The scientific program consisted of a paper by Dr. Francis 

 W. Pennell on "A Collecting Trip to Colombia," an abstract of 

 which follows: 



A brief account was presented of the speaker's experiences in 

 Colombia between July, 1917, and March, 1918. During the 

 first portion of this time he had accompanied Dr. H. H. Rusby; 

 after August 20, he was alone. Joint travel comprised the 

 ascent of the Magdalena valley to Neiva, thence across the 

 Eastern Cordillera to the hacienda of "Balsillas." Later travels 

 were: about Bogota; across the Eastern Cordillera to Villavicen- 

 cio at the head of the plains of the Meta ; to Fusagasuga and the 

 Natural Bridges of Pandi; the ascent from San Lorenzo to the 

 snow-crowned Paramo de Ruiz in the Central Cordillera; across 

 the plains of Bolivar from Magangue to Monteria; up the Rio 

 Sinu andascent of the Western Cordillera to the Paramo de 

 Chaquiro. Throughout the portion of Colombia seen, phy to- 

 geographic areas are sharply marked; in the lowland into forest 

 or prairie; upon the mountains into zones dependent upon 

 altitude. The latter are homologous, yet at increasing elevation 

 progressively different in composition, upon each of the three 

 Cordilleras.
