We know but one example of his book-plate work, and that is the _Lenthall_ plate, which is a large and very interesting example of the Ribbon and Wreath style. It is an excellent piece of engraving, full of style, and graceful in design. * * * * * JAMES TRENCHARD was born in Cumberland County, New Jersey, about 1746. He was a pupil of Smithers, and engraved in Philadelphia, [Illustration: JOHN LENTHALL] about 1785. Among his pupils were Thackara, Vallance, and his nephew, Edward Trenchard, who became an officer in the United States Navy, and served in the War of 1812. Trenchard was one of the owners of the “Columbian Magazine,” published in Philadelphia from 1786 to 1792, and he engraved many plates for its pages. [Illustration: Bloomfield] One signed book-plate of his is known,--the _Bloomfield_. This is a Chippendale plate of no striking features. The _Luther Martin_ plate is so similar to this as to leave hardly any doubt that it too was by Trenchard. * * * * * [Illustration: Luther Martin A M] JAMES TURNER is another of the early American artists of whom very little is known now. He was at one time in Boston, but later removed to Philadelphia. He did some portrait and some music work. Of his book-plate work we have but three signed specimens. By far the most interesting and valuable of these is the extremely rare plate of _John Franklin of Boston in New England_. This is very fully described in the List of Early American Book-plates. The other plates are the _Sir John St. Clair_, and the plate for _Isaac Norris_, of the family of the Quaker Chief Justice of Pennsylvania. [Illustration: John Franklin Boston New England] The plate of _James Hall_, although not signed, is also attributed to him. * * * * * JOHN VALLANCE, whose name is connected with that of Thackara, engraved with him many plates for Dobson’s Encyclopædia. He made heads of Franklin and Howard, which were pronounced successful, and he had a high reputation as an engraver. [Illustration: Bloomfield Maine.] One authenticated example of his book-plate work is known, the _Joseph Wiseman_, in the Ribbon and Wreath style; and the _David Brearly_, although not signed, is attributed to him. * * * * * Of the other engravers whose names appear on but one or two plates, no information has been obtained. There were probably many who had but a local fame, and who made but a few plates. Their names are remembered now in a way not expected at the time of signing them, undoubtedly. * * * * * In a recent article on COUNT RUMFORD, in the “New England Magazine,” it is said that, when a youth, he designed book-plates. No authentic examples of his work are known, and no information can be obtained concerning any. * * * * *
