was on the board of commissioners which settled financial accounts between the various states and the newly established federal government. In the 1790s, Irvine played a significant role in surveying lands and laying out the boundaries of towns in western Pennsylvania. Irvine purchased several tracts of land near the mouth of Brokenstraw Creek at the Allegheny River, some of which he gave to his son Callender. The area would soon grow into and become the town of Warren, Pennsylvania. Irvine's eldest son, Callender Irvine cultivated the land, established a general store nearby, and built a fine house on a bluff which overlooked the river. The estate came to be known as "Brokenstraw" which became the home and center of business for three generations of Irvine's descendants. Callender's son, Dr. William A.

Most of their investments were made in flour and whiskey which were mostly sold in the Ohio and upper Mississippi Valleys. In the late 1790s, Irvine assumed a military role one last time, in response to another tax rebellion. During 1797, rising tensions between France and the United States led the American government to seek financing with which to improve the military and prepare for what became the Quasi-War. To fund the war Congress levied a tax on houses and other property. The new tax came to be known as the window tax, based on the size of a house as determined by the number of windows. In response, citizens rebelled in what came to be called the Fries Rebellion which primarily involved the Dutch in Pennsylvania. Some tax collectors were driven out of towns and even imprisoned. To put down the rebellion President Adams ordered troops to
