Now the first odd thing about Joseph Curwen was that he did not seem to grow much older than he had been on his arrival. He engaged in shipping enterprises, purchased wharfage near Mile-End Cove, helped rebuild the Great Bridge in 1713, and in 1723 was one of the founders of the Congregational Church on the hill; but always did he retain the nondescript aspect of a man not greatly over thirty or thirty-five. As the decades mounted up, this singular quality began to excite wide notice; but Curwen always explained it by saying that he came of hardy forefathers, and practiced a simplicity of living which did not wear him out. How such simplicity could be reconciled with the inexplicable comings and goings of the secretive merchant, and with the queer gleamings of his windows at all hours of night, was not very clear to the townsfolk; and they were prone to assign other reasons for his continued youth and longevity. It was held, for the most part, that Curwen’s incessant mixings and boilings of chemicals had much to do with his condition. At length, when over fifty years had passed since the stranger’s advent, and without producing more than five years’ apparent change in his face and physique, the people began to whisper more darkly; and to meet more than halfway that desire for isolation which he had always shown.
