OCTOBER 3, I9OI. THE MARINE RECORD. 13 SUN’S AMPLITUDES. The following approximate amplitudes of the Sun’s ris- ing or setting will be given each week in this column dur- ing the season of navigation. A second bearing, may be taken by compass at sunset, by reversing the east bearing given for the nearest latitude, as the change in declination for a few hours makes but a slight difference in the true bearing of the sun’s setting. The bearing may be taken when the sun’s center is on the horizon, rising or setting. The elements which may be obtained by taking these am- plitudes are the quantities known as local attraction, va- riation and deviation, or the total difference between com- pass and true, or geographical bearings.

MELO — Oe 7s Be ES With a compass correct magnetic, the difference between the observed and true bearing or amplitude will be the variation for the locality. Should there be any deviation on the course the vessel is heading at the time of taking the bearing, the difference between the observed and the true amplitude after the variation is applied will be the amount of deviation on that course. If the correct magnetic bearing is to the right of the compass bearing, the devia- tion is easterly, if to the left, the deviation is westerly. OO OS Wo. R. TRIGG Co., Richmond, Va., have just been award- ed the contract for a steel tug-boat for the Pennsylvania Railroad Co., to be usedin New York harbor. The order for dredging the Southwest Pass of the Mississippi river, for which Capt. J. C. Sanford, U. S. Engineers, at Charleston, opened bids Aug. 13, has been awarded to the Wm. R. Trigg Co. The pumping machinery for this dredge will be fur- nished by the Bucyrus Co., of South Milwaukee, Wis., and will consist of two 20-inch single suction centrifugal dredg- ing pumps with direct compound condensing engines and the necessary dredging outfit. This dredge will be the largest and most complete sea-going dredge which has yet been built for the U.S. Government. It is the first sea-go- ing hopper dredge which the Government has purchased with a steel hull and twin screws. The dimensions will be, over all, 271% feet; molded beam, 4734 feet; molded depth, 23 feet. She will have a hopper capacity of about 2,000 cu- bic yards. The propelling engines will be compound con- densing with cylinders 20 and 4o by 30 inch stroke. In other respects the dredge will be a complete sea-going ship with extensive cabin accommodations for officers and crew, with complete electric light outfit. She will steam at the rate of not less than ten knots per hour. REPORTED BY THE LOOKOUT. North and South Tonawanda received six to seven million feet of lumber on Tuesday. Local firms are stocking up a winter supply. Lumber canal ripen are $1.60 to Albany and $2 to New York. The Celtic can carry between 2,700 and 3,000 passengers: without crowding. Of these, 350 arein the saloon, 150 in the second cabin and 2,300 in the steerage. Her crew num- bers 350, nearly half of whom belong to the steward’s de- partment and look after the wants of the passengers. A gentleman who is deeply interested in the enactment of a subsidy law has been searching the published utterances of President Roosevelt with a view to discovering his exact position. The search has been virtually fruitless, however, for the reason that, beyond general statements advocating the spread of American commerce, the new President has not, apparently, placed himself on record. There has lately been a great deal of speculation as to the conditions affecting the flow of water to and from the Great Lakes, but it appears to be mostly guess work. ‘The fact is the Great Lakes get their supply from an enormous water- shed, and the quantity which runs into them and out of them varies as the season is dry or wet. But from present ap- pearances there is enough on hand to keep the falls going indefinitely. Gradually the barges are forcing the fore-and-aft rigged craft from the coastwise coal, lumber and ice trades on the Atlantic. Recently they have entered the West India bus- iness. So much of the coastwise trade has been taken by the barges that owners of schooners, have begun sending their vessels across the Atlantic, carrying lumber and oil. Thisis considered expensive, as the schooners are not always sure of areturn cargo. Barges now lead the schooners in carry- ing coal from Philadelphia. Northern Michigan and Wisconsin lumbermen are mani- festing a constantly increasing interest in the timber lands of the Pacific coast. From Marinette and its sister city across the river there has been a great exodus of mill men and investors tothe far western country for many months past and the movement is gradually spreading to other sec- tions of the upper peninsula. Several hundred have emi- grated from the Menominee river during the past few years, and a party of mill men expect to leave next week. Michael McLaughlin has brought suit against the San- dusky and Island Steamboat Co. to recover $1,000, in which amount he claims to have been damaged by having been thrown off the steamer Arrow at Cleveland. Plaintiff claims that he bought a ticket at Cleveland to Sandusky, via the steamer Atrow; that the employes of the boat refused to accept it, and wrongfully, forcibly, maliciously and unlaw- fully did force, expel and drag him from the boat in the presence of many of. his personal friends. This action caused him much mental distress, he contends, and he asks damages in the foregoing amount. At a meeting of the Commerce Committee of the Maritime Association of the Port of New York, held on Monday, which includes in its membership the members of the exec- utive committee of the association, it was decided to discon- tinue the association’s membership in the Canal Association of Greater New York and in the New York Commerce Con- vention. President Kunhardt was directed to inform the officers of the associations referred to. This action leaves the Maritime Association of the Port of New York free to pursue an entirely independent course with reference to af- fairs concerning New York’s commerce and canals, NOTICE TO MARINERS.
