The new conductors were dressed in dark velvet suits, and as far as politeness was concerned were all that could be desired. Unfortunately they became possessed of the belief, not yet quite extinct, that to rob an omnibus proprietor was no sin. The amount of money handed in to Shillibeer grew less daily--a very suspicious decrease, considering that people living on the road which the omnibuses travelled declared that the vehicles were as well patronised as ever. Shillibeer therefore made arrangements with various trustworthy people to ride in his omnibuses, as ordinary passengers, and check the number of people carried and the amount of fares which they paid. For a few days every journey that the omnibuses made there was a male or female passenger watching the conductors, and from their reports Shillibeer discovered that the two men were, between them, robbing him to the extent of £20 a week. This was corroborated by the conductors themselves, whose style of living had become decidedly luxurious. In their time of affluence they did not forget their poorer friends, and one night, after work was finished, they treated a number of them to a champagne supper at the Yorkshire Stingo. The whole party became hilariously drunk, and while in that condition the hosts threw discretion to the winds, and bragged loudly that they made £10 each a week out of the omnibuses, in excess of their pay. Among their guests were detectives employed by Shillibeer, who repeated the confession of fraud to their employer, with the result that the first professional omnibus conductors were discharged. Shillibeer’s leniency, due to his anxiety not to have his omnibuses mixed up in any scandal, encouraged succeeding conductors to steal. Shillibeer was at his wits’ end what to do, when a man called on him with a patent register guaranteed to put a stop to the conductors’ pilferings. The register was designed to be placed underneath the omnibus, and people entering or leaving the vehicle trod on a plate fixed in the step, the register recording every person who stepped upon it. Shillibeer liked the idea, and bought one of the registers on the condition that the inventor acted as conductor until its reliability had been proved thoroughly.
