By the kindness of Mr. W. R. Smith, of the United States Botanic Garden, and of Miss Mumford, of Washington, the Editor some time since came into possession of a set of magazines very much in the style of Flowers and Ferns, of the United States, which, under the name of American Botanical Register, was issued at Washington. There is no editor's name nor any date; but we find from outside investigation that it was issued in Washington in 1831, and that the editors were Drs. Rich and Brereton. On one page of a fly-leaf, which has been preserved, it appears that the flowers were engraved by W. S. Pendleton, and then colored by hand.

The art of chromo lithography has been of so much value to horticulture that in the belief that Pendleton was in some way instrumental in introducing the art, it occurred to us that it would be interesting to have the history of the art developed for our readers. We have the following letter from Mr. S. R. Koehler, of Roxbury, Mass., which we give in the hope that it will bring out further information in regard to the history of this very useful art:

"So far as I have been able to learn up to the present, the first specimen of work on stone in America was done by Bass Otis, of Philadelphia, and published in 1818. This, however, a little landscape, was engraved on stone, not drawn with lithographic crayon, and no one would suspect it to be from stone without previously knowing it.

"Barnett & Doolittle had a lithographic press in New York in 1822; but I have only seen some diagrams done by them, which may be pen-and-ink work.

"J. Pendleton (the brother of W. S., who seems to have been only a publisher) announced in November, 1825, in Boston, that he had studied the art in Europe, and introduced it, and in February, 1826, formed a copartnership with his brother (W. S.), who had previously been in partnership with Abel Bowen, an engraver. Abel Bowen also took up lithography, and some of the earliest work done in Boston and published in 1825 bears his name. So far as I know, Pendleton was a born American, and went to Europe to study lithography.

" I cannot tell you when chromo-lithography was first practiced in the United States. Some of the earliest work really worthy of that name was certainly done by William Sharp, an Englishman, who came to Boston about 1848.

"I have for some years been trying to work up the history of lithography in the United States, but it is very difficult to get reliable information".
