Though the Philadelphia line of steamers has much to contend against, owing to duties imposed by the American Government on all articles required for their construction and outfit, and may, consequently, find it difficult to rival successfully the steam-ships of Europe engaged in the Transatlantic trade, they are supported, if not owned, by one of the largest railway undertakings in the United States of America. The lines of this company cover more than 6000 miles of communication within the interior, extending over States which produce the breadstuffs of the north as well as the tropical fruits of the south with a teeming and almost virgin soil, sufficient in itself to produce cargoes for a fleet of ships far in excess of that it as yet possesses, and affording fields of remunerative employment for hundreds of thousands of persons now huddled together in many of the over-peopled countries of Europe. Indeed, from the accounts which reach us, the valley of the Mississippi in itself still affords room, and, in time, will give profitable employment for 100,000,000 persons, and if the industrious and frugal of our own people and of Europe, are unable to gain a living by honest means in the land of their birth, they will find, sailing daily from the port of Liverpool, alone, at the present moment, as also from other ports, steam-ships[267] of the finest description, ready to convey them in a hitherto incredibly short space of time, to the United States of America, and at a cost very little more than they would require for their maintenance at home, during a similar period of time to that occupied on the passage. [Sidenote: Anchor line from the Clyde, 1856.] But, besides the magnificent lines of steamers which now connect, _viâ_ Liverpool, the Old and New Worlds together by a ferry, easier of accomplishment, and attended with less danger than was even the passage between England and France half a century ago, there are other important lines of steamers from Glasgow and London, as well as from various continental ports, which I must notice. Not the least important of these is the Anchor line from the Clyde, one of the many extraordinary developments, during recent years, of our maritime power, and entirely due to individual energy. Within only a few years Messrs. Henderson Brothers, the managing owners of the Anchor line, have created a fleet of steamships of 71,328 gross tons and of 15,147 horse-power.[268] [Sidenote: Prodigious range of their trade operations.]
