In a memoir lately communicated to the Society by governor Pownall on the origin and nature of picture and elementary writing he observes that he has heard of painting on trees by the Indians in North America, but that he never saw any of them.Recollecting that a gentleman of my acquaintance had shewed me in his journal a copy of an historical painting in figures which he had taken from a tree in North America, I wrote to him, and have been favored with the annexed sketch and interpretation of it.
