Efforts, it is true, were made by the Pyncheons, not only then, but at various periods for nearly a hundred years afterwards, to obtain what they stubbornly persisted in deeming their right. But, in course of time, the territory was partly re-granted to more favored individuals, and partly cleared and occupied by actual settlers. These last, if they ever heard of the Pyncheon title, would have laughed at the idea of any man's asserting a right—on the strength of moldy parchments, signed with the faded autographs of governors and legislators long dead and forgotten—to the lands which they or their fathers had wrested from the wild hand of nature, by their own sturdy toil.

In the better specimens of the breed, this peculiarity threw an ideal grace over the hard material of human life, without stealing away any truly valuable quality.
