This arrangement left St. John unprovided with connection with either Quebec or Halifax, but it was brought into the scheme by a separate courier who met the couriers on the main route at Sussexvale. The travel on the new route was at first very bad, but the lieutenant governors of the two Maritime provinces, who were interested in the success of the scheme, promised to do their best to induce their assemblies to put the roads in good condition.
In changing the route from Fredericton to Halifax, and requiring the couriers to travel inland, instead of along the waterways, the deputy postmaster general was taking a measure in the direction of safety, but those who had a particular interest in the transmission of their correspondence intact could not look without concern at the exposure of the mails on the long stretch between the foot of lake Temiscouata and Fredericton.
The lieutenant governor of Nova Scotia and the admiral of the Halifax station were both uneasy at the possibility of their despatches being intercepted by the Americans, and grasped eagerly at a suggestion thrown out that the courier from Halifax should not go to Fredericton at all, but on leaving Amherst should pursue a north-westerly course till he reached the Matapedia river at the western end of the bay of Chaleurs. From this point, the route would lie across the bottom of the Gaspe peninsula to the St. Lawrence near Metis.
The suggested route encountered the strong opposition of Heriot.[164] "The heights of the interior," he declared, "are more elevated than those towards the sea, and some of them with snow on their summits which remain undissolved from one year to the other. The land between the mountains is probably intersected by rugged defiles, by swamps and by deep and impracticable gullies. A region so inhospitable and desolate as from its interior aspect, and its latitude as this may without exaggeration be conceived to be, can scarcely be visited by savages. Suppose a road were cut through this rugged desert, it would not be possible to find any person who would settle there, and no courier could proceed on foot for a journey of some hundred miles, through a difficult and dreary waste alike destitute of shelter and of the prospect of assistance."
Heriot's conviction was that the present route was the only possible one, and if the enemy threatened to cut off communications, it might be necessary to establish two additional military posts, one at the head of the Madawaska settlement, the other between Grand Falls and Presqu' Isle.
A blockhouse at each point, with a non-commissioned officer, a few privates and two savages attached, would in Heriot's opinion afford sufficient protection. The enemy would scarcely incur the trouble and expense of marching one or two hundred men from an immense distance to take or destroy these forts with the precarious and doubtful prospect of interrupting a courier, to whom the nature of the country presented a variety of means of eluding their utmost vigilance.
The idea of establishing a route between Nova Scotia and the St. Lawrence, which would follow the northern shore of New Brunswick, was not carried into effect at once, but as will be seen it occupied attention from time to time and was eventually realized.
The war affected the postal service in Lower Canada to the extent of causing the conveyance of the mails between Montreal and Quebec to be increased from twice a week to daily.[165] Sir George Prevost having pointed out to Heriot the necessity for more frequent communication on account of the war, the latter expressed his willingness to increase the trips, but stipulated that the men employed in the service should not be subject to enlistment as it was very difficult to secure trustworthy men.
The governor agreed, and directed the colonels of militia that they were to impose no military duties on post office employees. On the conclusion of the war, the couriers' trips were reduced from six to five weekly, at which frequency they remained for many years.
The last year of Heriot's administration was marked by a disagreeable quarrel with Sir Gordon Drummond,[166] who was administrator of Canada on Prevost's retirement. In the beginning of 1815, the legislature of Upper Canada adopted an address pointing out that the postal arrangements were very defective, and expressing the opinion that the revenue from Upper Canada was ample to meet the additional expense necessary to put the service on a satisfactory footing. If an efficient service were provided, and it turned out that they were wrong in their anticipation of increased revenues, they were prepared to pay higher rates of postage.
