SECRETARY’S REPORT 39 
Marchand of Ann Arbor, Mich. The removal of adhering matrix 
and the restoration and mounting of a number of fossil fishes and 
amphibians for display in the hall of cold-blooded vertebrates were 
completed. Retirement of a portion of the geology and meteorite 
collections from hall 6 was undertaken to permit the continued dis- 
play of the larger Pleistocene mammals. 
A group of showy mineral specimens from Arizona and a large 
mass of uranium ore from Colorado were lent for exhibition in the 
United States Pavilion at the Brussel’s World Fair. 
Plans for the modernization of the two halls to be devoted to North 
American archeology were developed by Dr. Waldo R. Wedel, curator 
of archeology. In the first hall now scheduled for construction, 
archeological horizons of the southwestern United States, the Pacific 
coast, and Arctic America will be featured. Topical exhibits will 
show native mines and quarries, Indian smoking devices, and trade 
items found in Indian sites. 
At the close of the fiscal year the contractors had almost finished 
the construction of the walls and display units in the two halls to be 
devoted to the mammals of the world. Preliminary models of the 
habitat groups have been prepared for guidance of the exhibits staff, 
accessories for some of the habitat groups are now ready for installa- 
tion, and a number of mammals required for the display units have 
been mounted. During the year the rooms formerly given over to 
the display of local natural history, other than birds, were more 
urgently needed for other purposes, and, consequently, these displays 
were dismantled. When space becomes available, more informative 
exhibits will be installed. 
The formal opening of the hall of military history on the afternoon 
of June 14, 1958, was presided over by Secretary Leonard Carmichael, 
who introduced the Honorable Wilber M. Brucker, Secretary of the 
Army, who in turn introduced Gen. Lyman L. Lemnitzer, Vice Chief 
of Staff, United States Army, and members of their staffs. Secre- 
tary Brucker made reference to the Institution’s important role in 
encouraging patriotism through the exhibits that interpret the 
Army’s long and distinguished role in the history of our country. 
At the close of these indoor ceremonies, Secretary Brucker was hon- 
ored by a colorful retreat review by the First Battle Group, Third 
Infantry Regiment, on the Mall. In the new hall the history and 
development of the United States Army from the Colonial militia 
to the modern Pentomic Army are traced through the display of fire- 
arms, uniforms, weapons, and other items of military equipment. 
Unique objects on display include George Washington’s sword carried 
in battle throughout the Revolution and the uniform he wore when
