'SS{S. Smith}' OIL PRESSURES. X. 7010
X. 7060 X. 7000

We should be glad if you would let us know
at some convenient time to what figures the various oil
pressures, high, intermediate, and low, attain when starting
from cold on the SS.{S. Smith}

We think the intermediate should reach quite
a useful pressure during the warming up period for forcing
the cold oil to the various parts of the valve gear.
