In an English case decided by the learned judge DU PARCO hire or reward is explained as under: “It appears to me that a distinction falls to be drawn between the word ‘hire’ and he word ‘reward.’ The first word necessarily imports an obligation to pay. The inclusion of the second words in not in my opinion merely for the purpose of giving an alternative word to hire, which means the same thing, but for the purpose of bringing a subject matter which does not include hire and including (I do not say it is confined to that) cases where here is no obligation to pay.”
