[Illustration: THE NEW BRITISH CRUISER BLAKE.]
Before dealing with the engines and their trials, it may be stated
that the vessel is of 9000 tons displacement at 25 ft. 9 in. mean
draught. Her length is 375 ft. and her beam 65 ft. She was built at
Chatham, and the armament consists of two 92 in. 22-ton breech-loading
guns, ten 6-in. 5-ton guns and sixteen 3-pounder quick-firing, and
eight machine guns, with torpedo launching carriages and tubes. The
propelling engines were manufactured by Messrs. Maudslay Sons & Field,
Lambeth. They were designed to develop 13,000 horses with natural, and
20,000 with forced draught. They consist of four distinct sets of
triple expansion inverted cylinder engines, and occupy with boilers,
etc., nearly two-thirds of the length of the ship. They are placed in
four separate compartments, two sets being coupled together on the
starboard and port sides respectively for driving each screw. There
are four high pressure cylinders, 36 in. in diameter; four
intermediate cylinders, 52 in.
