greatly enriched the collection of Cambrian fossils, and field work in 

 Tennessee by Doctor Bassler and the Hon. Frank Springer resulted 

 in an important accession. Twice during the year the head curator 

 was called on for service not directly connected with his Museum 

 duties; first, in July, 1910, to inspect limestone quarries at Bedford, 

 Indiana, with a view to the adoption of the stone for the St. Alban's 

 Cathedral building in Washington, and a^ain in May following, at 

 the request of the Secretary of the Interior, to inspect the fossil 

 forests near Adamana, Arizona, for the purpose of setting aside cer- 

 tain areas from which collections may be made, and also of reducing 

 the size of the reservation. Incidentally, he obtained a considerable 

 quantity of silicified wood for exhibition and study purposes. 



DISTRIBUTION AND EXCHANGE OF SPECIMENS. 



The only duplicates arranged in systematic series, to meet the 

 needs of educational establishments, available for distribution during 

 the year, were fossil invertebrates. Of these^ 27 sets, aggregating 

 1,393 specimens, were supplied to as many schools and colleges. In 

 meeting special applications for teaching purposes, 697 duplicate 

 specimens of animals and plants and 1,094 duplicate specimens of 

 rocks and fossils, besides some 3,350 pounds of assay and blow-pipe 

 material, were distributed. For making exchanges, 23,582 duplicate 

 specimens were used, of which 88 were anthropological, 22,160 bio- 

 logical, and 1,334 geological. There were sent to specialists for study,
