Flattering reviews of Russian and foreign journalism about the second edition of my Collection of Statistical Information on Railways in Russia prompted me to publish the third issue. When compiling my new work, I tried to determine as accurately as possible the current situation of railway affairs in Russia. Unfortunately, statistics on this subject have so far been kept extremely superficially and with insufficient detail, so I was forced to exclude several tables that I intended to place in this work, for lack of positive data. To avoid such omissions and for the future, I appeal to all the Boards of private Railway Societies with a humble request whether they recognize it possible to deliver the missing information to me. To achieve this goal, I submit to each board of the Company a copy of a new Collection with the attachment of a list of information not included in it, which can be of considerable interest to everyone involved in railway issues in Russia.
