portion of the first floor were opened in January when the Museum 

 of History and Technology was opened to the public. 



The Railroad Hall interprets the history of street railways, as 

 well as railroads, through a few choice full-scale vehicles and an 

 extended series of accurately and precisely executed scale models. 

 The giant 280-ton Pacific-type steam locomotive No. 1401, largest 

 and one of the most impressive 3-dimensional specimens in the 

 museum, stands near the row of east windows through which it may 

 be viewed from outside of the building at night, as well as by daylight. 

 A cut-away scale model of a Diesel-electric locomotive shows a type 

 that has supplanted the steam locomotive on American railroads in 

 recent years. A full-size cable car used in Seattle, Wash., at the 

 turn of the century stands on a section of narrow-gauge track in an 

 elevated position so that visitors can see the underground construc- 

 tion required for its operation. Basic developments in street cars, 

 locomotives, and railroad cars are illustrated by nearly 80 models, most 

 of them built to the same scale. The hall was planned by associate 

 curator Jolin H. White, Jr., in collaboration with exhibits designers 

 James Mahoney, Virginia Mahoney, and Deborah Bretzfelder. 



Tlie adjacent Vehicle Hall traces the development of various types 

 of road vehicles in the United States from the 18th century to the 

 present day. Among the outstanding horse-drawn vehicles on dis- 

 play are two variations of the famous stagecoach, widely used in the 

 East and West beyond the lines of the early railroads ; the finely con- 

 structed Lawrence family coach built in 1851 ; a city omnibus built by 

 E. M. Miller of Quincy, 111. The automobiles illustrate the rapid evo- 

 lution of automobile design and manufacture from the 1890's. Along 

 with the Balzer and Haynes motor wagons appear the famous Winton 

 mile-a-minute racer of 1902, the Winton in which Dr. H. Nelson Jack- 

 son drove the first transcontinental motor trip in 1903, and a sturdy 

 Mack Bulldog truck. One of the very rare Draisines, known also as a 

 hobby horse, is shown in the cycle collection. Museum Specialist Don- 

 ald Berkebile planned the exhibits in this hall with assistance in lay- 

 out from exhibits designer Riddick Vann. 



The Hall of Tools illustrates the history and development of ma- 

 chine tools. Introductory exhibits display hand tools with which 

 men performed laboriously the same tasks as were later accomplished 

 with much greater speed and precision by machine. A short sound 

 film in color describes the five basic machining operations — planing, 

 milling, drilling and boring, turning, and grinding. The attainment 

 of greater precision in measurement, important to the development 

 of machine tools, is emphasized in a series of exhibits tracing the 

 history of measurement from the Roman cubit to modern times. An 

 outstanding feature of this hall is a reconstructed full-size machine
