The World's Commercial Products 



would have any interest all vegetable commercial products. To do this the work would have 

 to run to. many, volumes. Thus, some years ago, the Government of India produced, under 

 the direction of Sir George Watt; a Dictionary of the Economic Products of India. Now, 

 India, although a large country, is small in comparison with the whole world, and yet this work 

 on Indian products alone* extends to a monumental series of eight large-paged volumes. A 

 selection has, therefore, had to -fee- made, and, for purposes of convenience, the products have 

 been arranged in natural gr.oups. This method has allowed of general information being given 

 on properties common to all the members of the group, of devoting most space to the more import- 

 ant products, and of mentioning the others in their appropriate places without that detachment 

 often. entailed-in a book in which each product is treated of separately without reference to 

 its place in a great group. 



The. results of personal observations in many parts of the world, contributions from experts 

 engaged daily in handling the products under consideration, and the consultation of standard 

 authorities have been blended to make the volume as far as practicable a concise and simple 

 account of '.the chief plant products of the world. The book cannot hope to be faultless and the 

 magnitude and complexity of the subject treated must be our excuse for any shortcomings.
