FOREWORD. 



have gone to much trouble and pains to promote my work. 

 Two Secretaries of State, one Secretary of the Interior and 

 several scientific men of the Department of Agriculture 

 have, by their kindly help, demonstrated the public spirit 

 of our high officers. It is difficult for a reader of this book 

 to appreciate what this help has been. Sometimes two or 

 three words in a line will represent voluminous and pro- 

 longed correspondence. Sometimes the result of a year's 

 investigation is to leave some statement out entirely. 



This work is arranged in two divisions. The first con- 

 tains a popular account of the species of Eucalyptus intro- 

 duced into California as far as known. The location of 

 illustrative specimens is in each case indicated so that en- 

 quirers may readily see for themselves what the tree looks 

 like. The second division will contain the special exam- 

 ination of points of interest in this genus including 

 methods of planting, timber strength, the oils and kinos, 

 the medicinal value, the sanitary influence, vernacular 

 names and lists of species suited to different conditions of 

 soil and climate. This division will also contain a con- 

 densed botanic description of all the species of Eucalyptus 

 described by Baron Von Mueller and taken from his great 

 work. A few notes regarding varieties and points noted 

 in California will be added to this. To facilitate the use 

 of these botanic descriptions there will be a key and an 

 illustration of the typical anthers, magnified sixty times, 

 prepared by Prof. McClatchie, of the four classes estab- 

 lished by Von Mueller. I believe that the ke} T , plate and 

 descriptions will enable any intelligent person to identify 

 the leading species of Eucalyptus. To complete this part 

 of the plan there will be a botanic glossary.
