Captain Welcome Lothrop succeeded Mr. Butler as postmaster, and during his administration the office was kept in Liberty Hall.  Captain Lothrop was a native of Easton, Massachusetts, and a land-surveyor of some repute in this neighborhood.  Artemas Wood followed him by appointment on February 22, 1849; but he never entered upon the duties of his office.  He was succeeded by George H. Brown, who had published The Spirit of the Times—­a political newspaper—­during the presidential canvass of 1848, and in this way had become somewhat prominent as a local politician.  Mr. Brown was appointed on May 4, 1849; and during his term the office was kept in an ell of his dwelling-house, which was situated nearly opposite to the Orthodox meeting-house.  He was afterward the postmaster of Ayer.  Mr. Brown was followed by Theodore Andruss, a native of Orford, New Hampshire, who was commissioned on April 11, 1853.  Mr. Andruss brought the office back to Liberty Hall, and continued to be the incumbent until April 22, 1861, when he was succeeded by George W. Fiske.  On February 13, 1867, Henry Woodcock was appointed to the position, and the office was then removed to the Town Hall, where most excellent accommodations were given to the public.

He was followed on June 11, 1869, by Miss Harriet E. Farnsworth, now Mrs. Marion Putnam; and she in turn was succeeded on July 2, 1880, by Mrs. Christina D. (Caryl) Fosdick, the widow of Samuel Woodbury Fosdick, and the present incumbent.

The office is still kept in the Town Hall, and there is no reason to think that it will be removed from the spacious and commodious quarters it now occupies, for a long time to come.  Few towns in the Commonwealth can present such an array of distinguished men among their postmasters as those of Groton, including, as it does, the names of Judge Dana, Judge Richardson, Mr. Butler, and Governor Boutwell.

By the new postal law which went into operation on the first of last October, the postage is now two cents to any part of the United States, on all letters not exceeding half an ounce in weight.  This rate certainly seems cheap enough, but in time the public will demand the same service for a cent.  Less than forty years ago the charge was five cents for any distance not exceeding three hundred miles, and ten cents for any greater distance.  This was the rate established by the law which took effect on July 1, 1845; and it was not changed until July, 1851, when it was reduced to three cents on single letters, prepaid, or five cents, if not prepaid, for all distances under three thousand miles.  By the law which went into operation on June 30, 1863, prepayment by stamps was made compulsory, the rate remaining at three cents; though a special clause was inserted, by which the letters of soldiers or sailors, then fighting for the Union in the army or navy, might go without prepayment.
