INTliODUCTJO^ TO VOLUME 111 



VOLUME III. contains the titles of publications relating to arboriculture and to the economic 

 properties and uses of woody plants, ijicluding important articles in periodicals and other 

 serial publications. For this volume the principal botanical, horticultural, agricultural and 

 pharmaceutical periodicals have been completely excerpted and many papers have been extracted 

 from less important technical periodicals and from those of a general character. 



It has been unpossible to attempt withhi the limits of this Bibliography a complete enumeration 

 of all publications devoted to pomology and the cultivation of fruit trees, and only separate works 

 on these subjects are included. Following the plan adopted in the dendrological part of the Biblirj- 

 graphy contained in the first two volumes, all publications dealing with a certain family, genus or 

 species are entered under their respective divisions in the taxonomic arrangement. Thus a paper 

 dealing with camphor derived from Blumea will be found under Blumea and not under Camphor, 

 and an article on the pruning of Spiraea will be found under Spiraea and not under Pruning. 



In the taxonomic arrangement the nomenclature and the sequence of families, genera and species 

 are the same as in volume ii. Additional publications dealing with the cultivation of plants and 

 their economic products in certain families, genera and species may be found in the taxonomic 

 part of volume ii.; and in volume i. are found additional references to general descriptive botany, 

 to morphology, anatomy, physiology, ecology, evolution, etc. Additional publications relating to 

 the cultivation of timber trees, their diseases and some of their economic products, particularly 

 wood, are found in volume iv. 



To the list of libraries which have been examined in the preparation of this work which ap- 

 pears in the introduction to volume i. should now be added the Boston Medical Library and the 

 Library of the Massachusetts College of Pharmacy. For valuable notes and additions to the enu- 

 meration of pomological publications the Arboretum is indebted to j\Ir. Edward A. Bunj-ard of 

 Allington, England.
