Minimum gauge railways (illustrated)

In the year 1881, when the Royal Agricultural Society held their show in Derby, it was represented to me that, as many of the members were interested in the cheap transport offered by narrow gauge railways, it would be appreciated if I opened my experimental line at Duffield to inspection during the week. In order to facilitate the comprehension of the objects of this little railway, the late Secretary of the Society suggested that I should draw up a short descriptive pamphlet to place in the hands of visitors. This was done with success and much saving of verbal explanation. Thirteen years later, having added considerably to the rolling stock and improved many of the details, I decided to give a three days exhibition, and to issue a general invitation to all interested in the promotion of such lines, at the same time taking the opportunity to revise and amplify the first edition of this pamphlet.
