report on the operations of the expedition to YUCATAN 

 AND MEXICO. 



The Chief of the expedition, organized under the auspices of the 

 Academy, for the exploration of Yucatan and Mexico, presents the 

 following brief rmtme of the operations which were conducted under 

 his charge. The expedition, consisting of the undersigned, and of 

 Messrs. J. E. Ives, Roberts Le Boutillier, Witmer Stone and Frank

 southwest, to Labna, on the south, to Tunkas, on the east, and to 

 the Port of Silam, on the north. The wonderful caves (Calcehtok, 

 Loltun) and ruins (Uxmal, Labna) of the first range of mountains

 at almost all points touched by the expedition ; some little 

 dredging was also done off the coast at Progreso. Headquarters 

 were established for ten days in the railroad camp of Col. John W.
