For further information on this subject, see Appendix M.—“Pneumatic tubes for the conveyance of telegrams are in use,” I am informed, “between the Central Telegraph Office in St. Martin’s-le-Grand and many branch offices, the longest line of tube being that to the House of Parliament—upwards of two miles. They are also in use in Manchester, Liverpool, Glasgow, Birmingham, Newcastle, and Dublin. In Berlin a costly tube service has been established for the distribution of letters to the various parts of that city.”—Ed.
