No Indian, who heard us pronounce the word _Potomac_ would suspect that we meant to say the river Potum; so of _Rappa-hannah_, he would not know that we meant the river _Rappa_. So of the river _Roan_, which we call Roanoak, instead of calling it simply the river _Roan_. But enough, perhaps, too much of Indian languages. We give, however, the names correctly: Hoo, Sooske, Potum, Rappa and Roan. After spending several hours with Mr. Gallatin in his library, and after conversing with him on my business, which had brought me to the city, in which he took an interest, I returned to my lodgings in Broad street. He invited me to call on him again, and spend some time with him, on his birth day, when he would be eighty-three years old. I next visited Mr. and Mrs. Hopkins and their daughter, who boarded with Mrs. Lentner, No. 15 Amity street, near Broadway. In this house, kept by the present occupant, Colonel Trumbull spent the last twenty years of his life. Here he lived and here he died, not long before my visit. It was in this house that Colonel Trumbull executed his splendid paintings which now adorn the rotundo in the capitol at Washington city. These paintings are seen by a great number of persons every day in the year. The Declaration of Independence, the Surrender of Cornwallis, &c. &c. will confer an unfading fame on Colonel Trumbull. MRS. LENTNER will always be remembered for her care of the painter, which so greatly contributed to preserve his useful life, until he was more than eighty-seven years old. I saw in Mrs. Lentner’s parlor a likeness of Colonel Trumbull, painted by himself, in his last years. It was said to be a very correct one. So said Mrs. Lentner. After taking dinner and supper with Mrs. Lentner and her family, I returned in the omnibus to my lodgings. If any persons could prolong human life and render it happy, Mrs. Lentner, her sister, and the domestics around her, could certainly effect that object. So it seemed to me during the six hours that I spent at number 15, Amity street, New York. She is the MRS. BALLARD of New York.
