February 19.—The Supreme Court of the United States has before it the prize cases resulting from captures made by our navy. The counsel for the English and rebel blockade-runners and pilferers find the best point of legal defence in the unstatesmanlike and unlegal wording of the proclamation of the blockade, as concocted and issued by Mr. Seward, and in the repeated declarations contained in the voluminous diplomatic correspondence of our Secretary of State,—declarations asserting that no war whatever is going on in the Federal Republic. No war, therefore no lawful prizes on the ocean. So ignorance, and humbug mark every step of this foremost among the pilots of a noble, high-minded, but too confiding people.

The facts, the rules, and the principles in these prize cases are almost unprecedented and new; new in the international laws, and new in the history of governments of nations. Seldom, if ever, were so complicated the powers of government, its rights, and the duties of neutrals, the rights and the duties of the captors, and the condition of the captured. This rebellion is, so to speak, sui generis, almost unprecedented on land and sea. The difficulties and complications thus arising, became more complicated by the either reckless or unscientific (or both) turn given by the State Department in conceding to the rebels the condition of belligerents. Thus the great statutory power of the sovereign, (that is, of the Union through its president) for the suppression of the rebellion was palsied at the start. The insurrection of the Netherlands alone has some very small similarity with our civil war; however, that insurrection took place at a time when very few, if any, principles of international laws were generally laid down and generally recognized. Here the municipal laws, the right of the sovereign and his duty to save itself and the people, the rights and the laws of war, wrongly applied to such virtual outlaws as the rebels, the maritime code of prize laws and rules, play into and intertwine each other. When Mr. Seward penned his doleful proclamation of the blockade, etc., he never had before his mind what a mess he generated; what complications might arise therefrom. I am sure he never knew that such proclamation was a priori pregnant with complications, and that at least its wording ought to have been very careful. Mr. Seward was not at all cognizant of the fact that the wording of a proclamation of a blockade, for the time being, lays down a rule for the judges in the prize courts. For him it was rather a declamation than a proclamation; he who believed the rebellion would end in July, 1861, and that no occasion would arise to apply the rules of the blockade.

Thus Mr. Seward, with his thorough knowledge of international law rendered difficult the position of the captors; he equally increased the difficulty for the judge to administer justice. By this proclamation and the commentaries put on it, Mr. Seward curtailed the rights of the government of which he is a part, conceded undue conditions to the rebels, and facilitated to the neutrals the means of violating his blockade. So much is clear and palpable to-day, and I am sure more complications and imbecilities are in store. If Mr. Seward had had good advisors for these nice and difficult questions, he would not have blundered in this way. Thus Charles Eames, who in the pleadings before the Superior United States Court has shown a consummate mastery in prize questions—Eames could teach Mr. Seward a great deal about the constitutional powers of the president to suppress the rebellion, and about the meaning and the bearing of international maritime laws, rights, duties and rules.

February 20.—A Mr. Funk, a member of the Illinois Senate, a farmer, and a man of sixty-five years, on February 13, made a speech in that body which sounds better than all the rhetories and oratories. It was the sound and genuine utterance of a man from the people, and I hope some future historian will record the speech and the name of the old, indomitable patriot.

February 20.—Stimulated by a pure Athenian breeze, the Congress passed a law organizing an Academy of Sciences. What a gigantic folly; the only one committed by this Congress. The pressure was very great, and exercised by the bottomless vanity of certain scientific, self-styled magnates, and by the Athenians. Up to this day, the American scientific development and progress consisted in its freedom and independence. No legal corporation impeded and trammeled the limitless scope of the intellectual and scientific development. That was the soul and secret of our rapid and luminous onward march. Now fifty patented, incorporated respectabilities will put the curb on, will hamper the expansion. Academies turn to fossils. My hope is that the true American spirit will soar above the vanity and pettiness of corporated wisdom, and that this scientific Academy bubble will end in inanity and in ridicule. I am sorry that Congress was taken in, and committed such a blunder. It was caught napping.

Mr. Chase's bank bill, prospective of money, and as many say, prospective of presidency, passed the house. What fools are they already begin to direct their steps and their ardent wishes toward the White House.

February 22.—The, at any price, supporters of the Administration, point with satisfaction to the various successes, and to the space of land already redeemed from rebellion. I protest against such explanation given to events, and call to it the attention of every future historian. Never had the suum cuique required a more stringent, philosophical application. With the various inexhaustible means at its disposal, with the unextinguishable enthusiasm of the people, far different and more conclusive results, could and ought to have been obtained. The ship makes headway if even, by the negligence of the officers and of the crew, she drags a cable or an anchor. The ship is the people dragging its administrators.

A western Democrat, but patriot, said to me that Lincoln compares to Jeff Davis, as a wheel-barrow does to a steam engine!

The Democrats claim to be the genuine fighting element, and to be possessed of the civic courage, and of governmental capacity. How, then, can the Democrats rave for McClellan, the most unfighting soldier ever known?

The future historian must be warned not to look to the newspapers for information concerning facts and concerning the spirit of the people. The Tribune's senile clamor for peace, for arbitration, for meditation, its Jewitt, Mercier, Napoleon, and Switzerland combinations, fell dead and in ridicule before the sound judgment of ninety-nine hundredths of the people.
