United States Marshal's Office--Complaint was made against J. Carlton Comstock and Geo. Wells Comstock, of No. 9 John Street, and a clerk in their employ, for taking letters from the Post Office, belonging to Dr. L.S. Comstock, of 57 in the same street. Dr. Comstock having missed a large number of letters, on inquiry at the Post Office it was suspected that they had been taken to No. 9 John Street. By an arrangement with the Postmaster and his assistants, several letters were then put in the Post Office, containing orders addressed to Dr. Comstock, at 57 John Street, for goods to be sent to various places in the city to be forwarded to the country. The letters were taken by the accused or their clerk, opened at No. 9, the money taken out and the articles sent as directed, accompanied by bills in the handwriting of Geo. Wells Comstock. Warrants were then issued by the U.S. Commissioner and Recorder Talmadge, and two of the accused found at home were arrested and a large number of letters belonging to Dr. C. found on the premises. J.C. Comstock has not yet been arrested. It is said he is out of the city. These two young men have for some months been trading sometimes under the name of "Comstock & Brother", and sometimes as "Judson & Co." at No. 9 John Street. The same episode was also mentioned in the _Express_, the _Commercial Advertiser_, and the _Tribune_. In fact, a spirited debate in the "affair of the letters" was carried on in the pages of the press for a week. The brothers defended themselves in the following notice printed in the _Morning Express_ for May 31: OBTAINING LETTERS Painful as it is, we are again compelled to appear before the public in defense of our character as citizens and business men. The two letters referred to by L.S. Comstock (one of which contained One Dollar only) _were both directed "Comstock & Co." which letters we claim; and we repeat what we have before said, and what we shall prove that no letter or letters from any source directed to L.S. Comstock or Lucius S. Comstock have been taken or obtained by either of us or any one in our employ_. The public can judge whether a sense of "duty to the Post Office Department and the community", induced our brother to make this charge against us (which if proved would consign us to the Penitentiary) and under the pretence of searching for letters, which perhaps never existed; to send Police Officers to invade not only our store, but our dwelling house, where not even the presence of our aged Mother could protect from intrusion. These are the means by which he has put himself [Footnote 3: Receipts for these registrations were signed by the prominent librarian, Charles Coffin Jewett, later to be superintendent of the Boston Public Library for many years.]
