68 529,162 has been paid in dividends and $3,035,380.77 has been carried forward to depreciation and _ profit and loss account. This means that the company has paid out in dividends only one third of its available cash. Not a man connected with the MARINE REVIEW Merchants and Miners, or anyone else familiar with conditions surround- ing the company after the railroad administration turned the property back to the owners, but feels that the wonderful change, from a disrupted organization with wharf properties January, 1927 and ships in indifferent repair and with the good will of shippers and travelers dissipated, to its present sound and prosperous condition, is due to the wise and courageous man- agment of A. D. Stebbins president and general manager. Radio Compass Is an Aid to Safety HE radio compass is a definite | aid to navigation on the Great Lakes as well as the ocean. The results for accuracy and dependability obtained by the navigators on Great Lakes ships such as the Quincy A. Suaw of the M. A. Hanna Co. ex- ceeded expectations. Captain Colson of the Quincy A. SHAW may be con- sidered a pioneer in the correct use of the radio compass on the Great Lakes. Some of his bearings taken at distances ranging from 5 miles to 215 miles show practically no varia- tion from calculated bearings. The maximum error shown is one degree. In the early days of the radio com- pass many obstacles presented them- selves in obtaining correct bearings. For instance, it was found that all nearby objects such as stacks, railings, rigging and the hull of the ship itself, affected and changed the indicated direction of oncoming radio waves true. causing serious errors. No two ships were alike. The causes wer found to be fundamental and as hard and fast as the law of gravity. To overcome this Dr. Kolster evolved his automa- tic mechanical compensator. By means of this device, the vessel’s radio com- pass is calibrated and all natural er- rors are eliminated so that when the loop is rotated and a bearing taken, the direction under the sight wires on the compass card reads _ absolutely The automatic compensator, to correct nature’s ills, thus becomes the most important part of a radio com- pass. Without it false bearings would result, the degree of error depending upon the construction of the ship. The operation of the Kolster radio compass standard model made by the Federal Telegraph Co., San Francisco, is very simple. It was never intended by the inventor Dr. Kolster that a radio operator should have anything to do with the operation of the radio compass and the apparatus requires no tuning. It is only necessary to set one dial to the wavelength desired, and all fixed radio beacons operate on 1000 meters. Mobile beacons, another development of Dr. Kolster will soon be an established fact and they will probably. operate on approximately 850 meters.. These will be installed on board ship and are strictly for colli- sion prevention, used in conjunction with a radio compass. They are of low power, with an estimated service range of 10 miles. To obtain a radio compass bearing with the Kolster device, the navigator merely pulls a snap switch which turns the current on the receiver. He then rotates the loop by means of a convenient hand wheel and listens in / RADIO COMPASS ON THE GREAT LAKES STEAMER QUINCY A. SHAW OF THE M. A. HANNA CO. the head phones for the minimum signal. To find this exactly he rocks back and forth across the minimum. The signal is heard on each side of the exact minimum. The minimum, or silent point, is his true bearing and it will be accurate within two degrees or less which is one-half of one per- cent or less. He reads the bearing on his compass card which may be dumb, magnetic, or sperry repeater. The bearings on the radio compass are sharp as well as true. The Great Lakes district is now favored with seven radio beacons maintained by the United States bu- reau of lighthouses. Four more are under construction and two additional are projected. Although radio compasses may be used in any part of the world where radio is used, the radio beacon is a ‘valuable conjunctive aid for ships equipped with the radio compass, be- cause it is designed especially for that purpose and no other. Radio beacons emit characteristic radio signals which are clear enough to be easily recog- nized by any navigator. A ppointed Chief Engineer Newark Terminal H. R. Hanlin, president of the Mercur Trading Corp., New York, has announced the appointment of Herman W. Ordeman, as chief engi- neer with headquarters at the Newark Seaboard Terminal, Port Newark, N. J. Mr. Ordeman is well qualified through his previous engineering work in the railway and terminal field to plan and supervise the im- provements planned by the Mercur Trading Corp. for the terminal which it has recently leased from the United States government at Port Newark. A graduate of Washington and Lee university, Mr. Ordeman has_ been construction engineer with the Atch- ison, Topeka and Santa Fe railway, division engineer of the Baltimore & Ohio railway, chief engineer of the United Terminals Inc. and has been engaged in consulting work in New York and _ ~vicinity on waterfront structures and terminals. Mr. Ordeman is one of a number of specialists now engaged on a sur- vey of the Newark Seaboard Terminal with the object of perfecting its future development as a_ railway, marine and storage terminal which will render maximum service to mer- chants and shippers here and abroad. The speed of construction of the Augustus has set a record. for Italian shipyards. The vessel was launched less then eight months from the day the keel was laid and is expected to be ready for her maiden voyage within seven or eight months.
