3, in the 14th concession of McNab, with the intentions of erecting mills on that lot which is now partly occupied by the flourishing village of Arnprior, would not agree to the Chief's terms, as the lot was originally a Clergy Reserve. The Chief exchanged it for another lot, drew the patent in his own name, and ejected the Rosses who, as has been before stated, went to Lower Canada and settled in Bristol. They wrote an anonymous communication to Lieut.-Governor Sir John Colborne (Baron Seaton), severely reprobating the Chief's behaviour, and animadverting in no measured terms on the conduct of the Government itself. This document was without a signature, and without either locality or date. The high-minded and honorable soldier who ruled Upper Canada, scorning such a mode of attack and complaint, at once sent the communication to the Chief. They were intimate friends. Sir John had offered McNab a place in the Government and a seat in the Legislative Council, which was politely declined. The Chief's affable manner, his imposing and noble appearance, the manly beauty of his person, and that chivalrous politeness which he had acquired in France, together with his generous expenditure, both at home and abroad, had so won on the Lieut.-Governor that he could not believe the accomplished gentleman was a tyrant, nor the handsome Highland Chieftain a cruel despot, as represented in the letter, and if one statement appeared false, the whole must be without foundation--thus reasoned the simple and honorable soldier. Besides, the complaint was anonymous and consequently cowardly and untrue. It was attributed to ingratitude and discontent. When the Laird of McNab received the communication, he was surprised at its audacity. To discover its author was his first object, to punish him his next effort. Being without a name it did not come within the category of privileged communication, and consequently the author in those days was liable to punishment. He, on the impulse of the moment, selected one of the settlers as the author--one Alexander McNab, who had been a teacher in Scotland, and who had specially emigrated to Canada to follow his profession. As such he received the location ticket for 200 acres instead of one, as had been awarded to other settlers. He was now the only educated man among the settlers. He had shown symptoms of insubordination some time previously. His handwriting was very like that of the libellous communication. He resided within two miles of Kennell Lodge, near the present Flat Rapid Road. His place is now occupied by his son-in-law, Mr. John Yuill. He received a peremptory summons to attend upon the Laird. At once obeying the mandate of his Chief, he appeared before him anxious and apprehensive. The missive he received was couched in these terms--not by any means calculated to remove his apprehension:-- KENNELL LODGE, 13th March, 1829. ALEXANDER McNAB:
