116 SWEETENED CONDENSED MiLK—SEALING 
interior of each cell is partitioned off with heavy cotton wicking 
This wicking absorbs the gasoline by capillary attraction. The 
air, passing through the fine meshes of wicking, comes in contact 
with a large surface of gasoline. 
The following are some of the essential points to be observed 
in the installation and operation of gas generators of this type: 
Sink the carburetor low enough (three to five feet below the 
surface of the ground if necessarv) to permit the gas pipe to slant 
from the factory to the carburetor. If the gas pipe is horizontal, 
or inclined toward the factory, condensation water may collect 
in the pipe, obstructing the free passage of gas. ‘This causes the 
gas either not to be available at all, or to reach the stoves in 
irregular gusts, which is equally unsatisfactory. \Where the gas 
pipe slants toward the carburetor, the condensation water flows 
back into the carburetor, causing no chbstruction. Use gasoline 
of the best quality only. Cheap grades form a residue and clog 
the generator. The gasoline is best bought in iron barrels; this 
prevents unnecessary loss by evaporation, which occurs in 
wooden barrels, especially in summer. The cells should not be 
filled more than two-thirds full; too much gasoline reduces the 
yas-generating capacity of the carburetor. If, during extremely 
cold weather, the carburetor refuses to generate gas, the injection 
of a pint of wood alcohol through the blow pipe into the cells, 
usually remedies the trouble. The gas plant and gasoline storage 
should be located in a separate building and at a reasonable 
distance from the main building, in order to minimize danger 
from fire.
