Of course, the rule of self-support should, in like manner be maintained in every other department of postal service. And this, I may remark, would furnish the means for a just increase of advantages in those districts or departments in which receipts may be found to be much in excess of expenditure; an arrangement which would perhaps include the establishment of tubular conveyance[243] to a limited extent in certain directions, and would certainly give to many of our great manufacturing and commercial towns either an increase in the number of deliveries, or of mails. In order that economic improvement may not be unduly encumbered with fixed arrangements, it would be well to limit the duration of all future contracts to some moderate period, say three years; but, under this restriction, it is very desirable for the sake of economy, and for other important considerations, that the contract system should be greatly, though gradually, extended. Experience may show that it may safely and advantageously be made to include the whole postal work at the provincial offices, and various separate departments in the offices within the metropolitan districts, not wholly excluding the Chief Office itself. I may add that the benefit of this change would be greatly increased if the proposed contractors, adopting views now gradually gaining ground, should arrange to give their respective subordinates a direct interest in the energetic and economical performance of the service. Independently of the moral benefits consequent upon the abolition of private patronage, I believe the direct financial advantage, which might be expected from the faithful adoption and rigorous execution of this principle, would be, as I have already said, an eventual saving of probably not less than £250,000 a year. Judging by what has been done at the various telegraphic offices and elsewhere, and bearing in mind the change now steadily progressing in public opinion, I should hope that one beneficial effect of an extension of the contract system would be that female labour would be admitted to a much larger share in postal employment--an improvement which my brother and I always had much at heart.[244] Of a Parcels Post I have already spoken; and I am confident that, whenever established, provided of course that it be on good arrangements, its benefit will be great. I have already indicated the desirableness of lowering the rate of inland letter postage from a penny per half-ounce to a penny per ounce--a change which would obviously give much relief as regards heavy letters. My brother Frederic twice formally proposed, once under Lord Stanley of Alderley, and once under the Duke of Montrose, that negotiations should be entered into with a view to establishing throughout Europe an international postage on a low uniform rate, submitting, to that end, a complete plan; I need not enlarge upon the political, moral, and commercial advantages of so comprehensive an improvement.[245]
