nine o'clock
On the night of the secret meeting the members arrive at the mill by various routes . There are three entrances on land and a wharf extends along the eastern limit of the enclosure . Five of the delegates cross the river in a skiff . At nine o'clock all the men are present . They gather on the second floor of the storage shed , a brick structure one hundred by one hundred and fifty feet in area , and three stories high . There are no windows in its bleak walls . On each floor in the wall that faces the interior court of the mill enclosure are two corrugated iron doors .
