T"progress which is being made in the development of the portable machine for ticket issuing and printing, suitable for use by the conductors of public-service vehicles, is slow, but may be said to be sure.
The chief requirements of such a device are that it shall be compact, light in weight, free from liability to mechanical breakdown or jamming, easy to operate, accurate, and proof from tampering. It would appear that two specific types are necessary, one for the Metropolitan and other city areas where there are extremely short stages, and fares practically always under one shilling, and the other more suitable for long-distance work involving tickets representing fairly large amounts. It may, of course, be possible to combine these functions in the one machine, but whatever be done, the requirements for London should not be considered as resembling in any way those of the greater part of the remainder of the country.
