FINAL ACT OF SECOND PAN AMERICAN SCIENTIFIC CONGRESS. 27 



ARTICLE 2. 



The Second Pan American Scientific Congress requests 



The Government of the United States to bring to the attention of the 

 Governments of the American Republics participating in the 

 Congress and, through their respective Governments, to the 

 institutions and the public thereof, the importance of pro- 

 moting research in the field of archaeology, organized sur- 

 veys for the study of primitive tribes, and the building of 

 national educational museums for the preservation of the 

 data and materials collected. 



ARTICLE 3. 



The Second Pan American Scientific Congress recommends that the 

 American Republics undertake as soon as practicable 



(a) Accurate geodetic measurements which may serve to determine 

 limits, national and international, and to contribute to the 

 discovery of the true shape of our planet; 



(6) Magnetic measurements of their respective areas, and the estab- 

 lishment of several permanent magnetic observatories in 

 which it may be possible to carry on during long periods of 

 time observations concerning the secular variation of the 

 magnetic elements of the earth; 



(c) To extend their gravimetric measures, obtained by means of 

 the pendulum, to those regions where such measurements 

 have not been undertaken, in order to obtain more informa- 

 tion to determine the true shape of the surface and the dis- 

 tribution of the terrestrial mass. 



ARTICLE 4. 



The Second Pan American Scientific Congress recommends that 



The Nations of the American Continent establish, by means of their 

 ofiices of geodesy or by committees appointed for that pur- 

 pose, an international triangulation; 



The Governments of the American Nations reach an agreement for 

 the purpose of creating an office or congress of cartography 

 and geography.
