Successful Trials,
The official trials of the vessel were exceptionally successful no mishaps of any kind occurring in the propulsion equipment.
It is a point of great interest to note that the temperature rises of all machines were so low that it was posisble to run the venael at two knots faster speed than had been allowed for in design:

Luxury Ship.
The Monarch of Bermuda is a quadruple screw turbo-electric- luxury liner built by Vickers- Armstrong, Ltd., to the order of Furness, Withy and Co., Ltd., for the earriage of passengers, maila and general and refrigorated car- goes between New York and the island of Bermuda. This service is probably the most luxurious in the world, the wealthy patrons de- manding an extremely
