On the formation of Allegheny County, Pittsburgh became the county seat. The county was divided into townships, Pittsburgh being located in Pitt Township. Embraced in Pitt Township was all the territory between the Monongahela and Allegheny Rivers, as far east as Turtle Creek on the Monongahela River, and Plum Creek on the Allegheny River, and all of the county north of the Allegheny and Ohio Rivers. With the growth of prosperity in the county, petty offenses became more numerous, and a movement was begun for the erection of a jail in Pittsburgh.[31] Next to the establishment of the _Pittsburgh Gazette_, the publication and sale of books, and the opening of the post route to the eastern country, the most important event in the early social advancement of Pittsburgh was the passage of an Act by the General Assembly, on April 22, 1794, incorporating the place into a borough. The township laws under which Pittsburgh had been administered were crude and intended only for agricultural and wild lands, and were inapplicable to the development of a town. Under the code of laws which it now obtained, it possessed functions suitable to the character which it assumed, and could perform acts leading to its material and social progress. It was given the power to open streets, to regulate and keep streets in order, to conduct markets, to abate nuisances, and to levy taxes.[32] Before the incorporation of the borough, various steps had been taken in anticipation of that event. The Pittsburgh Fire Company was organized in 1793, with an engine house[33] and a hand engine brought from Philadelphia. A new era in transportation was inaugurated on Monday, October 21, 1793, by the establishment of a packet line on the Ohio River, between Pittsburgh and Cincinnati, with boats “sailing” bi-weekly. The safety of the passengers from attacks by hostile Indians infesting the Ohio Valley, was assured. The boats were bullet-proof, and were armed with small cannon carrying pound balls; muskets and ammunition were provided, and from convenient portholes, passengers and crew could fire on the enemy.[34] One of the first measures enacted after Pittsburgh was incorporated, was that to prohibit hogs running at large.[35] The dissatisfaction occasioned by the imposition of the excise on whisky, had caused a spirit of lawlessness to spring up in the country about Pittsburgh. When this element appeared in the town, they were disposed, particularly when inflamed with whisky, to show their resentment toward the inhabitants, whom they regarded as being unfriendly to the Insurgent cause, by galloping armed through the streets, firing their pieces as they sped by, to the terror of the townspeople. This was now made an offense punishable by a fine of five shillings.[36]
