Amber, science declares, is a kind of petrified resin, distilled by pines that were dead before the days of Adam; which is now thrown up, in stormy weather, on that remote coast, and is there fished out by the amphibious people,--who can likewise get it by running mine-shafts into the sandhills on their coast;--by whom it is sold into the uttermost parts of the Earth, Arabia and beyond, from a very early period of time. No doubt Pytheas had his eye upon this valuable product, when he ventured into survey of those regions,--which are still the great mother of amber in our world. By their amber-fishery, with the aid of dairy-produce and plenty of beef and leather, these Heathen Preussen, of uncertain miscellaneous breed, contrived to support existence in a substantial manner; they figure to us as an inarticulate, heavy-footed, rather iracund people. Their knowledge of Christianity was trifling, their aversion to knowing anything of it was great. As Poland, and the neighbors to the south, were already Christian, and even the Bohemian Czechs were mostly Converted, pious wishes as to Preussen, we may fancy, were a constant feeling: but no effort hitherto, if efforts were made, had come to anything. Let some daring missionary go to preach in that country, his reception is of the worst, or perhaps he is met on the frontier with menaces, and forbidden to preach at all; except sorrow and lost labor, nothing has yet proved attainable. It was very dangerous to go;--and with what likelihood of speeding? Efforts, we may suppose, are rare; but the pious wish being continual and universal, efforts can never altogether cease. From Henry the Fowler's capture of Brannibor, count seventy years, we find Henry's great-grandson reigning as Elective Kaiser,--Otto III., last of the direct "Saxon Kaisers," Otto Wonder of the World;--and alongside of Otto's great transactions, which were once called MIRABILIA MUNDI and are now fallen so extinct, there is the following small transaction, a new attempt to preach in Preussen, going on, which, contrariwise, is still worth taking notice of. About the year 997 or 996, Adalbert, Bishop of Prag, a very zealous, most devout man, but evidently of hot temper, and liable to get into quarrels, had determined, after many painful experiences of the perverse ungovernable nature of corrupt mankind, to give up his nominally Christian flock altogether; to shake the dust off his feet against Prag, and devote himself to converting those Prussian Heathen, who, across the frontiers, were living in such savagery, and express bondage to the Devil, worshipping mere stocks and stones. In this enterprise he was encouraged by the Christian potentates who lay contiguous; especially by the Duke of Poland, to whom such next-neighbors, for all reasons, were an eye-sorrow.
