1820  (1939)  I hope Mr. Williams will not be deterred from following up the plan I suggested of a flying post about Lac Winipec either on land or water.
1867  (1913)  Fort Ellice had a regular winter outpost at Riding Montain, besides flying posts wherever the buffalo were numerous, at such places as Turtle and Moose Mountain.
1921  Meanwhile, canoes laden with furs and in charge of Hudson's Bay traders or clerks from outlying "Flying Posts" had arrived.
