ROCHESTER FLOUR TRADE. QUANTITY OF FLOUR SHIPPED FROM ROCHESTER IN EACH MONTH OF THE SEASON OF 1851, COMPARED WITH FOUR PREVIOUS YEARS, AS PUBLISHED IN THE ROCHESTER DEMOCRAT. The Rochester and Syracuse Railroad carried 20,513 barrels in 1851. This is a small comparative amount. In 1848 that road took 58,137 barrels, and in 1850 about 30,000 barrels. The amount of flour left here by canal during the year is 26,888 barrels. Last year there were 44,443 barrels left by canal. The Western Railroad during 1851 brought down 49,000 barrels, in 1850, a little more than that. Adding to the amount shipped by canal, the difference in the amount left here during the year, and the shipments are still less than any previous year named, excepting 1844-5. To the amount shipped must be added the amount consumed by 40,000 inhabitants, and by a large number of people living in the suburbs and vicinity. The amount of wheat left here by both canals for two years is as follows :— The following is the quantity left by both canals for a series of years:— The Western Railroad has left 175,000 bushels, which is more by 50,000 than it brought here the year previous. A rough estimate of the amount of flour manufactured here in the course of a year is 600,000 barrels, to manufacture which, computing five bushels of wheat to each barrel, would require three million bushels. The whole amount left here by canal and railroad is 1,640,454 bushels, leaving 1,359,546 to be made up from receipts by wagons from the country towns. The product of this county is computed at about that amount. A considerable portion of what is grown in this county is brought in by canal, while no small amount is brought from adjoining counties by land carriage. Some wheat is received by lake vessels, both from Canadian and American ports. The amount arriving last year is much smaller than usual, but we have not been able to obtain the precise figures. Canadian produce dealers have found this an unprofitable market, as their wheat can scarcely compete with Genesee upon paying terms, and they do not often venture to send a cargo to our port. BRITISH IMPORTS OF SUGAR FROM HER POSSESSIONS. From a return, printed by order of the British House of Commons, we find that in 1851, 36,777,717 lbs. of sugar were imported from British Possessions, which, as compared with the previous year's imports, shows a decrease of 2,955,326 lbs. Of coeoa 4,349,051 lbs. were imported, being an increase over the previous year of 2,360,454 lbs. Cotton wool was imported to the extent of 123,075,603 lbs., exceeding the imports of 1850 by 3,974,948 lbs. The imports of foreign sugar from all parts amounted last year to 2,296,304 cwts., being more than the previous year by 945,781 cwts. Refined sugar, foreign, was imported to the amount of 53,084 cwts., and of British produce 153 cwts. The sugar imported from British possessions amounted to 5.693,082 cwts. The imports of rum from British possessions amounted to 4,652,232 gallons, being a small increase over the previous year. COMMERCE OF HOLLAND IN 1852. By a comparative statement of the imports, exports, and transit of merchandise in Holland during the first six months of 1852, published in the Staats Courant, it is shown that the quantity of raw cotton imported in that period is nearly double that imported in the same period of 1851. Cotton yarn also shows an increase of fully one-third; the value of iron imported has been increased by nearly 1,500,000 florins; the quantity of raw sugar, 15,000,000 lbs.; coffee, 10,000,000 lbs.; rice, 6,000,000 lbs.; leaf tobacco, 6,000,000 lbs.; and tin by 1,000,000 lbs. In the exports there has been an increase of 1,200,000 florins' value upon iron, 3,000,000 lbs. upon raw cotton, 8,000,000 lbs. upon coffee, 1,000,000 lbs. upon sundry manufactured goods, 6,500,000, lbs. upon rice, 600,000 lbs. upon sugar, 6,000,000 lbs. upon leaf tobacco, and 1,000,000 lbs. upon cotton yarns. THE FOREIGN TRADE OF LONDON. It appears from a return to Parliament, that in 1841 the number of British vessels which had entered the port of London, engaged in the foreign trade, was 4,016 sailing and 626 steamers, and in ten years-in 1851-the number was 5,190 sailing and 1,403 steamers; while of foreign vessels there were, in 1841, 1,927 sailing and 72 steamers, and last year the number had increased to 3,474 sailing and 274 steam vessels. NAUTICAL INTELLIGENCE. BELVIDERE KNOLL AND HOOPER'S STRAITS. The Superintendent of the United States Coast Survey has communicated to the Secretary of the Treasury the following information, which was published officially for the benefit of mariners: COAST-SURVEY STATION, near Petersburg, Va., August 7, 1852. SIR-I have the honor to communicate a notice to mariners in relation to buoys recently placed, by request of the collector of Baltimore, on the Belvidere Knoll, near the entrance to the Patapsco, and near a wreck in Hooper's Straits, and respectfully ask authority to publish it. A buoy painted red, with a white band near the top of the spar, has been placed near the sunken wreck of a collier, in the entrance of Hooper's Straits, (Chesapeake Bay,) which is a dangerous impediment to vessels entering the straits from the northward. The buoy is placed in seventeen feet water, seven yards from the bows of the wreck, with the following bearings by compass:— Light-ship in Hooper's Straits.... Tom's point.. E. by S. N. W. Vessels should pass to the westward of the buoy, and approach it no nearer than thirty yards. A similar buoy has been placed on Belvidere Knoll, S. E. from the Bodkin, (Chesapeake Bay,) and east of the swash channel, into Patapsco River, (Baltimore entrance,) with the following bearings by compass: Bodkin's Light-house. N. W. N. Very