Hansard HC Deb 18 July 1887 vol 317 c1208 and 1287 House of Commons, 18 July 1887 Lord Randolph Churchill said: "The Leander, built in 1885–6, was completed for £191,000; but in the same year the Admiralty spent £8,947 on her." Admiral Edward Field replied: "the noble Lord spoke of the Leander, of the great scandal of her costing within a short time of her construction over £8,000. Yes; but he did not tell the reason. Accidents will happen to ships as to other things; and an accident happened to that ship when she was with the Squadron on the Coast of Ireland. She ran upon a rock coming into Berehaven by the west entrance, and knocked a hole in her bottom. You do not suppose you could repair her for a mere nothing, and that sum represents the cost of the repairs of the ship after that accident."
Hansard: HC Deb 02 May 1902 vol 107 c558 "Mr. William Allan (Gateshead): I beg to ask the Secretary to the Admiralty if, seeing that H.M.S. Leander is to receive new boilers, he will state what type of boiler is being adopted, who were the manufacturers, what type of boiler is on her at present, and in what year were they fitted on board." Mr. Arnold-Forster: The old boilers of the Leander are to be replaced by single-ended cylindrical boilers. The boilers now being inserted are made by Messrs. J. Brown & Co. of Clydebank. The boilers which are being removed are also cylindrical single-ended boilers. They were fitted on board in 1883. Mr. William Allan: May I ask the hon. Gentleman why water tube boilers were not fitted in this ship, seeing that they are so much approved of? Mr. Arnold-Forster: Because the ship was built for cylindrical boilers, and no special purpose would be served by the installation of water-tube boilers in her case."
