Toprevent her from turning bottomside-upa control tank with a lifting capacity ofmany tons will be attached by an ad-justable purchase to the foremast. Thiswill act as a lever to pre\-ent the shij)from upsetting. Finalh-, air is forcedinto the space between the decks andthe upturned side, to bring the portside of the ship just le\el with thesurface. As soon as the Washingtonian isbrought to the surface she will be towedinside the Delaware Capes where shewill be grounded. It will then be a com-paratively easy matter to right POSITION OF WRECK LIFTING FROM THEBOTTOM rLOATINS AWASH The salvors predicted that the ship would occupy three different positions as she rose to thesurface. A control tank attached to the foremast prevents her from turning bottomside up compartments, interdeck spaces, andthe various tanks. The first step insalvaging the craft is the locating of thetwo distributing bases, one forward andone aft. To these bases flexible rubberhose, strongly protected by wire netting,was led to a surface float upon whichindi\idual connections were placed. Thefloat was pemianently anchored over thewreck. The compressed air from thepumps on the wrecking boat was sentthrough flexible hose connected with the The water will be pumped out, herwound repaired and she will be re-floated. The scarcity of ships and the highfreight rates ha\-e Viecn two factorsinspiring the sa\ing of the ship. At thetime the ^?essel was sunk she was valued,outside of her cargo, at a rough halfmillion dolla
