46 EEPOET OF NATIONAL MUSEUM, 1913. 



pressing tools, etc., and a set of zinc plates showing the method 

 followed in making the colored supplement of a Smiday newspaper, 

 contributed by Ben Day, Inc., of New York; and two sets of pro- 

 gressive proofs of colored lithographic printing, received from the 

 Fuchs and Lang Manufacturing Company, of New York. An inter- 

 esting series of engravings, etchings, mezzotints, maps, charts, and 

 photographs was lent by Mrs. Julian James. The section of photog- 

 raphy received for its exhibition collection an important series of 

 astronomical photographs made at the Mount Wilson (California) 

 Solar Observatory under the direction of Dr. George E. Hale, and 

 presented by the Carnegie Institution of Washington. 



As explained in the last report, the exhibition haUs on the main 

 floor of the Smithsonian building have been assigned to the division 

 of graphic arts, exclusive of the section of photography which is 

 retained in the older Museum building. The installation of the 

 collections, begun in 1912, was actively continued during last year, 

 but, owing to the fact that extensive improvements are about to be 

 made to the main and larger hall, the final classificatory arrangement 

 of the materials has for the most part been deferred, though not to 

 the extent of preventing a generally satisfactory presentation of 

 the several subjects so far as they have been worked up. In the 

 west hall, where the installation has been most perfected, the exhibits 

 are practically all technical, comprising the tools, materials, and 

 finished work elucidating the processes of reproduction along many 

 lines, as in wood and other methods of hand engraving, etching and 

 lithography; photo-mechanical hthography, intagUo, and rehef; 

 coUography, electrotyping, shading mediums, etc. The collection 

 illustrative of photography, which occupies the gallery of the north- 

 west court in the older Museum building, has been so nearly com- 

 pleted as to insure the opening of this important exhibition early 

 in the current year, although many gaps still exist and some time 

 wiU be required to finish the labeling. 



Musical instruments. — The Museum has a large and diversified 

 collection of the musical instruments of both aboriginal and civiHzed 

 peoples, which is at present exhibited under such unfavorable con- 

 ditions that its true value can not be appreciated. A better installa- 

 tion, however, is soon to be made, which it is hoped will lead to 

 further contributions needed to fill m the many existing gaps. The 

 collection has for a number of years been under the custodianship of 

 Mr. E. H. Hawley, who has not only carefully attended to its preserva- 

 tion, but has made extensive studies regarding the properties, dis- 

 tribution, names, etc., of the musical instruments of the world, 

 which has enabled him to so classify and label the Museum material 

 as to give it a distinctive value. There were only two accessions 

 during the year. One consisted of a piano made by Torp and Unger,
