loss, while others, in view of the public benefits to be derived from the establishment of the service, were prepared to agree to rates which might prove insufficient to cover the expenses.[601] Simple uniform rates were regarded as a cardinal feature of a postal service for parcels.[602]

After prolonged discussion agreement was finally arrived at, and a Convention was signed by all the delegates, with the exception of those representing Great Britain, British India, Holland, and Persia, to be brought into operation on the 1st October 1881.

Financial considerations were the chief obstacle in the way of the participation of Great Britain.[603]

The contracting parties undertook to provide a mutual service for the interchange of parcels not exceeding 3 kilogrammes in weight. Liberty of transit was guaranteed throughout the territory of each contracting country, and for transit services the respective countries were to be remunerated as follows: The administration of the country of origin was required to pay to the administration of each other country concerned in the transmission, and to that of the country of destination, 50 centimes for each parcel in respect of land transit. In cases where a sea transit was involved, the sum of 25 centimes for each parcel was payable on sea routes not exceeding 500 nautical miles; 50 centimes for routes between 500 and 1,000 nautical miles; 1 fr. for routes between 1,000 and 3,000 nautical miles; 2 fr. for routes

between 3,000 and 6,000 nautical miles; and 3 fr. for all routes exceeding 6,000 nautical miles. The rate of postage was based on the foregoing payments, and amounted to as many times 50 centimes as there might be administrations concerned in the transmission, with the addition of all rates for sea transit, and with the reservation that each country might charge an additional 25 centimes (raised in certain cases to 50, to 75 centimes, or to 1 fr.). In addition, the country of destination might charge a delivery fee of 25 centimes. It was not anticipated that these rates would in all cases be sufficient to cover the expenses of carrying on the service, but the general advantages were regarded as adequate compensation for any monetary sacrifice which might be entailed.[604] Any administration which did not at that time conduct a parcel post service was authorized to arrange for the international service to be undertaken on its behalf by railway and steamship companies.

At the Lisbon Congress in 1886 the maximum limit of weight was raised to 5 kilogrammes, at which point it remains, and special rates were established for parcels which, on account of their size, shape or fragility, were inconvenient for transmission.[605] Such parcels, which had previously been

excluded altogether from the service, were now admitted, subject to a rate of postage 50 per cent. greater than the rate on ordinary parcels.

At the Congress of Washington in 1897, power to charge special rates was given to the administration of British India, viz. a rate not exceeding 1 fr. for land transit, a surtax not exceeding 1 fr. 25 on each parcel posted or delivered in British India, and a scale of rates graduated according to weight on all parcels posted in British India, provided that the average receipt of the Indian administration did not exceed 1 fr. 75 for each parcel.[606] The special transit charge was abandoned at the Rome Congress of 1906.

No changes of importance were made at the Rome Congress of 1906. Several proposals in regard to the maximum limit of weight were discussed. The Bulgarian delegates proposed an increase of the maximum to 50 kilogrammes, but the proposal found no support.[607] The Swiss delegate proposed an increase to 10 kilogrammes. This met with some support; but in view of the practical difficulties which would have been imposed on certain administrations in dealing with parcels of so great a weight, the proposal was negatived.

The Indian delegate proposed the insertion of a provision enabling any country to charge postage on parcels originating in that country according to a scale of weights of its own choice, in substitution for the existing single rate.[608]
