REPORT OF liTATIONAL MUSEUM, 1923, 



believed that the cylinder which the Museum has is an original part 

 of that locomotive or if not, it is at least a copy. 



H. W. Dickinson, deputy keeper of engineering. The Science 

 Museum, South Kensington, London, made a general study of the 

 collections of the divisions but particularly the mechanical engineer- 

 ing collections, and was of valuable assistance in clearing up doubt- 

 ful points pertaining to the early steam engine and locomotive devel- 

 opments in England. 



Rev. F. A. Jefferd, of the Amazon Mission, Brazil, made a close 

 study of the boat collections, particularly of schooners. His pur- 

 pose is to construct a schooner having several distinctive features 

 such as control of all rigging from the boat deck, in which craft and 

 with a crew of Amazon Indians who are members of his mission, he 

 plans to make a round-the-world missionary cruise. 



DISTRIBUTION AND EXCHANGE OF SPECIMENS. 



Except in the particular case of a few objects of extreme impor- 

 tance in the history of the United States, the collections of the divi- 

 sions do not include duplicates, so that the divisions do not have the 

 opportunity of distributing materials to schools and other educa- 

 tional institutions. Such duplicate objects as are in the possession 

 of the divisions are loaned occasionally for special purposes. In this 

 connection several of the historical boat models, copies of the origi- 

 nal Bell telephone apparatus, primitive carts and other objects per- 

 taining to transportation were loaned for the Pageant of Progress 

 Exposition held at Chicago during July and August, 1922. 



To commemorate the work of Elwood Haynes, a pioneer auto- 

 mobile manufacturer, the original Haynes automobile was loaned to 

 the Chamber of Commerce of Kokomo, Ind., during the month of 

 July, 1922; and copies of the original Morse telegraph instruments 

 were loaned to the All America Cables Company for use in their 

 exhibition at the Centennial Exposition, Eio de Janeiro, Brazil. 

 Furthermore, quite a number of exchanges of photographs of loco- 

 motives were made during the year with collectors in many parts of 

 the country.