respectfully, yours, &c., A. D. BACHE, Superintendent. BEACON AT ENTRANCE OF BOMBAY HARBOR. COMMODORE'S OFFICE, BOMBAY, May 19, 1852. The beacon on the Island of Kennery, situate at the entrance of Bombay Harbor, the completion of which was made known by a notification published in the Bombay Government Gazette, and dated April 3d, 1851, having been partially destroyed by the heavy rains of the monsoon, was taken down. A new beacon has since been commenced on, and is now sufficiently advanced towards completion to be visible to vessels approaching the harbor, and it is expected will be entirely finished by the 1st of June next. The new beacon is of a cylindrical form, and rises to the hight of 70 feet above the foundation. The beacon is painted black, and can be seen at a distance of 16 miles on a clear day. The following are a few of the bearings from Kennery : The following notice to mariners is extracted from a letter of Lloyds' agent at Callao, dated June 25th, 1852: "The channel (Boqueron) is not the usual one to enter the port, and lately a number of vessels have come on shore from attempting to come in that way, rather than the ordinary one round the north point of the island of San Lorenzo. The Pe ruvian vessels generally enter by the former channel, but most of them are small, and the masters are, by practice, well acquainted with it. The Peruvian government have prohibited vessels laden with guano from entering by the Boqueron Channel, and as it is not a safe one for persons unacquainted with it, we consider that the underwriters and masters of vessels should be aware of the risk and danger incurred." BEARINGS OFF BULL'S BAY LIGHT-HOUSE. Bring the light-house on the north-east of Bull's Island to bear N. W. W. by compass, and run for it until over the bar, then follow the beach round by the lead, until the point of the island gives you a harbor. This course will give you not less than nine feet on the bar at low tide, rise of tide about six feet. LIGHT-HOUSE ON BULL'S ISLAND. The light-house lately constructed on Bull's Island, about 30 miles north of Charleston, was lighted on the 1st of August. Bull's Bay affords a safe anchorage ground for vessels of light draft, which may be obliged to seek a safe harbor by stress of weather. W. J. GRAYSON, Superintendent. NOTICE TO UNITED STATES CONSULS. Our consuls abroad will serve the interest of Commerce and Navigation by forwarding to the Editor of the Merchants' Magazine any authentic information touching lighthouses, port charges, &c., &c. COMMERCIAL REGULATIONS. SPANISH COMMERCIAL REGULATIONS. We are enabled, through ALEXANDer Burton, Esq., United States Consul at Cadiz, Spain, to lay before the readers of the Merchants' Magazine the subjoined information in relation to the Spanish tariff of 1849, &c. : The Spanish Custom-House Tariff of 1849 has undergone modifications in the names of some articles of importation, principally of European manufacture, as also in regard to the duties payable thereon, of all which the Spanish Government has recently ordered the publication. The decree of 17th December last, relative to port dues on vessels arriving in Spain, went into operation the 1st of February last. The shipping of the United States continues subject to the payment of the followlowing duties: Light-house, 2 reals; anchorage, 2 reals; loading, 5 reals; unloading, 5 reals; per ton of 2,000 pounds Spanish; and one-eighth is added to the English tonnage of 20 cwt., to reduce it to the Spanish ton of 20 quintals. Anchorage and light money to be paid at the port first touched at; loading and unloading as often as either takes place. Vessels coming strictly in ballast, and loading salt at Cadiz, are exempt from light duty, but subject to the payment of all the other dues. A consumption duty is levied on the provisions brought into port by vessels and used on board by their crews and passengers. This duty may be assessed on difference between the quantity of provisions manifested at time of entry and what may exist at the time of clearing, duty being charged on the excess; but in order to avoid such a vexatious inspection, it is permitted, by agreement with the Administration of Contributions, to compound at four marvedis per day for each person on board. The sanitary regulations in regard to quarantine remain without alteration since December 31st, 1850. The pilotage from and to sea, and also the health office, charges for visitor and tender on vessels and cargo; and searchers' fees are regulated by a tariff of fifty years' standing. A royal order of the 25th of April, explanatory of that of 17th of December last, says, that the charges for anchorage, loading and unloading, are to be exacted from vessels in all ports of the Peninsula; and by ports is to be understood those points of the coast where artificial works may have been constructed, to afford shelter and se cure means of loading, without more exception than roadsteads and open bays (radas y calas abiestas). Under this order of the 25th of April, the chief of the custom-house at Algeciras has given notice to the foreign vice-consular agents there resident, that the anchorage duty will be exacted from all foreign vessels entering that bay for shelter or other cause (arribada forzosa); and claims the delivery of manifests and crew lists. The object is probably to oblige all wind-bound vessels so anchoring, and without performing any mercantile operation, to enter and clear at the custom-house, thus causing delay and increase of expenses, ruinous to voyages of vessels with cargoes of fruit and other perishable articles. TREATY OF COMMERCE AND NAVIGATION, BETWEEN THE U. S. & GUATEMALA. BY THE PRESIDENT OF THE UNITED STATES OF AMERICA. Whereas a General Convention of