402 prominent characteristics of successful port administration. "There is necessity for providing large and convenient storage areas where cargo may be collected and cared for. "The lowest cost of handling cargo from the hold of the ship to the con- signee and vice versa was found to be in a port where one authority con- trols the "entire operation and where the transit sheds were three to five stories high.

New York, Baltimore and Port- land, Ore, have begun in the right direction. It is to be hoped that scores of other American ports will soon ap- preciate of the task before them, a.task which must be the magnitude performed if they are to hold their share of the sea-going and coastwise sommerce of this nation. for Penarth Roads dock afloat, and secondly the complete dock assembled. The dock, it will be seen, is of the off-shore or single-walled type, and was designed by Messrs. Clark & Standfield, London. It has an over- all length of about 380 ft., an extreme width "of 75. if, and is. capable. of accommodating vessels having a beam of 55 ft. with a draught of water up to 18 October, 1909 ft. and a displacement of 4,200 -tons. As the term off-shore implies, the dock is attached to the shore by means of booms which are hinged and _ pivoted at the dock, and also at the shore ends to permit of the lowering and raising of the dock when vessels are being docked or undocked. Two very power- ful sets of pumping machinery are sup- plied to the dock, consisting of four centrifugal pumps and engines manu- factured by Messrs. Gwynnes, Ltd., of London. Steam is supplied by two large Babcock & Wilcock boilers work- ing at 160 Ib.,. pressure. The plant is capable of lifting a vessel of 7,000 tons d. w. in the remarkably 'short time of three-quarters. of an hour. For. the purpose of self docking, the dock is divided transversely into two equal halves each with its own pumping plant, so that any one section can be docked by the remaining portion, one half being lif- ted so to speak in the lap of the other. A powerful steam capstan is fitted - at each end of the top wall to assist in working vessels into position when lift- ing or otherwise. Light, mechanical side shores are supplied, in addition to the usual accessories for facilitating the THE PENARTH Dock BerorE LAUNCHING.
