When the ship was tied up at CaliforniaCity there were no repairs to be made and she couldhave turned around for a long sea voyage the nextday if necessary. The turbine on land has come to stay and its ad-vantages are equally important, or more so, and quiteas available at sea. The principle of the turbine is not new and whathas held back its development the most has been the. Turbine and Generator. lack of a suitable application of its high speed untilthe advent of the dynamo. It has been asked whyship owners have not already taken advantage of theeconomy and reliability possessed by the turbine. Itis because a suitable means of speed reduction has not April 4, 1914.] JOURNAL OF ELECTRICITY, POWER AND GAS 293 been thought out until quite recently. The turbinebuilders have been too busy ashore to go to sea. Ahigh speed turbine can be hitched up to the low speedpropeller by means of motors or by gearing designedfor the purpose. Different conditions may make oneor the other desirable but the turbine is back of eitherof them. The results obtained in the trial are as follows: 48 Hr. Run—Maximum Attainable Speed. Trial Runs. Average sustained speed, knots per hr. 14,996 Shaft 7,152 Shaft Lb. steam per shaft Lb. coal per shaft 24 Hr. Run—10 Knots per Hr. TrialRuns. Lb. Steam per shaft Shaft 2,157 Shaft 7
