To Correspondents.
G. Blake.—-In answer to your question, Mr Smart, superintending engineer of the Union Steam Ship Company, kindly supplies the following explanation:—"For going astern, a turbine is fitted at the after end of each low pressure ahead turbine, and is attached to the same shaft, these being- the side shafts. Tha astern turbines are exactly similar in construction to the others, only they are smaller in diameter, and the blades are set at the opposite angle to the ahead ones, and as steam is admitted to the asetrn turbines at the after end of the turbine casing, the direction of the shaft rotation is reversed. In ntancßuvrin*. the centre of high pressure turbine is closed, the two side ones only being used. These can be manipulated by suitable valve and pipe connections to go ahead or astern together, or one to go ahead and tli3 other astern."
