Collins–Valentine line

The Collins–Valentine line, or Valentine–Collins line, is the boundary at approximately 45 degrees north latitude that separates the province of Quebec from the states of New York and Vermont. It was surveyed and marked by survey monuments in 1771–3 by John Collins, surveyor-general of Quebec, and Thomas Valentine, a commissioner appointed by the government of New York. The Treaty of Paris of 1783, which established peace between Britain and the United States, said the boundary was to be the 45th parallel, and it was generally assumed that that is where the line marked by monuments is.
