Another of the most important features of this year, perhaps indeed the very most important, was one which will now produce a smile. At that time, however, it was a subject of serious congratulation to the inhabitants of the new country. This was no less than the large immigration of young unmarried women into this region, abounding in young unmarried men. One of the historians of the time, in chronicling this event, remarks, with all the soberness and propriety due to the most solemn subject, that "the necessary consequence of this large influx of girls was the rapid and wonderful increase of population." Whether this increase was produced by purely natural means or by foreign immigration is left by him in the profoundest doubt. Perhaps that worthy individual known as "The Oldest Inhabitant" could elucidate this point. The only other circumstance worthy of notice during the year, was the building at the falls of a new fort. History gives us no information either as to the name or location of this position of defense. Its very name and history is swallowed up in that of Fort Nelson which must have been built very soon after, if it was not commenced at the same time as this nameless fort. Fort Nelson was built in 1782 by the regular troops, assisted by all the militia of the State. It was situated between Sixth and Eighth Streets on the North side of Main, immediately upon the "second bank" of the river. Its name was derived, as some say from Capt. Nelson, an influential citizen of Louisville in that day, but more probably was named in honor of the third republican governor of Virginia. It contained about an acre of ground and was surrounded by a ditch eight feet wide and ten feet deep, intersected in the middle by a sharp row of pickets. This ditch was surmounted by a breast work of log pens filled with the earth obtained from the ditch, with pickets ten feet high planted on the top of the breast work. Next to the river, pickets were deemed sufficient, aided by the long slope of the bank. There was artillery likewise in the fort. Col. Slaughter had brought with him several very small cannon, and Gen. Clark had placed here a double fortified six-pounder, which he had captured at Vincennes. This last piece played no inconsiderable part both in the previous and subsequent expeditions of this General. The present site of Seventh Street passed directly through the gate of the fort opposite the head quarters of Gen. Clark. The pickets and various other parts of this fort have been from time to time, since 1830, dug up in excavating cellars at the place formerly occupied by the post. Many of the pickets thus excavated have been made into walking canes and are valued as memorials of the past.
