The White Star Line has services from NewYork and Boston to Mediterranean ports vidAzores. The vessels engaged in the summer arethe Cretic(13,518 tons), Canopic(12,097tons),and Romanic (11,394 tons), to which in the winterare added the Cedric and Celtic. Of various freight and live-stock steamers thelargest are the Georgic (10,077 tons), Cevic *(8300 tons), and Bovic (6583 tons); the first-named, for example, will carry 10,000 tons of PLATE XLIII. ALLAN LINER VICTORIAN READY FOR LAUNCHING. THE ATLANTIC FERRY 287 Of several vessels built previously to 1892 with theidea of separating the passenger and cargo services,only the Naronic calls for special mention, for inthe fate of this vessel was exemplified the perils ofocean voyaging, against which the utmost humaningenuity and forethought are powerless. TheNaronic when only a year old, sailed fromLiverpool on February 11, 1893, and after she leftsight of Ireland was never again seen. A few weekslater a vessel picked up a couple of the Naronics empty boats in mid-Atlantic, and for the restnothing can be known until the sea gives up itsdead. Such a tragedy causes one to doubt the claimsof the much vaunted double-bottoms and watertightcompartments. In a case of collision, however, itis possible for a vessel to be injured to such anextent that the watertight compartments are uselessunless the doors can be closed in an instan
