The practical person set forth in an elaborate memoir that the Hollanders were making rapid progress in commerce, arts, and manufactures, while the obedient provinces were sinking as swiftly into decay. The Spanish Netherlands were almost entirely shut off from the sea, the rivers Scheldt and Meuse being hardly navigable for them on account of the control of those waters by Holland. The Dutch were attracting to their dominions all artisans, navigators, and traders. Despising all other nations and giving them the law, they had ruined the obedient provinces. Ostend, Nieuwpoort, Dunkerk were wasting away, and ought to be restored. "I have profoundly studied forty years long the subjects of commerce and navigation," said the practical person, "and I have succeeded in penetrating the secrets and acquiring, as it were, universal knowledge-- let me not be suspected of boasting--of the whole discovered world and of the ocean. I have been assisted by study of the best works of geography and history, by my own labours, and by those of my late father, a man of illustrious genius and heroical conceptions and very zealous in the Catholic faith." The modest and practical son of an illustrious but anonymous father, then coming to the point, said it would be the easiest thing in the world to direct the course of the Scheldt into an entirely new channel through Spanish Flanders to the sea. Thus the Dutch ports and forts which had been constructed with such magnificence and at such vast expense would be left high and dry; the Spaniards would build new ones in Flanders, and thus control the whole navigation and deprive the Hollanders of that empire of the sea which they now so proudly arrogated. This scheme was much simpler to carry out than the vulgar might suppose, and, when. accomplished, it would destroy the commerce, navigation, and fisheries of the Hollanders, throwing it all into the hands of the Archdukes. This would cause such ruin, poverty, and tumults everywhere that all would be changed. The Republic of the United States would annihilate itself and fall to pieces; the religious dissensions, the war of one sect with another, and the jealousy of the House of Nassau, suspected of plans hostile to popular liberties, finishing the work of destruction. "Then the Republic," said the man of universal science, warming at sight of the picture he was painting, "laden with debt and steeped in poverty, will fall to the ground of its own weight, and thus debilitated will crawl humbly to place itself in the paternal hands of the illustrious house of Austria." It would be better, he thought, to set about the work, before the expiration of the Truce. At any rate, the preparation for it, or the mere threat of it, would ensure a renewal of that treaty on juster terms. It was most important too to begin at once the construction of a port on the coast of Flanders, looking to the north.
