Shanghai is the silk emporium of the empire. A ton of silk goods is worth from ten to fifteen thousand dollars. Nearly all of the silk is now shipped by the Peninsular and Oriental line, at a charge of $125 to $150 per ton; and notwithstanding these exorbitant rates, Shanghai merchants are compelled to make written application weeks in advance, and accept proportional allotments for shipping. In May, 1863, the screw-steamer Bahama made the trip from Foochow to London in eighty days with a cargo of tea, and obtained sixty dollars per ton, while freights by sailing vessels were but twenty dollars; the shippers being willing to pay forty dollars per ton for forty days' quicker delivery. With the Northern Pacific line constructed, the British importer could receive his Shanghai goods across this continent in fifty days, and at a rate lower than by the Peninsular line. The route by the Peninsular line runs within eighty miles of the Equator; and the entire voyage is through a tropical climate, which injures the flavor of the tea. Hence the high price of the celebrated "brick tea," brought across the steppes of Russia. The route by Puget Sound is wholly through temperate latitudes, across a smooth and peaceful sea, seldom vexed by storms, and where currents, like the Gulf Stream of Mexico, and favoring trade-winds, may be taken advantage of by vessels plying between that port and the Asiatic coast. Japan is only four thousand miles distant from Puget Sound. The teas and silks of that country are rapidly coming into market. Coal is found there, and on the island of Formosa, and up the Yang-tse. CLIMATE The climate of Puget Sound is thus set forth by an English writer, who has passed several months at Victoria:-- "From October to March we are liable to frequent rains; but this period of damp is ever and anon relieved by prolonged intervals of bright dry weather. In March, winter gives signs of taking its departure, and the warm breath of spring begins to cover the trees with tinted buds and the fields with verdure.... The sensations produced by the aspects of nature in May are indescribably delightful. The freshness of the air, the warbling of birds, the clearness of the sky, the profusion and fragrance of wild roses, the widespread, variegated hues of buttercups and daisies, the islets and violets, together with the distant snow-peaks bursting upon the view, combine in that month to fill the mind with enchantment unequalled out of Paradise. I know gentlemen who have lived in China, Italy, Canada, and England; but, after a residence of some years in Vancouver Island, they entertained a preference for the climate of the colony which approached affectionate enthusiasm."[X] The climate of the whole section through which the line passes is milder than that of the Grand Trunk line. The lowest degree of temperature in 1853--54 at Quebec was 29 below zero; Montreal, 34; St. Paul, 36; Bitter Root Valley, forty miles from Big Hole Pass, 20.
