Jan., 1907. Annual Report of the Director. 17 



The work of cataloguing and inventorying has kept pace with 

 the accessions in the Department of Geology, all material being entered 

 as received. The total number of entries in the nineteen record 

 books of the department is 63,102, of which 9,367 were made during 

 the year. Approximately two thousand photographs are now 

 preserved in the albums of this department; one hundred and seventy- 

 eight being added during the year. To the series of photograph files, 

 six have been added and one hundred additional photographs filed 

 in them. In addition to the usual entry in the inventory books for 

 the collections of vertebrate paleontology, a card catalogue has been 

 inaugurated, which shows for each specimen its Museum and field 

 number, when collected, locality, horizon, preparation and disposal, 

 and a detailed description. The most important work of labeling 

 performed was that of the systematic mineral collection. This 

 labeling was required by the reinstallation of this collection. The 

 new labels prepared show the name of the species, its number in 

 Dana's system, its common name, if any, its chemical composition, 

 the Museum number of the specimen, and its locality. The labels are 

 of black cardboard and printed with aluminum ink. Each label is of a 

 size to fit the block upon which the specimen is mounted, these blocks 

 being in turn of sizes to fit the specimens. A total of 4,303 labels has 

 been prepared for this collection, 2,871 of which have been printed. 

 For the gem collection of Higinbotham Hall, labels have been pre- 

 pared in part. These labels are printed with black ink on white 

 cardboard to match the pads on which the gems are mounted, and 

 correspond in size with the pads. They show the name and locality 

 of the specimen, and, in the case of cut stones, the weight in carats. 

 A total of 300 labels has been provided for this collection and in 

 addition eighteen case labels. Labels have been prepared for the 

 .collections of Hall 78 throughout, a total of 744 labels having been so 

 prepared. These labels show the name of the specimen, its Museum 

 number, and the locality whence obtained, and also state any special 

 uses or characters of the material. Other labels prepared in the 

 Department have been chiefly for new specimens installed. These 

 include 68 labels for fossils, 206 for meteorites, 240 for ores, and one 

 large descriptive label for the relief map of Niagara River. 



In the Department of Zoology the work of inventorying, cata- 

 loguing, and labeling has claimed careful attention. The exactness 

 and minuteness of the catalogue of the Illinois bird collection may be 

 especially noted. In the division of mammalogy much time has been
