a As measured weekly by Countryman & Jaquith with current meter. 
f> As estimated by Countryman & Jaquith from weekly measurements considered in relation to dates at which prin- ■ 
eipal fluctuations occurred. 
Messrs. Countryman & Jaquith" estimate the total discharge of the tunnel 
to January 1, 1905, at approximately 3,550,000,000 gallons, equal to about 
474,695,000 cubic feet, or 10,900 “ acre-feet,” and weighing approximately 14,834,000 
tons. The same engineers estimate the minimum cost of pumping this quantity 
of water, with an average lift of 500 feet, at $600,000, whereas the total cost of the 
El Paso tunnel was $90,000. 
As was the case with the Standard tunnel, the El Paso slowly lowered the water 
in the Mary McKinney and Elkton mines, showing that there is a connection through 
a Personal letter of February 13, 1905.
