The hawser is thenset up taut by the people on shore, with tackles, sand-anchors, and crotches, and with the second orhauling line various appliances maybe hauled back and forth until all hands are saved. The methodof transporting persons from a wreck to the shore, used exclusively on the coasts of the United States,is by means of a covered metallic boat, known as the life-car, Fig. 2802, which is sufficiently large tocontain four grown persons or eight small children. It is made of light galvanized iron, and whenthe hatchway is closed is nearly water-tight. The time usually occupied in arranging the lines andsending off the car, after firing the mortar, is about 30 minutes ; and with the apparatus in proper LIGHTHOUSES, CONSTRUCTION OF. 293. order the car can make the passage from the wreck to the shore, traversing in each trip a distance of350 yards through a raging surf, within ten minutes. The life-car was introduced into the U. in 1849, and in the following year was instrumental in saving 201 lives from the Britishemigrant ship Ayrshire, cast away on Squan Beach, N. J., during a fearful snow-storm. This modeof conveyance of passengers from wrecked vessels was the invention of Capt. Ottinger of the U. Marine. Its advantage over every oth- oono er plan consists in landing women and childrenin perfect safety, and often without even get-ting wet. Fig. 2803 represents the life-car onthe rope. Life-Saving Rockets may be used to carrylines to wrecked vessels when guns and shot ofthe type described are not employed. Boxersrocket is represented in Figs. 2804 and consists of two rocket bodie
