The success of the magnet in this instance has been responsible for its utilization in other fields of submarine endeavour. A freighter was sunk with a valuable steel cargo aboard. The vessel was examined and found to have settled upon an even keel. Divers descended and opened the hatchways, while sections of the decks were cut away to expose the cargo. The magnet was then brought into action, and the cargo unloaded as readily as if moored alongside the dock. This success in the open sea has been responsible for the salvage of similar cargoes which have been lost around our coasts. So far as the Pickett-West lifting-magnet is concerned, there is no obstacle to its use in this field so long as sufficient swing can be imparted to the suspended apparatus to ensure sweeping of the wreck, and up to the depth corresponding to the pressure of the insulation in the coil drum. Seeing that this is introduced at a pressure of 120 pounds to the square inch, the lifting-magnet can be safely used in water up to a depth of approximately 250 feet without the insulation collapsing under the imposed water-pressure, and this is a depth far beyond that at which a diver can work. But, taking the wrecks lying within water accessible to the diver, appreciable recovery should be possible. It is generally conceded, in view of the success which has already been achieved, that there is a promising future for the apparatus in this field so long as it is designed and constructed along correct lines. The cost of operations will be reduced therewith very materially, and the strain imposed upon human effort as represented by the diver will be decreased very markedly. Instead of salvage operations being confined to an hour or two daily, according to the velocity of the tides and currents, it will be possible to continue work during the round twenty-four hours so long as the weather is propitious. The operator will be able to sweep the wreck from end to end, as well as to scavenge the sea-bed by swinging his magnet, confident in the knowledge that magnetic metal will be trapped in the process for haulage to the surface. Even if ships should prove impossible of recovery intact there is nothing to prevent their reclamation piecemeal. Dynamite will reduce the wreck to scrap of weight and size within the lifting capacity of the apparatus, and at the price obtaining for such junk the expedient should prove profitable. So we should be able to retrieve a certain and imposing proportion of the wanton waste incurred by the ruthless attacks of the enemy upon our sea-going traffic.
