"rerms Of Water Measurement for
Mining, Irrigation and Mill Power"
II sayG The designation Of the terms
Of water measurement seems 70 be
somewhat misunaefstood, or has be-
come misleading In many parts q the
UnitedSlates from themanner To which
primitive custom Of water measufe'
ment has been adopted In different To-
calluea and ailetwarI In some Of IT,
forms been made legal by the courts.
Differences In elevation above the
sea and the latitude make a slight
difference In the dow Of water by
gravity for length Of time, too small
for practical consideration, but lust
enough for legal quibble when water
