A GEOLOGIC FORECAST OF THE FUTURE 

 OPPORTUNITIES OF OUR RACE' 



To those organizations that are strug- 

 gling with the presidential problem, from 

 Central American republics to social clubs, 

 one may cordially recommend the unique 

 practise of this association, for the adroit- 

 ness with which it makes the presidential 

 office go twice as far as is usual, while at 

 the same time it reduces the hazard of the 

 association to the lowest terms. Near the 

 close of an annual session a president is 

 chosen and is at once permitted to enter 

 upon the annual functions of the office by 

 attaching his signature to certificates of 

 membership, which it is assumed he is 

 competent at once to do, but he does not 

 enter upon any conspicuous or presenta- 

 tive functions so unpreparedly; the retir- 

 ing president holds the stage for the suc- 

 ceeding year. At the next annual session, 

 after a year of manual practise exercised 

 on relays of certificates that come at close 

 intervals, the incoming president is form- 

 ally introduced to the association and as- 

 sumes the chair. During this session he 

 responds to addresses of welcome and pre- 

 sides over the general sessions of the as- 

 sociation with as much grace and dignity 

 as he may be able to command, but beyond 

 this he has no specific occasion, nor does 

 the association assume any responsibility, 

 for anything that might betray scientific 

 attainments or the possession of opinions. 

 Near the close of the session, a new presi- 

 dent is chosen, and the active president 

 enters upon his career as retiring presi-
