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 The Fungal Diseases of the Common Larch This book arose from an investigation which Sir William Schlich asked me to make into the larch canker, a disease on which many articles and papers have been published, though no full and connected account of it has ever been written in English. While studying the canker in the field, I very frequently encountered certain other diseases on the larch, especially the heart-rot and the honey fungus, and it seemed better to include these in the scope of the investigation. For the sake of completeness, all the known diseases on the common larch have also been described, and it is hoped that a book of more general usefulness has been thereby produced. Certain fungi, such as Lophodermium laricis and Botrytis cinerea, which have occasionally been reported as parasitic on the larch, have been omitted, as no reliable evidence of their causing disease has been forthcoming. The arrangement of the diseases bears no relation to the systematic position of the fungi. They are mostly given in the order in which they were studied, which approximates closely to the order of their importance. The work was made possible by a grant from the Development Commissioners, received through the Board of Agriculture and Fisheries, and latterly through the Interim Forest Authority. Especial acknowledgement is due to these departments, particularly to the last named, which has assisted me in a variety of ways. I also desire to thank Sir William Schlich for constant help and encouragement, and Messrs. A. W. Borthwick and Malcolm Wilson for permission to reproduce Fig.72 from the Transactions of the Royal Scottish Arboricultural Society.

Urban trees on the prairies are essential to our changing landscape environment. I have helped thousands of people with their tree problems over the past 43 years. Tree diseases and how to deal with them continue to plague a very large number of people. "Where can we get more information about these tree problems?" is a question I am constantly being asked. This book will help you to narrow the search for the problems plaguing your trees by going through the images and accompanied text. As well, there are also helpful detailed instructions on how to take care of the nutritional requirements of your trees. Keeping a tree healthy can reduce its susceptibility to diseases much as good nutrition does with people and animals. You can always reach me on line at www.treeexperts.mb.ca if you need any further help. Enjoy your trees!
