hour. This same report states that up to 1856 the locomotive 

 operated on a steam pressure of 70 pounds per square inch, 

 and thereafter, until it was taken out of service in the early 

 1880's, on45 pounds. 



The locomotive was operated in an unusual manner. The 

 engineer was stationed at one end, adjacent to the cylinders 

 and driving gear, while the fireman was located at the other 

 end, from which the boiler was fired. 



The boiler is about 1 3 feet long and 4 feet in diameter, and 

 has a large U-shaped return flue. The cylinders are mounted 

 vertically at the rear, and the piston rods are guided by 

 Watt's parallel motion instead of the usual cross heads and 

 slide bars. The engine has no frame, the axle bearings being 

 bolted to brackets riveted to the under side of the boiler. 

 Only the front and middle axle bearings are fitted with 

 springs. 



In the course of its working career, the Samson traveled 

 considerably. In addition to having been brought across the 

 Atlantic, the old locomotive was brought to Chicago in 1883 

 for display at the Exposition of Railway Appliances (figure 

 54). There it was accompanied by George Davidson, long its 

 engineer and said to have come with it to Nova Scotia from 

 England. 



Ten years later, in 1893, it was again brought to Chicago, 

 this time to be exhibited at the World's Columbian Exposi- 

 tion. At the conclusion of the exposition the Samson, and the 

 Albion that had accompanied it, were taken by the Bahimore 

 and Ohio Railroad Co. to Baltimore for preservation there. 

 The B & O later included the Samson (and also the Albion) in
