6 in. fans, three being stationed in each
stokehold. The electric lighting machinery consists of three dynamos

The Blake had her steering gear tested on Tuesday, Nov. 17. With both
engines going full power ahead and turning to starboard, with her helm
hard over 35 deg., she completed the circle in 4 min. 40 sec., the
port circle being completed in 5 min. 5 sec. The diameter was
estimated approximately to be about 575 yards. Forty-five seconds were
required to change from engine steering to steering by hand. By manual
gear the helm was moved from midships to hard a-starboard in 40 sec.,
from starboard to hard a-port in 2 min. 10 sec., and from hard a-port
to midships in 2 min. 20 sec. The heavy balanced rudder and the speed
of the ship throwing great labor upon the crew manning the wheels, the
hand gear was afterward disconnected and the connection with the
steering engine completed in 40 sec.
