THE DAILY UNION.

The ordinary safety valve has heretofore and BY
many deemed sufficient to guard against pressure

the case and susceptible of mathematical proofs if
figures tedious and beyond the capacity Of the ordinary
practical engineer let him make comparison with high head
Of steam sufficient TO raise the valve with fierce fire. and the
result will be- that notwithstanding the valve doing much

for this seeming naccuracy ii Is rational to conclude
this must proceed from rapidly accumulated steam

thus accumulated excessive pressure be produced other

weighing but, unfortunately, we, without reflection, in

This Is natural; for ninety nine Of hundred have taken
