 30 meters, and column (5) being the actual 

 temperatures which exist upon this supposition at the depths represented 

 by column (3). 



Relations of pressures, temperatures, and depths in ground water.
