He was soaked in Scripture, especially in the Old Testament, a soaking which has somewhat the same effect on the moral and mental fibre that seven years in a tanner's vat used to have upon sole leather. How often I have known Adin, on some great political occasion or crisis, to crush some sophistry or compromise, or attempt to get things on a lower plane, by indignantly flashing out with some old text, such as, "Righteousness exalteth a nation," or "Sin is a reproach to any people," or answer, as he did once, to a gentleman who wanted him to sacrifice some moral principle for the sake of harmony in the Republican Party, "My friend, we will be first pure, and then peaceable." Adin Thayer was a member of the School Committee of Worcester for some years. He was Senator from Worcester, I think, for two years, in 1871 and 1872. He was appointed Collector of Internal Revenue for the eighth district by President Lincoln on August 26, 1862, and gave way to a successor appointed by President Johnson, September 14, 1866. He was reappointed by President Grant, June 22, 1872, and held the office until January, 1877, when the eighth and tenth districts were consolidated. He was appointed Judge of Probate by Governor Rice in the fall of 1877, and held that office until his death. He was Chairman of the State Committee in 1878. He gave to the public three or four essays or speeches printed in newspapers, and some of them in pamphlet form. They were, under one title or another, treatises on the moral duties of citizenship and appeals to the youth of the State to take their full and patriotic share in its administration.