Peace, Amity, Commerce, and Navigation, between the United States of America and the Republic of Guatemala, was concluded and signed in the city of Guatemala, by the respective Plenipotentiaries, on the third day of March, in the year of our Lord one thousand eight hundred and forty-nine; which Convention, being in the English and Spanish languages, is, word for word, as follows: General Convention of peace, amity, Commerce and navigation, between the United States of America and the republie of Guatemala. The United States of America and the republic of Guatemala, desiring to make firm and permanent the peace and friendship which happily prevails between both nations, have resolved to fix, in a manner clear, distinct, and positive, the rules which shall in future be religiously observed between the one and the other, by means of a treaty or general convention of peace, friendship, commerce and navigation. For this most desirable object, the President of the United States of America has conferred full powers on Elijah Hise, charge d'affaires of the United States near this republic, and the Executive Power of the republic of Guatemala on the Sr. Ldo D. Jose Mariano Rodriguez, Secretary of State and of the Department of Foreign Relations, who, after having exchanged their full said powers in due and proper form, have agreed to the following articles: ARTICLE I. There shall be a perfect, firm, and inviolable peace and sincere friendship between the United States of America and the republic of Guatemala, in all the extent of their possessions and territories, and between their people and citizens, respectively, without distinction of persons or places. ART. II. The United States of America and the republic of Guatemala, desiring to live in peace and harmony with all the other nations of the earth, by means of a policy frank and equally friendly to all, engage mutually not to grant any particular favor to other nations, in respect of Commerce and navigation, which shall not immediately become common to the other party, who shall enjoy the same freely, if the concession was freely made, or on allowing the same compensation, if the concession was conditional. ART. III. The two high contracting parties, being likewise desirous of placing the commerce and navigation of their respective countries on the liberal basis of perfect equality and reciprocity, mutually agree that the citizens of each may frequent all the coasts and countries of the other, and reside and trade there in all kinds of produce, manufactures and merchandise, and they shall enjoy all the rights, privileges, and exemptions in navigation and commerce which native citizens do or shall enjoy; submitting themselves to the laws, decrees, and usages there established, to which native citizens are subjected. But it is understood that this article does not include the coasting trade of either country, the regulation of which is reserved to the parties, respectively, according to their own separate laws. ART. IV. They likewise agree, that whatever kind of produce, manufacturer, merchandise of any foreign country can be from time to time lawfully imported into the United States in their own vessels, may be also imported in vessels of the republic of Guatemala; and that no higher or other duties upon the tonnage of the vessels or her cargo shall be levied and collected, whether the importation be made in vessels of the one country or the other: and, in like manner, that whatever kind of produce, manufacture, or merchandise of any foreign country can be from time to time lawfully imported into the republic of Guatemala in its own vessels, may be also imported in vessels of the United States; and that no higher or other duties upon the tonnage of the vessel or her cargo shall be levied and collected, whether the importation be made in vessels of the one country or of the other. And they further agree, that whatever may be lawfully exported or re exported from the one country in its own vessels to any foreign country, may be in like manner exported or re-exported in vessels of the other country. And the same bounties, duties, and drawbacks shall be allowed and collected, whether such exportation or re-exportation be made in vessels of the United States or of the republic of Guatemala. ART. V. No higher or other duties shall be imposed on the importation into the United States of any articles the produce or manufactures of the republic of Guatemala, and no higher or other duties shall be imposed on the importation into the republic of Guatemala of any articles the produce or manufactures of the United States, than are or shall be payable in like articles being the produce or manufactures of any other foreign country; nor shall any higher or other duties or charges be imposed in either of the two countries on the exportation of any articles to the United States or to the republic of Guatemala, respectively, than such as are payable on the exportation of the like articles to any other foreign country; nor shall any prohibition be imposed on the exportation or importation of any articles the produce or manufac tures of the United States or of the republic of Guatemala, to or from the territories of the United States, or to or from the territories of the republic of Guatemala, which shall not equally extend to all other nations. ART. VI. It is likewise agreed, that it shall be wholly free for all merchants, commanders of ships, and other citizens of both countries, to manage themselves their own business in all the ports and places subject to the jurisdiction of each other, as well with respect to the consignment and sale of their goods and merchandise, by wholesale or retail, as with respect to the loading, unloading, and sending off their |
