A New Propeller.

A most interesting trial of invention. which. in the opinion of the naval ana technical authorities who witnessed lt,
 promises tO effect an important change in the propulsion of vessels of all class es. was conducted on the Elbe, near Dresden. The inventor, Dr. Emil Fleis- cher. has applied the principles of hy- lraulic reaction in the propulsion of ships in manner which, according 10 | the testimony of officers of the German Imperial Navy. like Admirals NOn Henck and Werner. is as simple as Il is effective. It does completely away with all risks from accidents tO rudder or machinery. for there need be no rudder. and there is scarcely any ma chinerv; solves the problem of avoiding loss of power through transmission, | and. finally. reduces the perils of the sea to a minimum so far as injuries to the machinery is concerned. For. as ! Admiral Werner explained, the same
 immense force that propels the vessel can, at a moments notice. be used tO pump her SD eflectually that she would
 remain afloat with a considerable leak in her bottom; while in case of fire
  | ing it. Besides tine two admirals above mentioned there were present at the trial NJ. DauzatS, of Paris, as represen- tative of M. de Lesseps; MessrS. HO- wald. of kiel. who are among the larg- est steamship and engine builders in Germany. and who have built a sea- ! going vessel on the same principle for | Dr. Fleischer Gin which. accompanied
 bv Admiral Werner, h. made a sue cessful trip in very rough weather to | Copenhagen and back tO kieD; NIT. Sulzbach. the eminent banker of Frank | fort-On-the-M Main. and several other | gentlemen interested in the invention.
 The vessel, named the HydromOtor.
 is sixty metres long by seven metres broad, draws 06O metres. and Is throughout constructed of iron. The navigation of the Elbe, near Dresden,
 presents many obstacles in the shallows and rapids which occur at frequent in tervalS. NoiseleSS and without any os- cillatiOn did the large vessel-large as compared with the stcamcraft plying on that part of the river after the simple turning of lever by the captain on the bridge, commence its trial trip, stem ming the current and keeping an even course under the picturesque right bank of the river. The only noise audible
 was that of the rushing of the water from the tubes, fixed little above the
 river, and nearly amidships on both | sides of the vessel. Another turn of the lever and the action was reversed. ! The vessel comes tO a dead stop in less | than her own length. By tEc alternate use of the levers she may be turned | round on an almost stationary pivot. | The captain handles tue levers on his ! bridge independent of all communica- | ton with the engine room. The gentle ' men present watched the trial with the | utmost interest. Arrangements are
 now being made to apply the invention | on very large scale. The opinion of
 Admiral Von Heuck regarding the Fly
 dromOtor i> as follows:
 1.-The principle being correct, the in | vention has almost certainly a future
 before it, if it be subjected to certain | alterations. Beyond doubt the hydro
 motor is emincntly useful for river
 ships. especially in shallow rivers, be- | cause it draws very little water. and in
 canals because i; raises no waves, and consequently does not injure the banks.
 It iS also of decided importance as an
 auxiliary steam engine in sailing ships, | when there k no Wind-as often hap
 pens. for instance, in the Mediterranean
 and in the tropics. Another advantage | it has for sailing ships is that 1t does not require extra hands. lt will unde-
 niably be of value in war ships also,
 for. as auxiliary tO the screw, it will
 considerably increase their power of turning. and, therefore. their power of
 attack and defense. How far the hv-
 dromotor will bc able to modify or
 even super>ede the present ship engines
 il Is aS vet impossible to Sly. Certain
 iy it will do SD Co considerable ex- |
