He left his family in Tunbridge, on his farm, and while he was engaged in business at Detroit he visited them--sometimes once in a year, in eighteen months, or in two years, just as it happened. I visited Detroit, November 1, 1820, where I found the Major merchandising upon quite an extensive scale, having six clerks in one store; besides this, he had many other stores in the territory of Michigan, as well as in various parts of Ohio. His business at Pontiac was principally farming and building, but in order to facilitate these two branches of business, he set in operation a saw and flour mill, and afterwards added different branches of mechanism. He made the turnpike road from Detroit to Pontiac at his own expense. He also did considerable other public work, for the purpose of giving employment to the poor. He never encouraged idleness, or the man above his business. In 1828, having been absent from Detroit a short time, I returned. The Major was then a member of the Council of the territory, and had acted a very conspicuous part in enhancing its prosperity and enlarging its settlement; and it was a common saying, that he had done much more for the territory than any other individual. In short, the Major was a man of talents of the first order. He was energetic and untiring. He always encouraged industry, and was very cautious how he applied his acts of charity. Respectfully by Horace Stanly. My brother was in the city of Detroit in 1812, the year in which Hull surrendered the territory to the British crown. My brother being somewhat celebrated for his prowess, was selected by General Hull to take the command of a company, as captain. After a short service in this office, he was ordered to surrender. At this his indignation was roused to the highest pitch. He broke his sword across his knee, and throwing it into the lake, exclaimed that he would never submit to such a disgraceful compromise while the blood of an American continued to run through his veins. This drew the especial vengeance of the army upon his head; and his property, doubtless, would have been sacrificed to their resentment, had they known the situation of his affairs. But this they did not know, as his housekeeper deceived them by a stratagem, related by Mr. Stanly, as follows: At the surrender of Detroit, not having as yet moved his family hither, Major Mack had an elderly lady, by the name of Trotwine, keeping house for him. The old lady took in some of the most distinguished British officers as boarders. She justified them in their course of conduct towards the Yankees, and, by her shrewdness and tact, she gained the esteem of the officers, and thus secured through them the good will of the soldiery, so far as to prevent their burning (what they supposed to be) her store and dwelling, both of which were splendid buildings.
