Five years have passed since the author very hastily penned the first edition of his Book of Flowers. The work was originally designed to be embraced in two hundred pages; but it was found impossible to treat of all the plants which were to be brought to notice, with even a brief description of their habits, modes of culture, etc., in so limited a space. It was, therefore, extended to three hundred and thirty-six pages. But, with this extension, many things were necessarily omitted, to make the work complete. One great omission was, a chapter on the cultivation of plants in the parlor, of which the author has very often been reminded by female amateurs from every part of the country. In this edition the ladies will find the desired instruction; for which, if they are more successful in consequence of the hints thrown out, the author will feel himself amply rewarded.

Many new and beautiful plants for the flower-garden have been introduced since this work was written, and many old standard varieties have been so much improved, that those formerly highly prized are now thrown aside and rejected.

I shall give a brief notice of those that may be thought desirable fur open culture. Some trees and plants, that were hopefully spoken of as probably enduring this northern climate, and have not succeeded, will be noted.

The author feels under great obligations for the favorable notices which have been given of this work by the public press, and particularly to numerous individuals from every part of the country, who, in their private communications, have spoken of it in high terms, as being a work very much needed, and as meeting the wants of young amateurs.
