Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Excerpt from Insects Affecting Park and Woodland Trees This work was begun a number of years ago by the writer studying various insects depredating on shade trees, and from that it was very natural to give attention to those affecting forest trees. It assembles in one volume the results Of our studies for a series Of years, together with a summary Of the more important literature relating to the subject. It is not expected that this memoir will supersede the exceedingly valuable work by Dr Packard on Forest and S/um'e Tree Insects, sth Report Of the United States Entomological Commission, but rather that it will be supplementary thereto. It is hoped that the arrangement adopted will facilitate the identi fication Of the different species and aid materially in making the information accessible to the general public. The writer at this time wishes to acknowl edge his indebtedness to the assistants who have been associated with him during the past six years, all of whom have aided more or less in the preparation Of this work. Particular mention should be made Of the work of Mr D. B. Young, now assistant entomologist, who during the last three years, by collecting and otherwise, has secured much valuable data which has been incorporated in this work. Through the courtesy Of Dr L. 0. Howard, Chief of the Bureau Of Entomology, United States Department Of Agriculture, a number Of species were kindly determined by Drs Hop kins and Ashmead. The former named most Of the bark borers or Scoly tids and also generously gave the writer the benefit Of his extended experience in the study Of forest insects. Dr Ashmead is responsible for the determination Of most-of the parasitic Hymenoptera, a group in which he is a well recognized authority. The value Of the work is also greatly enhanced by the large series Of original drawings by Mr L. H. Joutel Of New York.
