[Letter from John H. Stone to J. D. Giddings - January 27, 1872]

Description: Letter from John H. Stone to J. D. Giddings. Stone says that he is willing to sell the boarding house property to the highest bidder and have Mrs. Carmer take her share. Otherwise, a civil suit would harm everyone involved.As for Mrs. Carmer's interest, it would be best for her to sell it on the market. Stone is also frustrated that so little stock has been paid, and he seeks Giddings' advice on that matter. Stone has talked to Dr. Connor, and the latter is willing to pay the rent as soon as he knows Mrs. Carmer's prorate share.
