As many as fifty thousand ships of all classes enter and leave the Thames in twelve months, or about seventy vessels per day, exclusive of all the innumerable kinds of miscellaneous small craft. The entire French commercial navy consists of twelve thousand vessels, an aggregate of perhaps one million seven hundred thousand tons, a little more than a quarter of the number of ships and the same percentage of tonnage that enters and leaves this world metropolis of London. If the ships that move to and fro on the bosom of the Thames be supposed to average one hundred and fifty feet in length one with another, they would reach, placed stem and stern together, upward of thirteen hundred miles, or nearly half way across the Atlantic. The Custom House duties, with a very low tariff for the port of London, during one year amounts to sixty-eight millions of dollars in gold, and the declared real value of exports from London for the same time amounted to one hundred and seventy millions of dollars in gold. The declared real value of the imports registered at the huge granite custom house on the Thames, for the port of London, for 1869, from foreign and colonial ports, was four hundred millions of dollars in gold, or as much as the total value of the real estate on New York island in 1870. Englishmen are very fond of coffee it seems, for they imported thirty million pounds of the fragrant berry in 1869. The choleric temper of the people may find an explanation in the six million pounds of pepper received in London. London also imported seven million gallons of rum, although it is supposed to be the great beer drinking city of the world. Eighty thousand gallons of gin, sixty million pounds of tea, thirty-eight million pounds of tobacco, nine million six hundred and fifty-seven thousand and thirty-four gallons of foreign wines, two million cwts. of raw sugar, and two million seven hundred sixty-two thousand two hundred and forty-eight gallons of brandy were imported in 1869. These articles of merchandise were all held in bond at the London Custom House, and from these figures my readers may form some idea of the magnitude of the commerce of this great city. Russia sent one thousand three hundred vessels and received three hundred and ninety-one vessels, Sweden one thousand one hundred and twenty-one vessels and received five hundred and twenty vessels, France sent one thousand four hundred and sixteen vessels and received one thousand three hundred and eighty-two vessels, Holland sent nine hundred and twenty-four vessels and received seven hundred and fourteen vessels, Cuba sent three hundred and twelve vessels and received sixty-two vessels, United States sent four hundred and twelve vessels and received three hundred and seventeen vessels, China sent two hundred and eight vessels and received one hundred and thirty vessels in 1869.
