The English were slow to utilize or introduce the two-wheeled bogie. From time immemorial the rigid wheel-basewas the fashion in that country. This prevented the sharpcurves which are so common in America and which so greatlylessen the cost of railways.

Because of this the bogie did notin England possess the value it did in America.

He, moreover,possessed those qualities which enabled him toimpress others with the practicability and valueof his conceptions. He was not only a mechan-ical engineer, but a man of talent and affairs inother directions. He possessed a mind capableof considering intelligently and conservativelyany problem brought to his atte
