Before they could get her home, however, her rescuers were compelled to beach her and struggle to save one or two very urgent cases. They accordingly put her ashore in a sheltered bay in the Isle of Wight where they knew she would be quite safe until such time as they could attend to her. She was months making a short trip of a few miles round the south coast, but she seemed to have as many lives as a cat, and eventually reached dry dock where the damage wrought by German torpedoes was properly repaired. The remarks of the Germans must have been rather interesting when they discovered that they were torpedoing the same ship time after time. Probably they thought it was some trick the British were playing on them, some gigantic bluff to make them waste torpedoes. Anyway, although they tried and tried and tried again, the Admiralty salvage men, not to be outdone, managed to save the ship from the clutches of the Germans after all. So long as the submarine campaign continued, it was indeed a gigantic tussle between pumps and patches and torpedoes. At first the torpedoes had it all their own way, but pumps and patches in the skilful hands of the Admiralty Salvage Section began to rob the Germans of more and more of their prizes, and they ultimately proved a most important factor in bringing home to the foe that the game was not worth the candle. The demand for pumps of all types was tremendous. Motor pumps, steam pumps, electric pumps--all were required, and the pump-makers were kept busily employed night and day. The war brought out the good points of one pump known as the electric submersible pump. Invented in pre-war days by an electrical engineer named Macdonald, this invention did not attract the notice it deserved, and in the end the inventor sold out his rights and emigrated to Canada. Since then his pump must have been very successful financially, for one or two that happened to be aboard a battleship at the battle of Jutland did such wonderful service that the whole of the British Navy was fitted with them.
