attend to in conveying passengers and the mails across the Isthmus; so that the only means of transportation from the Atlantic States to San Francisco was round Cape Horn. Under these circumstances one can easily understand how the rates of freight advanced to extravagant figures, and created a demand under which the California clippers came into existence.
In these days of thrifty transportation by sea, when coal shovels have superseded watch-tackles, and ship-owners are expected to look cheerful with steamship rates at $14.00 a ton from New York to San Francisco, and $12.00 a ton from New York to Melbourne or Hong-kong, the rates of freight that the clipper ships earned from. New York to San Francisco seem almost incredible. In 1850 the Samuel Russell received $1.50 per cubic foot, or $60 per ton of 40 cubic feet. She registered 940 tons, and being a very sharp ship would probably carry not more than 1200 tons of California cargo. But even so, her freight would amount to $72,000, or a little more than her first cost ready for sea. The other clippers at first received the same rate, but by degrees, as they increased in tonnage and in number, the rates of freight declined to $50 per ton, and then to $40 where they remained for a considerable time.
The California clipper period covers the years 1850-1860, during the first four of which nearly all of these famous ships, numbering one hundred and sixty, were built. (See Appendix I.) Most of them were launched at or near New York and Boston, though some were built elsewhere, Richmond,
