478 PROCEEDINGS OF THE ACADEMY OF [1890. 
appointed Reception Committee, were held in the early part of the 
year, and one in December, and their success fully testifies to the 
wisdom of the course suggested, and justifies the continuance of the 
same in the coming year. No expense is entailed upon the Academy 
as a body, the subscriptions to the Reception Fund being borne 
individually by such members of the institution as wish to partici¬ 
pate in the meetings.

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 resume 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 
C. Baker, sailed from New York on February 15th, arriving at 
Progreso, Yucatan, on the 22d of the same month. A full month 
was spent in the exploration of the northern portion of the penin¬ 
sula, the operations of the party extending to Calcehtok, on the 
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 
w T ere incidentally visited, and collections of various kinds made 
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. 
Glenn, constructing engineer of the railroad connecting Tekanto 
with Izamal, where the most liberal hospitality was extended to the 
members of the party, and facilities furnished for the prosecution 
of their work. To the generosity and courtesy of Colonel and Mrs. 
Glenn the expedition is largely indebted for the success of its Yuca¬ 
tan explorations. 
On the 23rd of March the expedition sailed from Progreso to 
Vera Cruz, the remainder of the explorations, extending into June, 
being conducted in major Mexico. 
The route of travel embraced the principal sites of (recent) 
volcanic activity in the Republic, and thus permitted of a close ex-
