In March, 1877, desiring a more extensive field of business operation, Mr. Carpenter resigned his position as cashier of the Pittsfield National Bank and removed to the city of Manchester, where, with characteristic vigor and enterprise, he immediately set about the work of procuring a charter for and organizing the Second National Bank of Manchester, of which institution he has been a director and cashier since its organization. The national bank being well established, he assisted in securing a charter for and organizing the Mechanics Savings Bank, of which he has been from the first a trustee and the treasurer. Both these institutions, under his skillful supervision, have attained a prosperous and flourishing condition. Aside from his general banking operations, he has in Manchester, as elsewhere, dealt extensively in notes, bonds, and real estate, and has been, for the past few years, quite largely engaged in building. In company with ex-Gov. Smyth, he is proprietor of Smyth and Carpenter's block, on Elm street, the northern half of which has recently been completed. This block is four stories high and basement; has a frontage, on Elm street, of two hundred feet, a depth of one hundred feet; contains ten stores on the first floor, with offices and tenements above; and is, beyond question, the largest brick block in the state in the ownership of any single firm. Mr. Carpenter has always manifested an interest in educational affairs, and has been specially interested in the establishment and prosperity of the Holderness School for Boys, located at Holderness in this state, under the auspices of the Episcopalian denomination, with which he is associated. He has been one of the trustees of this school from the inception of the enterprise, and is also the treasurer. He devoted much time and personal care to the work of remodeling the buildings at the outset, and, since then, to their enlargement as the growth and success of the school has demanded.
