The efforts of Mr. Charles Waldach to take photographs by aid of 

 magnesium light resulted in a number of interesting pictures of locali- 

 ties in Mammoth Cave. His magnesium alone cost him $500. But 

 for practical use these photographs were not found so desirable as a 

 series of sketches, made in black and white, under my supervision, by 

 Mr. J. Barton Smith. This artist also made the sketches from Wyan- 

 dot Cave. These were prepared for the lantern by Mr. J. M. Blake, of 

 New Haven. The advantages for taking views in Luray Cavern were 

 superior, since it was lighted by a series of electric lamps placed at the 

 most interesting loca;lities. The thirty-six lantern views now shown 

 to illustrate Luray Cave, were taken and prepared by Mr. C. H. James, 

 of Philadelphia. Special mention should be made of Col. Francis 

 Klett, manager of Mammoth Cave, and Mr. R. R. Corson, manager of 

 Luray Cavern, by whom every needed facility was cheerfully given for 

 obtaining the facts of a scientific nature sought, and also the pictorial 

 representations exhibited of subterranean scenery. 



At the close of the lecture a resolution was passed, conveying 

 thanks to Mr. Hovey, for his very interesting and instructive lec- 

 ture.

The audience filled the large hall. 



A lecture was delivered by Dr. J. S. Phene, of London, 

 England, illustrated with a large number of diagram views, and 

 entitled : 



RECENT ARCHAEOLOGICAL DISCOVERIES RELAITNG TO THE MOUND- 

 BUILDERS. 



At the close of the lecture the President remarked that the 

 geological evidence rendered it by no means impossible that the 

 theory of the lecturer might be well founded, of the contempora- 

 neous existence of the mound-building race with the ancient horse, 

 whose remains, exactly like those of the modern horse, have been 

 found in deposits of very recent age in Oregon, etc., and with an-
