James Madison actually said...

"the land warrants of the said Canadian volunteers may be located agreeably to the said act at the land offices at Vincennes or Jeffersonville, in the Indiana Territory, on the first Monday in June nex..."

"should any of the warrants not appear for location on that day they may be located afterwards, according to their priority of presentation"

"the locations of the land warrants of the said volunteers should 'be subject to such regulations as to priority of choice and manner of location as the President of the United States shall direct'"

"the warrantees may, in person or by their attorneys or other legal representatives, in the presence of the register and receiver of the said land district, draw lots for the priority of location"
