Richard A. Fletcher, Warships and their story (1911)
“ The duties of the modern cruiser are multifarious. She has to be no less a commerce protector than a commerce destroyer, and while at one end of the scale she may be little more than a glorified gunboat, she may at the other end have to be able to take her place in the line of battle and help her more powerful sisters. Whatever her duties, speed is regarded as of great importance.The Iris, in 1878, attained a speed of eighteen and a half knots, but more than seventeen years elapsed before this speed was equalled by any of the cruisers. ”
