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. Herein lay a difficulty for the postmaster general. The postal charges in Canada were the same as those in Great Britain, and were collected by the authority of the same act of parliament. The postmaster general was not free from doubts as to the legality of the proceedings of the post office in taking postage in Canada, and he did not wish to raise the question by the enactment of a special act for Canada. He intimated to Heriot his disinclination to bring the question into prominence in Canada, and asked Heriot to give his mind to the proposition for an improvement in the service. About the time the letter from the postmaster general containing this instruction reached Heriot, Drummond himself wrote to Heriot, drawing attention to the shortcomings in the service, expressing his conviction that the necessary improvements would lead to enhanced revenues, and concluding with an intimation that unless he were provided with adequate facilities for communicating with that part of his command which was in Upper Canada, he would be obliged to restore military expresses. Sir Gordon Drummond's services to Canada during the war were such as to entitle him to an honourable place in the memory of Canadians, but he did not appear at his best in his controversy with Heriot. He exhibited too much of that arbitrariness and impatience with other people's views which is commonly observed among military chiefs. Heriot replied promptly to the governor's letter, stating that he had invited tenders for a semi-weekly service between Montreal and Kingston, and that the offers he received were quite beyond any possible revenue to be derived from the service. He had, however, accelerated the existing service by having the couriers travel on horseback, the horses being changed at convenient distances along the route.
