GAS AND GAS METERS.

the pressure little by little, in order to compensate for the increased 

 loss due to increased flow through the mains. At 6.15 p. m. (B), the 

 works ceased increasing the pressure. While this increase lasted — 

 from 6.15 r. M. (B) to 10.15 p. m. (C) — our friend near the works 

 suffered under twenty-one tenths pressure, the gas blowing merrily 

 through the tips and the meter conscientiously registering gas wasted 

 as well as gas utilized. From 10.15 p. m. (C) the pressure falls by steps 

 during the ensuing two hours, finally reaching eleven tenths just after 



midnight (D), which latter pressure is quite steadily maintained until 

 the following forenoon. The service from bedtime to dinner time 

 should have proved quite satisfactory. One would naturally expect 

 to find this consumer complaining of high bills, however. 



Visiting the fellow at the distant end of the line, we find conditions 

 widely at variance from those already considered. Exhibit 2 tells a new 

 story. The recording gauge was placed in service at 4 p. M. (E), and 

 shortly afterward (A), the pressure began to fall. The jets grew 

 dimmer and dimmer, while the Welsbach mantles became petticoats of
