In 1829, he brought out the novel entitled the Wept of Wishton-Wish, one of the few of his works which we now rarely hear mentioned. He was engaged in the composition of a third nautical tale, which he afterwards published under the name of the Water-Witch, when the memorable revolution of the Three Days of July broke out. He saw a government, ruling by fear and in defiance of public opinion, overthrown in a few hours, with little bloodshed; he saw the French nation, far from being intoxicated with their new liberty, peacefully addressing themselves to the discussion of the institutions under which they were to live. A work which Cooper afterwards published, his Residence in Europe, gives the outline of a plan of government for France furnished by him at that time, to La Fayette, with whom he was in habits of close and daily intimacy. It was his idea to give permanence to the new order of things by associating two strong parties in its support, the friends of legitimacy and the republicans. He suggested that Henry V. should be called to the hereditary throne of France, a youth yet to be educated as the head of a free people, that the peerage should be abolished, and a legislature of two chambers established, with a constituency of at least a million and a half of electors; the senate to be chosen by the general vote, as the representative of the entire nation, and the members of the other house to be chosen by districts, as the representatives of the local interests. To the middle ground of politics so ostentatiously occupied by Louis Philippe at the beginning of his reign, he predicted a brief duration, believing that it would speedily be merged in despotism, or supplanted by the popular rule. His prophecy has been fulfilled more amply than he could have imagined--fulfilled in both its alternatives. In one of the controversies of that time, Cooper bore a distinguished part. The Revue Britannique, a periodical published in Paris, boldly affirmed the government of the United States to be one of the most expensive in the world, and its people among the most heavily taxed of mankind. This assertion was supported with a certain show of proof, and the writer affected to have established the conclusion that a republic must necessarily be more expensive than a monarchy. The partisans of the court were delighted with the reasoning of the article, and claimed a triumph over our ancient friend La Fayette, who, during forty years, had not ceased to hold up the government of the United States as the cheapest in the world. At the suggestion of La Fayette, Cooper replied to this attack upon his country in a letter which was translated into French, and, together with, another from General Bertrand, for many years a resident in America, was laid before the people of France.
