16 ANNUAL PvEPOET SMITHSONIAN INSTITUTION, 1922. 



The Museum acquired durine: the year a total of 859,677 speci- 

 mens. These are described somewhat in detail in the report on the 

 Museum, appended hereto, but it will be of interest to mention here 

 a few of the more important accessions. In anthropology the most 

 important addition was the Herbert Ward African collection men- 

 tioned above. A large collection of the brilliant ancient pottery from 

 the ruins of Casas Grandes, Chihuahua, Mexico, was received through 

 the Archeological Society of Washington, and a remarkable series 

 of aboriginal pottery collected by Dr. J. Walter Fewkes in the 

 neighboring Minibres Valley, N. Mex., was also placed on exhibition. 

 A number of pianos were added by Mr. Hugo Worch to his notable 

 collection, among them a magnificent gilt harpsichord made by 

 Pleyel, Paris. 



In the department of biology the outstanding feature of the year's 

 accessions is the collection of about 100,000 insects collected by Dr. 

 William Mann in South America, especially eastern Bolivia. An- 

 other important collection of insects Avas that made by Dr. J. M. 

 Aldrich in Alaska, which numbered around 10,000 specimens. A 

 considerable consignment of biological material, mostly vertebrates, 

 was received from Mr. Hoy, who has been working in Australia 

 under the auspices of Dr. W. L. Abbott. This material brings the 

 important Australian expedition to a most successful termination. 



In geology a number of valuable additions were made to the 

 collections, among them specimens of Bolivian tin and tungsten 

 ores from Mr. F. L. Hess; rich examples of carnotite and hewittite 

 presented by the Standard Chemical Co., Naturita, Colo.; eight gold 

 nuggets donated by Mr. Frank Springer: a large mass of meteoric 

 iron from Owen Valley, Calif., the gift of Mr. Lincoln Ellsworth, 

 of New York; a number of beautiful and valuable gems purchased 

 for the Isaac Lea collection through its endowment fund; and a con- 

 siderable amount of paleontological material, both vertebrate and 

 invertebrate. 



The divisions of mineral and mechanical technology have devoted 

 their time largely to a more perfect and permanent arrangement of 

 the great amount of exhibition material alreadj^ on hand, while the 

 divisions of history, textiles, and graphic arts report many valuable 

 and interesting additions to their collections. 



In addition to the explorations and field work mentioned earlier 

 in this repoit, the ^Museum sent out or cooperated in various other 

 expeditions. Mr. Arthur de C. SoAverb}^ continued his work in 

 China under the auspices of Mr. Robert Sterling Clark, who gen- 

 erously contributed all the material collected to the Museum. A 

 shii)ment of vertebrates and other biological material was received 

 from this expedition during the year. jSIr. Paul C. Standley,
