MUSEUM NEWS NOTES 79 
extinct fauna collected in caves in Arkansas by Messrs. Walter 
Granger and Barnum Brown in 1903 and 1904, on expeditions 
sent into the region by the Museum. 
Earzy in March, Mr. Frank M. Chapman, Associate Curator 
of Ornithology, went into the swamps of Florida for the purpose 
of studying the life history of the Brown Pelican and of obtaining 
additional material for the group illustrating this remarkable 
bird. He reports exceptional success in attaining the objects of 
the expedition. He has also obtained data, photographs and 
specimiens with which to represent the nesting-habits of Ward’s 
Heron, the Water Turkey and other birds, greatly enriching our 
Museum and study collections. 
InN commemoration of Audubon’s one hundred and twenty- 
fifth birthday, the Museum has placed on exhibition in Hall No. 
308, a collection of Audubon relics. Among the objects is the 
portfolio in which Audubon carried specimen plates while secur- 
ing subscribers to his great work in this country and abroad, 
together with sketches and finished plates. Here are also his 
gun and hunting coat, and the dog harness used in Labrador, 
mementoes of the journey to the then Far West. 
Dr. E. O. Hovey, Associate Curator of Geology, went to 
Mexico early in February on a geological expedition through the 
practically unknown Sierra Madre mountain region of western 
Chihuahua. He reports visiting a wonderful series of cafions, 
from 2000 to 6000 feet in depth and from 5 to 11 miles in 
width, which have been carved by the rivers out of the elevated 
plateaus forming the major portion of the state. Dr. Hovey has 
also visited the great copper mines at Bisbee, Arizona, and 
Nacozari and Cananea, Sonora, Mexico. The specimens col- 
lected from these mines, as well as from the region traversed in 
the main expedition, will form valuable additions to our series 
illustrating economic and mining geology. Hundreds of nega- 
tives form an important part of the results of the expedition. 
Professor Robert T. Hill, formerly of the United States Geo- 
logical Survey, is the leader of the party.
