pays more than the cost of producing the oil. In a gas district this is im- 
practicable. The product of many wells is gathered into one line, so long 
as the pressure is sufficient. When the pressure in any one falls below the 
standard necessary for purposes of transportation, that well must be turned 
off. Its product can not be transported separately, 1 and unless it can be used 
near by, it is valueless. (Pennsylvania Supreme Court : McKnight versus 
Manufacturers Natural Gas Co., 146 Pa. St., p. 185. ) 
DRYING NATURAL GAS. 
Natural gas as defined on page 10 is made up of a mechanical 
mixture of condensible vapors and permanent gases ; the condensible 
constituents consist of gasoline vapor and water vapor. In the 
transmission of the gas, due to changing temperature and pressure 
1 Gas compressors can, of course, he installed so as to increase the pressure of the 
gas to permit its delivery into a line. The operating cost of this, however, may he 
much more than the market value of the gas. This, of course, is a very pointed illustra- 
tion of the fundamental fact that in order to make gas conservation possible it must 
be made worth saving.
