A Lecture, Or Essay On the most efficacious means of Preserving The Lives Of Shipwrecked Sailors And The Shipwreck

 endeavour to illustrate their application and use, as in actual casesof difficulty and danger. Having now closed my address, I shall proceed to the immediate object of the Lecture, and shall divide my subject under the two following heads :— First, the construction of apparatus for effecting communication with vessels stranded on a lee-shore, with directions for their uses in preserving the lives of the people on board during the ught of day, and also the extreme darkness of night. Secondly, the apparatus requisite, and method of its application, for affording assistance in the most violent storms to vessels in distress at a distance from land, as well for the preservation of life and pro- perty, as the PREVENTION of SHIPWRECK. A vessel stranded is one driven on shore, like the one here shown • which will serve also to show the difficulty of giving assistance in a violent storm by manual exertion to throw a rope by hand against a furious wind; it will point out at the same time the impracticability of forcing a boat by the power of oars over a high raging sea, and the impossibility of applying the mode of relief from the ship to the shore It may be proper, before I proceed further, to state, a rope projected over a vessel, and falling on the rigging, is termed ‘communication-’ and I shall now endeavour, by a progressive explanation of my plan and the illustration by models, to point out the means that have been successfully employed to effect this important object. The pieces of ordnance required for this service should be as light in their construction as the purposes for which they are intended will
