28 ANNUAL, REPORT SMITHSONIAN INSTITUTION, 19 31 



Skiiuier, Mrs. F. B. Plummer, and Dr. T. Wayland Vaughan, Many 

 valuable specimens, particularly of fossil mammals, were obtained 

 from collections by C. W. Gilmore in the Eocene deposits of Wyo- 

 ming, among them being several nearly complete skeletons that will 

 eventually be mounted and placed on exhibition. There may be 

 mentioned especially a nearly complete skeleton of Hyrachyus, a 

 rhinoceroslike animal about the size of a tapir, a nearly complete 

 skeleton of Orohi'ppus^ a small primitive horse, and two more or less 

 complete crocodile skeletons; 38 turtles were obtained belonging to 

 eight genera. Additional fossil horse material resulted from field 

 explorations near Hagerman, Idaho, under Dr. J. W. Gidiey. 



The collection of fossilized tracks of animals was augmented by 

 an unusually distinct dinosaur footprint from the Triassic of 

 Virginia, presented by F. C. Littleton, of Aldie, Va. Fossil bird 

 bones, types of new species described by Doctor Wetmore, were pre- 

 sented by Dr. E. L. Troxell, of Trinity College, Hartford, Conn. 

 To the exhibitions in the section of paleobotany there came a fine 

 example of a fossilized tree from near Natchitoches, La., presented 

 by George Williamson tlirough the interest of Prof. E. W. Berry. 



Arts and industries. — An important accession in the aircraft sec- 

 tion was a series of objects illustrating the first use of aircraft for 

 military purposes in the United States, relating to captive balloons 

 used during the Civil War, the collection having come from Prof. 

 Thaddeus S. C. Lowe, organizer of the first military balloon section 

 of the Federal Army. The airplane Bremen, the first heavier-than- 

 air craft to make a nonstop flight westward across the north Atlantic, 

 was deposited by the New York Museum of Science and Industry. 

 For the section of land transportation there was secured a coachee, 

 or light family carriage, made in Philadelphia about 1783 that there 

 is reason to believe was owned at one time by General Washington 

 at Mount Vernon. An original Concord stage coach was deposited 

 by Will Rogers and Fred Stone. The Philadelphia Electric Co., 

 through its president, William H. Taylor, presented a model of a 

 section of the Conowingo hydroelectric generating station on the 

 Susquehanna River near Conowingo, Md. Another valuable acces- 

 sion was an original horizontal stationary steam engine built in 1864 

 in the shops of the United States Military Railroad Department at 

 Alexandria, Va., presented to the Museum by the Southern Railway 

 system. This engine was in operation for 58 years. 



The Pepperell Manufacturing Co. presented a model exhibit cover- 

 ing the growth and manufacture of cotton. A number of interesting 

 examples of hand-woven textiles from several individuals included a 

 linen damask tablecloth woven in Vermont about 1780, the design 

 being an illustration of Independence Hall, Philadelphia. This was
