Dr Bomierjea was especially appreciative of the interest, sugges- 

 tions, and advice of Dr. Matthew W. Stirling, then chief of the Bu- 

 reau, Dr. John R. Swanton, and Dr. Truman Michelson. He also 

 indicated that he was fully aware of imperfections m his work, but 

 ventured the hope that it would be useful to people seachmg through 

 the maze of otherwise hard-to-find information contained m the 



volmnes. ^
