A new ship's rudder has just been invented by an Australian, and tested on a motor launch with very satisfactory re- | suits. The rudder is in two halves or j ings, r.nd these may be extended—when j ' aey form a complete circle—or closed, as required. When shut, the wings act as au | ordinary rudder: but when open, instead ' of the corkscrew action of the propeller forcing the vessel ahead, it throws the I water back on to the flat suihuio of the open rudder, and thus the power which, without obstruction, would move the body | through the water is converted into a, • brake. The rudder does not, however, : reach the limit of its extraordinary powers with the stoppage of the vessel, although if the wings are not moved from the . straight line the vessel may remain station- [ ary with the engines racing full speed ! ahead, but if the wings are brought still ; further back, and incline towards the sides, ' she begins to move astern with the propeller still working ahead. j Magistrate and Constable.—" Did you | arrest tho prisoner, M'Nutty?" "I did, ' yer Worship." " Did he offer any resist- j AiLcal" " Qalg a sluttingj yer Wcushii}." •
