Introductory text reads: While one reflects on those many and frequent Accidents, which thro' want of Swimming daily happen amongst us: Every one is ready to complain of the unhappiness of Man in that respect, in comparison of other Animals, to whom Nature has indulg'd that faculty, which he ought to enjoy in a more excellent degree, since it is so necessary to his Preservation.... To mention a few advantages of Swimming. In case of Shipwrack, if one is not very far from Shore, the Art of Swimming may set one safe there, and to save from being drowned. In case of being pursu'd by an Enemy, and meeting a River in ones way, you have the advantage of escaping two sorts of Death, by gaining the Shore on the other side, and so escaping from your Enemy, and from being drowned in the attempt of doing it.
