If this be the case, the work on the jetties has al-ready accomplished much more for the South Pass thanmany years of laborious and expensive dredging have beenable to do for the Southwest Pass.—Philadelphia NEW LAMPWICK TRIMMERS. Mr. John Bannihr, of Hempstead, N. Y. has pat-ented (July 4, 1876) through the Scientific Ameri-can Patent Agency, a novel improvement in lampwick trimmers, which is represented in the accom-panying engraving. The shear cutters, A, are contrived to cut alikeand at the same time from both edges of the wickto the center, whereby the wick is trimmed betterand more uniformly than when cut across from oneedge to the other. The cutters, which are curved fortrimming the wick in form for an oval burner, areextended down at the ends a suitable distance belowthe point of cutting, and pivoted together at bothends, B, and also to a supporting ring, C, that restson the burner some distance below the top for asteadying support, and for a gage to govern thehight of the cutting above the top of the burnerThe levers for working the cutters are pivoted tothe standard, E, mounted on the ring, C, and are connectedto the cutte
