Nor did the situation show a prospect of improvement. The United States perceived that the toll which the Canadian post office would have to pay for leave to pass over their territory might be greatly increased by the simple expedient of establishing a post office near the Canadian boundary, and compelling the Canadian post office to pay a wayleave equal to the ordinary postage for the distance between that post office and New York, as well as the courier's wages and necessary expenses, for the Americans did not propose to be at any expense in the matter. This scheme would net the Americans four shillings an ounce.

But as has happened so often since in the relations of Canada with her neighbour to the south, the Canadian post office was driven by these oppressive charges to the development of the alternative, though naturally much less favourable, opening to the sea. The distance from Quebec to Halifax by the Temiscouata route was six hundred and twenty-seven miles as against rather less than four hundred miles, which is the distance from Montreal to New York.

The route to New York was the natural highway, which for a century and more had been pursued by Indians, soldiers and travellers on their way from the British American colonies to Canada. On the journey southward from Montreal to New York, there was a good road from Laprairie, opposite Montreal to fort St. John, which was connected by the river Richelieu with lake Champlain.

The trip down the lake from fort St. John to Crown Point (or fort Frederic) was easily and pleasantly made by canoe or bateau. From Crown Point, the traveller had a choice of routes to the Hudson river, which bore him to New York. Kalm, the Swedish naturalist who visited Canada in 1749, entered the country by the route described, and his account of the trip suggests no unusual difficulties.[129]

Before the war the mail couriers from Montreal to New York made the journey in from nine to ten days. The journey to Halifax was of a very different character. At the best it could not be made in less than a month, and during a considerable period at the beginning and the end of each winter season the trip was very arduous and dangerous.

There has been preserved the journal of a courier, Durand, who carried a mail from Quebec to Halifax and back in the early winter months of 1784.[130] His trip downwards, starting on the 11th of January, offered no features unusual in a winter journey, most of which must be made on foot through a country a large part of which was unsettled. He reached Halifax on the 29th of February, seven weeks from starting.

The journey homeward was exceedingly toilsome and dangerous, and as conditions remained unchanged for many years, at this season when winter was relaxing its hold, it may be worth while to note some of the incidents on the route.

At the Bay du Portage, on the lower St. John, Durand and his three companions broke through the ice, and they with their mails were rescued with difficulty. They managed to get as far as Presqu' Isle, partly on the honeycombed ice, and partly in the woods, when they found themselves face to face with an ice jam. As it was impossible for Durand to land his dogs on the shore, he clambered up the hill of ice, and he and the dogs had to make their way as best they could over the broken heaped-up pieces for twenty miles, when they came upon a stretch of water as clear as in summer.

Durand's guide had abandoned him and taken to the woods, but finding the snow too soft for his snow-shoes, after a league's trudging, he rejoined Durand on the ice. The swift and swollen waters, which they now reached, compelled them to wait till they could build a canoe. Embarking they poled their way for a couple of miles, as the speed of the current prevented rowing, when the ice began again to come down upon them in great masses.

Harnessing their dogs to an Indian cart, they hauled their canoe another stretch, and on the 14th of April they reached Grand Falls. Above the falls the ice, though bad, was firm enough; and having constructed a sled, they carried their canoe and baggage on it for fifteen leagues. From this point onward, although their difficulties were by no means at an end, they struggled on to the St. Lawrence, and reached Quebec on the 24th of April.
