RECORDING SECRETARYS REPORT. 



The Recording Secretary, Dr. Carlos E. Cummings, 

 reported that as a delegate of the Society he attended the Tenth 

 International Geologic Congress at Mexico City in August, 1906, 

 visiting with other delegates the cities of Puebla, Oaxaca and 

 Tehuacan, from which side trips were made to the interesting 

 ruins of Mitla and the cactus country of Zapotitlan. During 

 the sessions of the Congress which were held at the National 

 Institute of Geology, trips were made to Cuernavaca, Pachuca 

 and to the Pyramids of Teotehuacan. At the close of the Con- 

 gress, he visited the coast, passing through Jalapa, Vera Cruz 

 and Orizaba, following this by a thirty days' journey from 

 Mexico City northwest to the American frontier and returning 

 to the Capital. He was thus enabled to secure for the Society 

 a large amount of exhibition material, illustrating the mineral 

 resources of Mexico and also about a thousand photographic 

 negatives from which about 700 lantern slides have been made 

 for lecture work. As will be seen Dr. Cummings delivered 

 four of the lectures in the general course, of which three were 

 descriptive of Mexico, and one of the Island of Jamaica. 



He also reported his trip to the Lake Superior Copper 

 region in June 1906 when he visited the Calumet properties 

 and other mines in the vicinity of Houghton, Michigan, secur- 

 ing many valuable exhibits of copper ores and interesting 

 photographs. 



As a delegate of the Society he attended the meeting of 

 the American Association for the Advancement of Science at 

 New York in December 1906, also representing the Society at 

 the Memorial Services held at Wyoming, N. Y. in honor of the 

 late Professor Henry A. Ward and at his funeral. 



He reported that in addition to his lecture work for the 

 schools he had added largely to our collection of lantern slides, 

 which now numbers nearly 2000 pictures including the Mexican 

 slides, about 300 referring to Jamaica, the remainder illustrat- 

 ing subjects of Nature study. Of these the series illustrating 

 birds and their nests is especially fine and the Society is greatly
