304 REPORT OF NATIONAL MUSEUM, 1889. 



logue on March 31, 188S, the time when the first arrangement of speci- 

 mens in the Museum was completed, to 2894 on June 30, 1889, making 

 necessary a re-arrangement and expansion, the whole of the northwest 

 range was given up to the section of graphic arts, the casts from Mexi- 

 can sculptures, etc., which had occupied its eastern half having been 

 removed to the Smithsonian building, and the exhibition as it stands 

 at this writing was put into place during the months of May and June, 

 1889. As arranged at present, the eastern side of the hall is occupied 

 by the technical exhibition, illustrating the older processes of producing 

 pictures for multiplication in the press (relief engraving, intaglio en- 

 graving, lithography, and the substitutes devised to take the place of 

 these processes), aids in drawing used by engravers and by draughtsmen 

 for photo-mechanical processes, methods of reducing and enlarging, and 

 the modem photo-mechanical processes (phototyping, photogravure, 

 photolithography, collographic processes, Woodburytype, etc.). On 

 the western side are shown the specimens illustrating the various 

 methods of drawing and painting, with the monotype, and the histor- 

 ical collection of relief engravings, intaglio engravings, lithography, 

 and color printing. As an appendix there have been added some speci- 

 mens showing the industrial applications of printing. The collection 

 of photographs, illustrating the history of painting, is also displayed 

 on this side of the hall. The arrangement adopted has already, how- 

 ever, shown itself inadequate, and a re-arrangement and filling up of 

 gaps is impending, although the lack of space will preclude any con- 

 siderable further expansion. 



It has been impossible, of course, to place on exhibition all the ma- 

 terial collected, and the large number of specimens left over has been 

 roughly arranged, under technical headings, in two storage cases. As 

 the collection grows, it is to be hoped that this mass of interesting and 

 valuable material may be made available to students. For the present, 

 all that can be done is to provide for its safe-keeping. The culling and 

 arrangement of duplicates, to be used for exchanging, also remains to 

 be attended to. It is not to be expected, however, that this feature will 

 attain the same proportions iu the section of graphic arts which it has 

 attained in other departments of the Museum, dealing with the prod- 

 ucts of nature. During the period covered by this report only one 

 specimen has been obtained by exchange. 



A most valuable subdivision of the section, specially important from 

 its practical bearings, is that devoted to patents relating to all the 

 graphic arts, including the modern photomechanical processes. Under 

 the direction of Mr. J. W. Osborne, of Washington, who has given his 

 advice and time gratuitously, lists of such patents issued in all coun- 

 tries are now being made, and many of them have already been pro- 

 cured. But the completion of this work and its utilization by the 

 public must be deferred to the future. 



A pressing necessity, finally, is the labeling of the specimens ex-
