'six, and a hemp core which provides place for fastening the ends. a plain, '24 Pt is simple process, and but the work of an hour for anyone to learn. -' In cases where an endless rope can- "not be put on already spliced, the rope has to be put around the sheaves, hove taut by pulley blocks, and the splice made on the spot. in diagram of splices. See Fig. 1 The necessary tools are a hammer ~ and sharp cold chisel for cutting off ends of strands; a steel point or mar- din spike for opening strands; two slings of tarred rope with sticks (see big. 5) for untwisting rope; a pocket -knife for cutting the hemp core; a _ wooden mallet and block. 'First--Put rope around the sheaves and heave it tight with good block The. blocks. and fall (see Fig. 1). _ should be hitched. far:enough apart so -20-ft. splice. as to give room between to make a A small clamp may be "used to prevent the lashing from slip- "ping on the rope where the blocks Hare hitched.(see Fig. 1). Next see that the ropes overlap about 20 ft., _ about 10 ft. each way from the cen- ter, as shown by the double arrow in Fig. 1. Next mark the double center on both ropes with a piece of chalk, .on the ground or floor, 6. the case may be. follow other end, lay it tightly in the open or by tying on a small string. Now proceed to put in the splice, with the blocks remaining taut, when neces- - sary; but the better way is to remove the blocks, throw off the ropes from . the sheaves, let it hang loose on the shafts, and proceed with the splice or scaffold, Second--Unlay the. strands of both ends of the rope for a distance of 10 ft. each, or to the center mark, as shown in Fig. 2. Next cut off the ' ° hemp cores close up, as shown in. Fig. 2, and bring the bunches of strands together, so that the opposite strands will interlock regularly with each other (see Fig. 3). Third--Unlay any strand, A, and ip. with strand.-1 -of .the groove made by unwinding. A, make twist of the strand agree exactly with the twist of the open groove. Pro- ceed with this until all but 12 in. of 1 are laid in, or till A has become 10 ft. long. Next cut off A, leaving an end about 12 in. long. Fourth--Unlay a strand, 4, of the opposite end, and follow with strand - D, laying it into the open grooveias "before, and treating this precisely as in the first case (see Fig. 3). Next * Pursue the same course with B and 2,: . stopping 4 ft. short of the first set. TAE Marine REVIEW Next with 5 and E, stopping as be- fore. Then with C aid 3; and lastly with 6 and F. The strands are now laid in with the ends 4 ft. apart, as shown in Fig. 4. Fifth and last--The bade. must now be secured without enlarging the diam- eter of the rope. Take two rope slings or twisters (see Fig. 5) and fasten to the rope as shown in Fig. 6; twist them in opposite directions, thus opening the lay of the rope (see Fig. 6). Next, with the knife cut out the hemp core about 12 in. on each side. Now straighten the ends, and slip them into the place occupied: by the core, then twist the sling back,' clos- ing up the rope, taking out any slight ineqtiality with a wooden : mallet. Next shift the slings and repeat the operation at the other five places, and the splice is made. Another easy way, consistent with strength, is as follows: Open up the strands as for, a long splice, and lay them up in the same way. Instead, however, knotting the strands together | with an overhand knot, separate each opposite strand into two parts and cross each part, tucking the ends under and over the laid up strands until the ends are expended. Worm, parcel, and serve over, and the splice will last. as long as the rope itself. - SAILOR'S LOG BOOK LAKE MICHIGAN, MANITOWOC.--The north pier at Mani- towoc is being removed preparatory to being replaced by new work. The north pier light has been moved 50 ft. westward to the center of the next -adjoining crib and will then be 75 ft. from the outer end of the pier. The outer crib will then be removed, leaving the light 25 ft. from the outer end of the pier; it will then again be moved 50 ft. westward. With these successive moves of 50 ft. each, the light will not be more than 75 ft. nor less than 25 ft. from the outer end of the pier, at any time. The removal will continue until the work is abandoned for this season, at which time the light will remain 25 ft. from the outer end of the pier. CHICAGO RIVER STILL OBSTRUCTED AT WASHINGTON STREET TUNNEL.--The Uni- ted States Lake Survey receives word from,Lieut. Col. Wm. H. Bixby, United States engineer at Chicago, that while the lowering of the Wash- ington street tunnel has been com- pleted and the old draws and ap- proaches thereto have been dredged, there are still four clusters of piles, marking the ends of the old protec- tion pier, which remain to be removed by the city of Chicago, and the boat channels have not been dredged to their full depth. At the present time, it is not safe for vessels to load to more than 18 ft. draught when using the south branch of the river south of Washington street. GREEN BAY, HILL'S, PT., STURGEON BAy.--A _ white, triangular, slatted target, apex up, has been established on Hill's Pt., southern side of: Sturgeon bay, to mark the point abreast of which ves- sels bound up the bay through the bridge to the canal should leave the Dunlap Reef range line and head for the bridge light. The target is located on the following bearings: Bridge light SE x S true, SE 7% S correct magnetic. Dunlap Reef range front light, SE x S % S true, and SE x S &% S cor- rect magnetic. LAKE SUPERIOR. WRECK OF THE STEAMER NIMICK.--The wreck of the steamer : Alexander Nimick lies sunk in 26 ft. of water 1% miles WNW true, and NW x W 34 W correct magnetic, from Vermil- lion Point life saving station. The wreck lies about 34 mile from shore and 11 miles westward of Whitefish Pt. It is entirely submerged, having about 2 ft. of water over the boilers and engines. Masters of small ves- sels should be cautious in keeping this shore too close aboard such as with the wind off land. The keeper of the Vermillion life saving staton has placed-a buoy just outside of the wreck. WRECK OF THE STEAMER NIMICK ABAN- DONED.--It is reported to the United States lake survey office at Detroit that the wrecked steamer Alex. Nimick, which was destroyed by the storm of Sept. 21 on Lake Superior at a point about 11 miles west of Whitefish Point and 1% miles WNW of Vermillion Point life saving sta- tion, has been abandoned by her owners, the Gilchrist Transportation Co. As the wreck is submerged and forms a menace to vessels hugging the shore, steps will be taken by Major Graham D. Fitch, United States engineer at Duluth, to secure its te- moval » -' NEW SHOAL IN STRAITS OF MACKINAC.-- The steamer, Search of the United States Lake Survey, which has been engaged in sweeping in the Straits of
