the keel and the oil was carried in tanks beneath the floors of
the cars.

The wireless cabin was situated as before mentioned in a cabin in
the keel of the ship, and the plant comprised a main transmitter,
an auxiliary transmitter and receiver and the necessary aerial
for radiating and receiving.

No. 9 was inflated in the closing days of 1916, and the disposal
lift was found to be 2.1 tons under the specification conditions,
namely, barometer 29.5 inches and temperature 55 degrees
Fahrenheit. The contract requirements had been dropped to 3.1
tons, which showed that the ship was short by one ton of the lift
demanded. The flight trials were, however, carried out, which
showed that the ship had a speed of about 42 1/2 miles per hour.

The alterations previously mentioned were afterwards made, the
bags of the ship were changed and another lift and trim trial was
held in March, 1917, when it was found that these had had the
satisfactory result of increasing the disposable lift to 3.8 tons
or .7 ton above the contract requirements, and with the bags 100
per cent full gave a total disposable lift of 5.1 tons.

Additional trials were then carried out, which showed that the
speed of the ship had not been impaired.

For reference purposes the performances of the ship are tabulated
below.
