British--both to the latest dates to which made up in a sufficiently complete shape for the object in view, and the former in some instances later than any yet published in this country, and, as believed, exclusively in our possession. We shall have to deal with masses of figures; but to the general reader in search of truth, they can hardly fail to be more acceptable than whole pages of allegations and assumptions unsupported by proof, however eloquently worked out to plausible conclusions. We commence with laying the foundation for a comprehension of the industrial progression of Russia, by a comparative statement of the average imports of a few of the chief articles of consumption, raw materials of manufacture, and manufactures, for two series, of three years each; the first series being the earliest for which official records can be cited, or were perhaps kept. Accidental circumstances, and the special influences which, favourably or unfavourably, may act upon particular years, producing at one time a feverish excess of commercial movement, and at another, a reacting depression as unnatural, are best corrected and balanced by taking averages of years. Thus, the mean term of imports for 1793, 1794, and 1795, may be thus contrasted with that for 1837, 1838, and 1839, of the following commodities:-- Annual imports, 1793-95 1837-9 Sugar, 341,356 poods 1,675,806 poods Olive oil, 42,239 ib. 345,455 ib. Machines and Instruments of all kinds, for 111,300 silver rubles 1,025,264 silver rubles Woollen cloths for 3,978,000 ib. 570,000 ib. Raw cotton, 10,000 poods 315,000 ib. Cotton-yarn, 50,000 ib. 600,000 ib. Cotton fabrics for 2,600,000 silver rubles 3,866,000 ib.
