The country was now becoming more pleasing in character, and many of the islands, as I floated past them on the current, gave evidence of great fertility where cultivation had been bestowed upon them. Some of these islands were connected to one shore of the river by low dams, carelessly constructed of stones, their purpose being to deepen the channel upon the opposite side by diverting a considerable volume of water into it. When the water is very low, the tops of these dams can be seen, and must, of course, be avoided by boatmen; but when the Ohio increases its depth of water, these artificial aids to navigation are submerged, and even steamboats float securely over them.

On Wednesday the river began to rise, in consequence of the heavy rains; so, with an increased current, the duck-boat left her quarters about eleven o'clock in the forenoon. Early in the afternoon, Parkersburgh, situated at the mouth of the Little Kanawha River, in Virginia, came into view. This is the outlet of the petroleum region of West Virginia, and is opposite the little village of Belpr, which is in the state of Ohio. These towns are connected by a massive iron bridge, built by the Baltimore and Ohio Railroad Company.

Two miles below Belpr lay the beautiful island, formerly the home of Blennerhasset, an English gentleman of Irish descent, of whom a most interesting account was given in a late number of Harper's Magazine. Mr. Blennerhasset came to New York in 1797, with his wife and one child, hoping to find in America freedom of opinion and action denied him at home, as his relations and friends were all royalists, and opposed to the republican principles he had imbibed. Here, on this sunny island, under the grand old trees, he built a stately mansion, where wealth and culture, combined with all things rich and rare from the old world, made an Eden for all who entered it.

Ten negro servants were bought to minister to the daily needs of the household. Over forty thousand dollars in gold were spent upon the buildings and grounds. A telescope of high power to assist in his researches, books of every description, musical instruments, chemical and philosophical apparatus, everything, in fact, that could add to the progress and comfort of an intellectual man, was here collected. Docks were built, and a miniature fleet moored in the soft waters of the ever-flowing Ohio. Nature had begun, Blennerhasset finished; and we cannot wonder when we read of the best families in the neighboring country going often thirty and forty miles to partake of the generous hospitality here offered them. Mrs. Blennerhasset, endowed by nature with beauty and winsome manners, was always a charming and attractive hostess, as well as a true wife and mother.

For eight years Blennerhasset lived upon his island, enjoying more than is accorded to the lot of most mortals; but the story of his position, his intelligence, his wealth, his wonderful social influence upon those around him, reached at length the ear of one who marked him for his prey.

Aaron Burr had been chosen vice-president of the United States in 1800, with Thomas Jefferson as president; but in 1804, when Jefferson was re-elected, Burr was not. The brain of this brilliant but ill- balanced and unprincipled man was ever rife with ambitious schemes, and the taste of political power in his position as vice-president of the United States seemed to have driven him towards the accomplishment of one of the boldest and most extravagant dreams he ever imagined. Mexico he thought could be wrested from Spain, and the then almost unpeopled valleys of the Ohio and Mississippi taken from the United States. This fair region, with its fertile soil and varied climate, should be blended into one empire. On the north, the Great Lakes should be his boundary line, while the Gulf of Mexico should lave with its salt waters his southern shores. The high cliffs of the Rocky Mountains should protect the western boundary, and on the east the towering Alleghanies form a barrier to invading foe.

Such was the dream, and a fair one it was. Of this new empire, Aaron Burr would of course be Imperator; and the ways and means for its establishment must be found. The distant Blennerhasset seemed to point to the happy termination of at least some of the difficulties. His wealth, if not his personal influence, must be gained, and no man was better suited to win his point than the fascinating Aaron Burr. We will not enter into the plans of the artful insinuator made to enlist the sympathies of the unsuspecting Englishman, but we must ever feel sure that the cloven foot was well concealed until the last, for Blennerhasset loved the land of his adoption, and would not have listened to any plan for its impoverishment. His means were given lavishly for the aid of the new colony, as Burr called it, and his personal influence made use of in enlisting recruits. Arms were furnished, and the Indian foe given as an excuse for this measure.

Burr during this time resided at Marietta, on the right bank of the river, fifteen miles above Blennerhasset's Island. He occupied himself in overseeing the building of fifteen large bateaux in which to transport his colony. Ten of these flat-bottomed boats were forty feet long, ten feet wide, and two and a half feet deep. The ends of the boats were similar, so that they could be pushed up or down stream. One boat was luxuriously fitted up, and intended to transport Mr. Blennerhasset and family, proving most conclusively that he knew nothing of any treasonable scheme against the United States.

The boats were intended to carry five hundred men, and the energy of Colonel Burr had engaged nearly the whole number. The El Dorado held out to these young men was painted in the most brilliant hues of Burr's eloquence. He told them that Jefferson, who was popular with them all, approved the plan. That they were to take possession of the immense grant purchased of Baron Bastrop, but that in case of a war between the United States and Spain, which might at any time occur, as the Mexicans were very weary of the Spanish yoke, Congress would send an army to protect the settlers and help Mexico, so that a new empire would be founded of a democratic type, and the settlers finding all on an equality, would be enabled to enrich themselves beyond all former precedent.

About this time rumors were circulated that Aaron Burr was plotting some mischief against the United States. Jefferson himself became alarmed, knowing as he so well did the ambition of Burr and his unprincipled character. A secret agent was sent to make inquiries in regard to the doings at Blennerhasset's Island and Marietta. This agent, Mr. John Graham, was assured by Mr. Blennerhasset that nothing was intended save the peaceful establishment of a colony on the banks of the Washita.
