\. EXPERIMENTS IN GEOCRAPHWAL 

 DESCRIPTION ' 



THE PRESENT CONDITION OF OUR ASSOCIA- 

 TION 



The exploration of unknown lands and 

 seas has, to my regret, seldom been the 

 subject of essays presented before our as- 

 sociation. It would appear that most of 

 those who are active or bold enough to 

 make their way far from the beaten track 

 do not care for the more thorough study of 

 geography to which we are pledged; or 

 perhaps that we, with our interest in the 

 more scientific and analytical aspects of 

 geography, have not been sufficiently cor- 

 dial to those explorers who go far from 

 home and bring back narratives in which 

 personal adventure almost necessarily has 

 a large place. Nevertheless, we have not 

 been altogether wanting in this respect. 

 We have heard in earlier meetings some- 

 thing of the desert basins of inner Asia, 

 of the lofty plateaus of the Andes, and of 

 the great territory of Alaska; and I trust 

 that we shall again from time to time have 

 reports on distant parts of the world, par- 

 ticularly when they can be presented with 

 such technical geographical skill as char- 

 acterized the papers just referred to. 

 Some such papers are listed in our pro- 

 gram for this meeting, but if I thus call 

 especial attention to the recent studious 

 travels of Messrs. "Woodworth, Huntington 

 and Martin, it would be unfitting not to 

 add at least a few words on the extraordi- 

 nary geographical achievements of the 

 ^Presidential address at the meeting of the 

 Association of American Geographers, held in 

 Cambridge, Mass., December 30, 1909, modified 

 and extended in certain parts.
