W. F. MARRIOTT, Lieutenant Colonel, Secretary to Government. The following extract from a report of a recent survey of the Cocos islands, by Lieutenant Jackson, I. N., commander of the Bengal government S. V. Krishna, is published for general information: "On the morning of the 16th I hove to off Narcondam island, with the peak bearing north (true) by azimuth, and observed its longitude west of Fort Cornwallis flagstaff, Penang, 6° 2' 48", and its latitude, deduced from observation at noon by means of two patent log distances, 13° 27' north; the height above the level of the sea being 2,150 feet, and the variation 3° easterly. "From the above observations I find that Narcondam is placed about fourteen miles too far north in the chart of the Bay of Bengal, published by Messrs. Allen & Co., in London, 8th September, 1857. This is obviously an oversight, as the latitude here given agrees with that of former observers." By order. JOHN G. REDDIE, Officiating Sec'y to the Government of India, Marine Department.

Table showing the mean annual prices of wheat per hectolitre in various countries, from 1827 to 1858, inclusive. Table showing the breadth of culture, yield per hectare, and amount, of wheat produced in France, from 1815 to 1858, inclusive. acres. 1 hectare is equal to about 2 acres, or, more accurately, 24 1 hectolitre is equal to about 25 Winchester bushels, or, more accurately. 283791 bushels. 1 hectolitre is also equal to about 23 imperial bushels, or, more accurately, 2751 bushels By inspecting this table it will be seen that the breadth of culture of wheat in France increased within a period of forty-three years more than 2,000,000 of hectares, or 5,060,922 acres, and that the annual yield per hectare nearly doubled within that time, the increase of the amount harvested being 200,154,319 bushels. From 1815 the main yield was 105 hectolitres per hectare; from 1826 to 1836 it was 12,35 hectolitres; from 1836 to 1845 it was 13 hectolitres; and from 1846 to 1857 it was 131 hectolitres per hectare.
