68 Notable Rescue of Lake Superior HEN the officials of the Pittsburgh Steam- ship Co. met with the masters this year, among the first things considered and rewarded were the acts of heroism per- wae, «= formed im actu a! service during the Capt.W.J.Hunt year. In fact, lake owners are quite quick to reward meritorious service of this kind. These lakes frequently ex- perience very dirty weather and with the lee shore always present nasty sit- Tue DINKEy, DrirtinGc BROADSIDE uations are not uncommon. There are illustrated herewith two of the rescues made by Pittsburgh Steamship Co. mas- ters during the year. As stated in the January Marine Review, one was on Oct. 3 last, . when Capt. .W... J; Hunt rescued 13 members of the crew of the steamer Hopkins, who had abandoned the steamer and had taken to the yawl boat. There was a 25-mile southeast wind and a heavy sea, so that the yawl boat could do nothing but run before it. Fortunately they had a new metallic lifeboat, otherwise they could not have lived in the sea that was running. When Capt Hunt sighted the boat, he ran to windward of them and put his vessel into the trough. As the Dinkey was light, the wind had a tendency to bring her around again, but he kept kicking her on a starboard wheel and gradually drifted down broadside to the yawl. THE MARINE REVIEW The Dinkey then got a line to the yawl and threw out storm oil in pailfuls until the sea was killed, although, of course, the swell was still there. The Dinkey then moved ahead slowly on a starboard wheel, pouring oil out for- ward until everyone was aboard. The life boat was then hoisted aboard. The crew of the life boat consisted of 12 men, one woman and a dog. Temperature-Entropy Diagram Prof. Charles W. Berry's book on "The Temperature-Entropy Diagram," published by John Wiley & Sons, New York, has now gone into its third edition. The revision includes DowN TO THE YAWL, insertions in the chapters upon the flow of fluids, the gas engine cycles and the non-conducting steam engine. The chapter on refrigeration and the warming engine has been expanded into separate chapters upon each sub- ject. A special chapter has been added upon entropy analysis in the boiler room. The tables upon the efficiency, water and heat consump- tion of the Rankine cycle have been extended to cover the range of low- pressure turbines as well as_ high- pressure reciprocating engines. All illustrative problems have been re- calculated to agree with the most re- cent and accurate data upon steam. The second and third editions of. this book have so extended its scope that it is now a treatise upon graph- ical thermodynamics although - still abiding by the limitations imposed February, 1912 by its title. The price of the book is $2.50. Government Dredges Bids for building two steel dredges for the United States government, for use on Sacramento river, Cal., were opened in San Francisco, by Maj. Cheney, as follows: Ellicott Machine Works, $205,000 for one dredge or $336,000 for two; Yuba Construction Co., $231,700 for one dredge or $439,500 for two; Moore & Scott Iron Works, S. F., $241,500 for one dredge or $471,000 for two; Un- ion Iron Works, S. F., $267,750 for one dredge or $517,100 for two; Stand- KILLED THE SEA BY THROWING OVERBOARD STORM OIL ard American Dredging Co., $300,000 for one dredge or $500,000 for two. The United States senate has passed the bill to change the names of the lake steamers W. R. Wood- ford and Arthur H. Hawgood to N. F,. Leopold and Joseph Block re- spectively. These vessels were re- cently purchased by the Inland Steamship Co. It is reported that the Zenith Dredge Co., of Duluth, has secured the con- tract for the dredging operations in- cidental to the building of the new coal dock at West Duluth for the Is- land.
