282 and stationary portion may be en- countered without any damage to the blades other than burring of the ends. In order to permit the gear pinion to float longitudinally without impos- ing any end thrust on the teeth of the pinion or gear, a special flexible coupling was designed by Mr. West- inghouse, which is illustrated in Fig. 15. As will be seen, the coupling consists simply of two flanged collars, one on the turbine and one on the pinion drive shaft, and a ring Rk bolted to the portion of the coupling on the turbine shaft. There is a slight clear- ance between the ring R and the hub S, and the driving force is transmitted through the ring R to the hub S by means of steel balls B, which are in- serted in holes drilled partly in the ring R and partly in the hub S. These holes are lined with hardened steel FIG. 14 bushings made in halves, and the balls are retained from coming out of the hole by means of the retaining ring T.: As will be seen, this coupling is extremely simple and facilitates tak- ing the turbine spindle or pinion out without disturbing any other part. After extended service, it has proven itself entirely satisfactory for this work. Steel Tug Maycliff The new steel tug Maycliff, -de- signed by Cox & Stevens, for the Undercliff Terminal & Warehouse Co., of New York and Edgewater, N. J., made a successful trial trip up the Fast river recently. The vessel THE MARINE REVIEW was- contracted for originally with John H. Dialogue, of Camden, N. J., but completed by the Staten Island Shipbuilding Co. at Port Richmond, N.Y. She is 110 ft. long, 27% ft. beam and draws 1314 ft. of water. Her engine is of the fore and: aft compound type, with cylinders 19 and 42 in. in diameter with 30 in. stroke ,of piston, and indicates over 800 H. P. There. is a spacious salon in the after part of her steel deckhouse capable of ac- commodating about 50 guests. Her equipment includes a steam steerer, a Kahnweiler steel lifeboat, a Shipmate range furnished by the Stamford Foundry Co., Stamford, Conn., and a Ritchie patent compass from E. S. Ritchie & Sons, of Brookline, Mass. She is lighted by electricity furnished by a General Electric Co. dynamo. Panama Canal Pilots The following arrangement has been approved in connection with the handling of applications for the po- sition of canal pilots: The Washington office of the Pan- ama canal will handle all applications for the position of canal pilot from the region of the Great Lakes, obtain as much necessary information in regard to their qualifications as prac- ticable, arrange an eligible list in the order of merit and submit it, through the governor, to the superintendent of transportation on the Isthmus, accompanied by the full file of the applicant, to be returned later. The Washington office will then make the appointments, when notified by the governor to do so. aS All other applications will be han- dled direct on the Isthmus by the su- perintendent of transportation. There are already on file a great many ap- plications from employes on the Isth- mus, from officers of the Panama Railroad Steamship Line, and from officers of other vessels running to Isthmian ports, most of whom the superintendent has examined in per- son. The result is that ample mate- rial has been found for the comple- ment of pilots that will be necessary for the opening of the canal. In view of the large number of applications already received, and of the fact that they are still coming in, it is believed that there will be no difficulty in in- creasing the complement of pilots as the trade of the canal warrants. No applicant is considered eligible for examination unless he holds a master's license for the Great Lakes or ocean going vessels of unlimited ton- nage; he must be under 45 years of age, and an American citizen. Canal pilots will be required to July, 1914 wear uniforms when on duty. 'The material selected is cream colored Palm Beach cloth, plain, without stripes or figures. The caps are to be stiff, after the pattern of those worn by the petty officers of the U. S. Navy, and will be of the same color as the uniforms. They will have a device in front consisting of a partly closed wreath containing the word. (Piot".

Detroit's Water Supply President Livingstone, of the Lake Carriers' Association, has sent out the following circular to the boats, which is self-explanatory: "The Detroit water board has pre- sented the subject of the pollution of the drinking water of the city of Detroit to the consideration of the Lake Carriers' Association and after several conferences has made a fe- quest which is believed to be eminent- ly within its rights, and that is, that no refuse shall be thrown overboard from vessels and that all toilets shall be closed within a reasonable distance of the intake of the city's water sup- ply. "The area which is bounded by a line drawn east and west 4 miles north of the present location of the Grosse Point lightship and a line drawn east and west from opposite the head of Belle Isle, is regarded as reasonable; or to define the area in another way--from the head of Belle Isle to .Lake St. Clair gas aad bell buoy 20-A, which marks the for- mer location of the Grosse Point lightship.. While the vessels of the association are within this area it is expected that all toilets will be closed and no refuse thrown overboard. "Tt is understood that the passenger lines have given the Detroit water board assurance that they will respect the area defined above and, therefore, it is expected that no vessel enrolled in the association will pollute it. "Masters should be instructed to observe this request." Naval Constructor H. A. Evans, who recently resigned from the navy, has been elected vice president and general manager of the Skinner Ship- building &.Dry Dock Co.
