APPENDICES. 



[The foilowing appendices include such letters and reports as contain matter 

 deemed worthy of being preserved and not fully used in the body of the work. Many 

 of the reports of agents were received in the form of continued correspondence and 

 have been utilized and quoted from in the different chapters. Others again have 

 not been of such value as to warrant publication. Some of the replies to Circular 

 No. 7 (see Introduction) are added in Appendix VIII, the replies being numbered to 

 correspond to the questions. The reports as well as the answers to the circular are 

 printed just as they were received and without comment, though it is hardly necessary 

 to inform the reader who has perused the different chapters that the views and theories 

 of the different writers are not necessarily indorsed. They are, rather, published to 

 illustrate the conflicting views and theories held by the more intelligent correspond-
