Of foreign matters which have attracted attention, there is the remarkable fall of _grain_, not rain, in Belgium, a few weeks since, of a kind altogether unknown in that country. Some of it has been sown, with a view to judge of it by the plant; meanwhile, the learned are speculating as to its origin. The Dutch, pursuing their steady course of reclamation, have just added some hundreds of acres to their territory on the borders of the Scheldt; and it is said that the grand enterprise of draining the Haarlemmer-Meer is at last completed, there being nothing now left but a small running stream across the lowest part of the basin. The quantity pumped away in the last eight months of 1851, averaged a little over three inches per month, a small amount, apparently; but when it is known, that lowering the lake one inch only took away four million tons of water, we may form a fair idea of the importance of the work, and of the quantity lifted in the eight months. The depth at the beginning of this year was three feet eight inches, and this is now discharged. To have carried such a work to a successful issue, may be ranked among the greatest of engineering triumphs. To turn to another part of the world: there is something interesting from the Sandwich Islands. The king wishes to assimilate his government to that of England, to guard against the casualty of a _coup d'etat_, and a small military force has been organised for defence. The Report of the Minister of the Interior states, that 130 persons had taken the oath of allegiance within the year, of whom 66 were citizens of the United States; 31 British; 15 Chinese; and 18 of other countries. The foreign letters received and sent numbered 24,787--more than half to the United States; besides which 31,050 domestic letters were transmitted among the group of islands. There are 535 free-schools, of which 431 are Protestant, with 12,976 scholars, and 104 Roman Catholic, with 2056 scholars. There were 1171 marriages; and the population returns shew that the number of natives is still slowly on the decrease, the births among them having been 2424, while the deaths were 5792.
