Power encloses a slip of paper cut from a letter received by him in January from Patrick S. Casserly of New York. If the booksellers from the States are to forward whatever books the people may be in need of there is nothing like punctual payment to insure a continuance of this kind attention. Power will ask Mr. Casserly to write in the future directly to Lefevere if ever his interference may be judged necessary. In a postscript, Power says that in order to save postage he will send a copy of the extract from the letter in which Casserly says that in September 1841 he forwarded to Father Thomas Cullen of Ann Arbor, Michigan an invoice of books amounting to $51.25 for which he has not been paid. Being pressed by his creditors, bad times, and the support of a large family he asks the interference of the Bishop of Detroit. The extract is copied and certified by Father J J Hay. :: III-2-h A.L.S. 2pp. 8vo.
