On our passage to New York we met with no remarkable occurrence, and saw not a cruiser of any nation. On reaching the city, we found that an extraordinary excitement prevailed. War had been declared against Great Britain; an American fleet under Commodore Rodgers had sailed the day before on a cruise. The frigate Essex was at Brooklyn with a complete and gallant crew, and her commander, Captain Porter, was making preparations for an immediate departure. This brave officer made no secret of his intention to bring the enemy to close quarters whenever a chance offered, and proclaimed throughout the frigate that any man who repented having shipped might receive his discharge.

One man only of the hundreds composing the crew availed himself of the captain's proclamation, under the plausible pretext that he was an Englishman. But it having been ascertained that so far from being a loyal subject of the king of Great Britain, he was a native-born Yankee with a cowardly spirit, his shipmates were so indignant that they tarred and feathered him, carried him over to New York, placed a placard on his breast, formed a procession, and paraded him through the streets.

There was a great bustle about the wharves in New York, although of a different kind from that which prevailed two months previous in consequence of the embargo. Clippers of all kinds and sizes were bought up at enormous prices, and rapidly transformed into privateers and letters of marque. Heavy guns, instead of bales of goods, were dragged through the streets by dray horses, and muskets, cutlasses, and boarding pikes met the eye at every turn. Fierce-looking men with juvenile mustachios jostled each other in the streets, and even the dapper clerks and peaceable artisans swore deeper oaths and assumed more swaggering airs. News of naval battles was anxiously looked for, startling rumors of all kinds were afloat, and every vessel which arrived was supposed to be fraught with momentous intelligence respecting the cruisers on the coast. I noted these proceedings, caught the spirit of enthusiasm, and sympathized in the excitement which so universally prevailed. I told Captain Thompson I had made up my mind to join a privateer. To this remark the worthy skipper made no reply but by a smile, which I interpreted as an approval of my determination.

One of my first acts, however, was to call on Hansen, the keeper of the boarding house where I had formerly resided, and discharge my debt. I resumed possession of my chest and books, which I regarded as my greatest treasure. I had recovered from my lameness. I was strong and active, and although poorly off for clothing or worldly goods, was free from debt, and had a couple of dollars which I could call my own. My condition had decidedly improved; the prospect ahead began to brighten, and I felt able and anxious to perform a manly part in any noble enterprise.

I took an early opportunity to look around the wharves, and examine the privateers that were getting ready for a cruise. Two of these vessels particularly commanded my admiration, the Teaser and the Paul Jones. The Teaser was a New York pilot boat of ninety tons burden, a rakish, wicked-looking clipper enough. Her armament consisted chiefly of one long eighteen-pounder amidships. The Paul Jones was a large schooner of two hundred and twenty tons, heavily rigged, with immense spars, a spacious deck, and of a genuine buccaneer model. The armament of this privateer consisted of one long twenty-four-pounder and twelve heavy carronades.

After the deliberation I fixed upon the Paul Jones as the more desirable vessel. The warlike preparations and rakish appearance of this schooner looked like BUSINESS, and I had seen the insolence of John Bull so often exhibited on the broad highway of nations, and had so often listened to his taunts and sneers in ridicule of the prowess of the Yankees, that I longed for an opportunity to lend a hand to give him a drubbing. I stepped on board and inquired of an officer who seemed busy in giving directions, if I could have a chance in the privateer. He asked me a few questions, to which I gave satisfactory answers. He said there were many applications of a similar character, but he thought he could insure me a situation; told me to call next day at two o'clock, when the agent would be on board, and the matter could be arranged.

The important part which the American privateers bore in the last war with Great Britain is well known. They were fitted out in every port, manned by brave and active men, and heavily armed. Managed with seaman-like dexterity, and superior in sailing capacity to vessels belonging to any other nation, they could not be easily captured. The injury inflicted on the commerce of Great Britain by these privateers is incalculable. They carried terror among our enemies in the remotest parts of the ocean, and the desire of the British government to put an end to the war may, in part, be attributed to the activity, courage, and enterprise of our privateers. The principle has been adopted in all ages, that private property, captured on the high seas, is a lawful prize to the captors; also, that the destruction of private property belonging to an enemy is a justifiable act. To a well-constituted mind it must appear, on investigation, that such principles are unjust, belong to a barbarous age, and cannot be advocated on any platform of ethics recognized among civilized nations in modern times.

An attempt was made within a few years on the part of Great Britain, which also met the approval of the French government, TO ABOLISH THE PRIVATEER SYSTEM, on the ground that this mode of warfare is wrong in principle, irregular subject to abuses, and to a certain extent irresponsible. A proposition was made to our government to be a party to an agreement to abolish the system forever. Under the cloak of Christian philanthropy this was a master stroke or policy on the part of the British and French governments. Should the privateer system be abolished and a war unhappily take place between this country and France or Great Britain, either of those nations, with myriads of heavily armed men-of-war, could overrun the ocean, and every American merchantman venturing to sea would be captured or burned; our own commerce would be annihilated, while OUR FEW NATIONAL SHIPS, scattered over a large surface, could offer but little check to the commercial pursuits of an enemy.

Our government met the proposition in a manly manner, and while it declined entering into any agreement which had for its exclusive object the abolition of the privateer system, a measure which would inure chiefly to the advantage of Great Britain or France, it went further, and declared itself ready to accede to any arrangement by which, during a war, private property of every character should be exempted from capture, not only by privateers but NATIONAL VESSELS. This noble suggestion, worthy a great nation in an enlightened age, did not meet the views of our friends across the water. This broad Christian principle, if carried out, would deprive them of many advantages they might reasonably expect to derive from their numerous ships of war.

It must be evident that in case of a war between this country and a mighty naval power, which we trust will never occur, the many large "clipper ships," which compose a large portion of our commercial marine, will be provided with screw propellers, and transformed into privateers. Armed with guns of the heaviest metal, unequalled in speed, and able to select their distance and position, they will prove a formidable means of defence and aggression; and will do much towards protecting our own commerce while they will destroy that of the enemy.
