 Yeliicles without wheels. 

 Vehicles with wheels. 

 Transportation by water — 

 Rafts and primitive crafts. 

 Sailing vessels. 

 Steamboats and steamships. 

 Electrical engineering — 

 Telegraph. 

 Telephone. 

 Light and heat. 



Motors, stationary and for traction. 

 Machines and appliances of historical interest. 

 Textiles (arranged to show the history of the art of weaving). 

 Animal products (arranged to show the result of human effort in utilizing the 



products of the animal kingdom). 

 Foods (arranged to show the adaptation of the products of the animal, vegeta- 

 ble, and mineral kingdoms to supply food for man). 

 Physical apparatus. 



The most iraj)ortant addition to the transportation collection, from 

 an historical point of view, was a poster, dated October 9, 1821, of a 

 stage-coach line between Providence, Ehode Island, and Worcester, 

 Massachusetts. This poster was presented by Mrs. S. H. Olmstead. 

 The first machine used in the manufacture of baskets, known as the 

 Horton automatic basket machine, was received from Mr. E. G. DuBois, 

 Washington, District of Columbia. The original working model of the 

 first boiler-riveting machine, using steam as the power, was presented 

 by Mr. Charles H. Haswell, New York City. 



In this section the exhibition and study series are combined, and the 

 collections are in fair condition, considering the limited space avail- 

 able. Yery little progress has been made in administering upon them 

 during the year, owing to the fact that the time of the curator has been 

 taken up with other matters. A small synoptical series was prepared 

 for the Tennessee Centennial Exposition. Whenever additional space 

 shall be provided, the collection will be entirel}^ rearranged. 



Three entries were made in the catalogue during the year, embracing 

 the same number of specimens. 



The electrical collections have been increased through the courtesy 

 of Miss ]\Iary A. Henry, who deposited additional specimens relating 

 to Professor Henry's discoveries in electro-magnetism. Some pieces 

 of apparatus were also received from the Smithsonian Institution. 

 Eeg^rding this collectioji Mr. Maynard says: 



An eifort has been made to assemble and place on exhibition the Henry relics, for 

 which a suitable case has been provided. In this undertaking the Museum has 

 received the valuable cooperation of the daughters of Professor Henry, who have 

 deposited many valuable objects illustrating his work and showing iu some measure 

 the recognition he received for it from scientific men throughout the world.
