Since the foregoing was written, i^r.» Rehder brought to rrgr attention the 
fact that the first Smithsonian expedition bringing back anything of scien- 
tific interest from Tahiti was that of our former Secretary, S. Pierpont 
Langley in 1901 . He returned from an informal, five weeks recreational 
trip to the Society Islands with one of the pumice-like stones from a fire- 
walker’s pit. Notes from his diary were published in the National Geographic 
Magazine for December the same year, and a more detailed account of the 
” fire-walk” ceremony x\^hich he was fortunate in witnessing formed part of the 
Appendix to the Smithsonian Annual Report for 1901 ( 1902 ; pp# 539“544« )
