A Popular Account of the Trees in the Streets and Gardens of Salem, and of the Native Trees of Essex County, Massachusetts, With the Location of Trees, and Historical, and Botanical Notes

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. These articles upon the trees of Salem and its neighborhood were prepared for the Salem Gazette from notes made during the season of 1890, and appeared each week in the columns of that paper through the summer of 1891. They have since been revised and some additional matter introduced for publication in pamphlet form, at the request of the directors of the Essex Institute.<br><br>They were written for popular entertainment and instruction at the request of the Editors of the Gazette; and, although arranged with considerable care, they are not intended as botanical essays and the writer would not wish to have them so considered by professional botanists. For convenience of referring to the time of flowering and other conditions of the trees the date of publication is given at the close of each sketch.
