The weight ofthe locomotive was taken by wheels, C C, fore and aft. Thefollowing defects were observed :—The frictional surfaces, bothin the upper and lower nests, were too small, and the materialstoo soft, so that rapid wearing resulted with a consequent in-crease of friction. Moreover, the grip was so powerful, that therollers, A A, were capable of supporting the weight, and thus asmall inclination of their vertical axis was enough to cause the.
