"The great amount of labor requisite to the extraction of the returns of agriculture, will admit, at this time, of presenting but limited accounts, though, perhaps, to some extent, of the most important separate interests. "The returns of the wheat crop, for many of the Western States, will not at all indicate the average crop of those States. This is especially the case with Ohio, Indiana, and Illinois, from which, especially the former, the assistant marshals return a 'short crop,' to the extent of 50 per cent throughout the whole State. The shortness of the wheat crop in Ohio, in 1849, is verified by returns made during the subsequent season, by authority of the Legislature. The causes which affected the wheat crop in those States were not without their influence in reducing that of Western Virginia and Western Pennsylvania to some considerable extent." THE BRITISH TEA TRADE. The subject of the tea trade, in all its bearings, has been almost exhausted in former numbers of the Merchants' Magazine, but we cannot resist the temptation of publishing from the circular of MESSRS. LITTLEDALE, the subjoined table, showing its extraordinary increase in the United Kingdom : Exported. Total Total delivery of delivery. the U. Kingdom. The imports for the year, into the United Kingdom, will be about 72,000,000 lbs. against 48,300,000 lbs. in 1850. Deliveries, 59,000,000 lbs., against 56,400,000 lbs, in 1850. Stocks, 48,000,000 lbs., against 34,500,000 in 1850. We perceive here that the importations in a single year have increased 23,700,000 lbs., or an increase within 7,000,000 lbs. of the entire importations into the United States during the year 1851. IMPORT, RE-EXPORT, AND CONSUMPTION OF FOREIGN MERCHANDISE OF THE UNITED STATES, FROM 1821 To 1851. STATEMENT EXHIBITING THE VALUE OF FOREIGN MERCHANDISE IMPORTED, RE-EXPORTED, AND CONSUMED ANNUALLY, FROM 1821 TO 1851, INCLUSIVE-AND ALSO THE ESTIMATED POPULATION, AND RATE OF CONSUMPTION PER CAPITA, during the SAME PERIOD. The total value of the annual exports from Belfast, linens and linen yarns, muslins, and other cotton manufactures, cured provisions, flax and tow, &c., is about £5,600,000. The chief imports are grain, timber, flax, flaxseed, and sugar. The most important branch of Commerce is the cross-channel trade; but there is, also, an extensive trade with the United States and Canada, the West Indies, the Mediterranean, the Baltic, Archangel, and of late a limited traffic with China and the East Indies. In 1850 the shipping of the port numbered 4,490 vessels, tonnage 624,113, yielding a revenue of £29,012. The gross produce of Customs' duties during the same period was £352,658; the amount of postage collected in the town, £7,246 7s. 3d.; the stamp duties received on the Belfast collection, £26,991; and the inland revenue collected in the district, £206,278. * Nine months to June 30, VOL.

The following tabular statement is obtained through the returns made by the dep. uty inspectors to CHARLES MAYO, the inspector general of fish for the commonwealth of Massachusetts, for the year 1851, and therefore may be relied upon as correct. It shows at a glance the extent and localities of that branch of commercial enterprise, the number of vessels owned in Massachusetts and other States engaged in the mackerel fishery, and which have packed their mackerel in the State of Massachusetts, the amount of tonnage, and the number of men and boys employed on board these vessels, The whole amount of mackerel inspected in Massachusetts in 1851 was 329,242 barrels, of which amount 140,906 barrels were caught at Bay Chaleur, or in the British waters; and on the shores of the United States, or in American waters 188:36, showing a total of 329,242 barrels caught during the year 1851. The reader is referred for further information on this branch of industry, to the interesting series of papers relating to the "Fisheries of the United States" in the present and preceding numbers of the Merchants' Magazine. NAUTICAL INTELLIGENCE. TIDAL SIGNALS AT DOVOR HARBOR. Notice is hereby given, that on and after the first day of January, 1852, the following tidal signals will be exhibited at Dovor harbour instead of those now in use: Depth of water on ebb and flow by index at north pier-7 to 10 feet. Day signalsRed flag with a black ball under at the customary staff on the south pier. Night sig nals-A small low red light on the north pier, and a similar light on the outer extremity of the south pier. Depth of water on ebb and flow by index at north pier-10 to 13 feet. Day signals-Red flag on the same staff. Night signals-The lights now in use, viz.: two large red lights on the signal staffs of the south pier, and the above-mentioned small low red light on the north pier. Depth of water on ebb and flow by index at north pier-13 feet and upward. Day signals--Red flag with a black ball over on the like staff. Night signals-Lights as above. A brilliant green light projecting its rays toward the harbor's mouth will be exhibited throughout the night, by the clock-tower in the inner part of the harbor, and will show midway between the piers. No signal to ships in general will be made between seven feet at ebb and seven feet at flood, by the index board, and whenever, at other times, the harbor is inaccessible to vessels, the flag (if in the day) will be pulled down, and (if at night) the light or lights on the south pier will be extinguished, and only upon the former being rehoisted, or the latter relighted, can the harbor be entered. By order of the honorable warden and assistants of Dovor harbor, G. T. THOMPSON, Registrar. YOUGHAL LIGHT-HOUSE, SOUTH COAST OF IRELAND. A light-house has been erected on the Western side of the entrance of Youghal harbor, county Cork, from which a light was exhibited on the night of the 1st of February, 1852, and will thereafter be lighted every night from sunset to sunrise. Specification given of the position and appearance of the light by Mr. Halpin, inspector of light-houses. Youghal harbor light-house is erected on the west side and within entrance of the harbor, in lat. 51° 56' 34" N., and long. 7° 50′ 33" W., and bears From Black Rocks (East Point) N. E. 4 E., distant 2 nautic miles. From Capel (or Cable) Island (East Point) N. E. by N., distant 3 nautic miles. From Black Ball Ledge (N. E. Point) N. by W. W., distant 14 nautic miles. From Ferry Point S. W. 4 S., distant nautic miles. The lantern is 78 feet over high-water level. The light will be a fixed bright light, open to the harbor and seaward to S. W. by S., and in clear weather will be seen at the distance of two leagues. The tower is circular, of a light stone color. The bearings stated are magnetic-var. 27° 50′ W. NOTE-Capel Island, on the West side of Youghal Bay, bears from Ballycotin Island flashing light E. N., distant 6 miles, and from Mine Head intermitting light W. S., distant 12 miles CARYSFORT IRON LIGHT-HOUSE, FLORIDA REEF. This light-house is now nearly completed. The reef selected for the site of this light-house is about eighty-five miles east from Key West, and nine miles from the nearest land. A more desirable location cannot be found, as it stands on the most eastern shoal of the reef, near what is called the Elbow, and within half a mile of the unfathomable waters of the Gulf Stream. The entire structure is of iron. The plan of the base is octagonal, consisting of eight angles and one center pile of wrought iron. These piles, twenty-five feet long and eight inches in diameter, were driven by blows of a ram weighing two thousand pounds, into the solid coral bank, until an iron shoul |
