��THE three and six-pounders with which all the sea-going cutters of the scr\'ice are armed now are used to shoot lines to vessels in distress. For years they had served as nothing more than ornaments on the decks of the cutters; for it never was necessary to use them in the enforcement of customs and navigation laws. They were carried mainly for their moral effect.

These guns have been found far more effective in line shooting than the line guns formerly carried — small brass cannons of the type seen a t life-saving stations along the coasts. Although the cannons were in use for many years, they were never en- tirely satisfac- tory. It was almost impos- sible to aim
