In districts where sub-post-offices are established, the District Commissioner sees to the strict observance of the instructions regulating the important postal service.
It has been found that in several districts the services of soldiers in the garrison have been utilised for the mails. Not only did these not always render the services which workmen or other men specially engaged for the service of transports of all kinds render, but even there was reason to fear that the soldiers, on account of their uniform and arms, as well as being without control, sometimes abused their powers to make levies on the villages through which they passed. But now the strict instructions of the Government forbid soldiers being taken away from their garrison and military duties, and require that they should always remain under the control of their chiefs. It has, therefore, been positively forbidden to send any mail by soldiers of the Public Force.
TELEGRAPH AND TELEPHONE SERVICE
On 27th November, 1893, the State ordered by decree the first telegraphic line, and in July, 1895, a first wire was stretched across the river; and on 15th September, 1898, it became possible to telephone and telegraph from Boma to Leopoldville, or for a distance of 452 kilometres (282 miles). Later on, and when the transport of material had been made easier by the opening of the Matadi-Leopoldville railway, the telegraph line was extended to Coquilhatville.
At the present moment there are thirteen telephone and telegraph offices working in the State.
The principal offices and distance separating them from each other are:
| Boma-Matadi | 52 | kilometres |
| Matadi-Tumba | 185 | ” |
| Tumba-Leopoldville | 215 | ” |
| Leopoldville-Kwamouth | 233 | ” |
| Kwamouth-Mopolenge-Yumbi | 177 | ” |
| Yumbi-Lukolela | 121 | ” |
| Lukolela-Irebu | 102 | ” |
| Irebu-Coquilhatville | 114 | ” |
| Total | 1,199 | kilometres[22] |
(nearly 750 miles) of development. This extensive telegraph and telephone line is carried on iron posts from Boma to Leopoldville, and from Leopoldville to Coquilhatville the wire is supported in some places on steel posts, in others on trees, in the proportion approximately of 4494 steel posts and 2782 trees.
The line has to make two very important crossings of water, one across the Congo a little above Underhill Point (Hell’s Kettle), the other across the Kassai near its mouth.
At the crossing of the river at Underhill the wires are supported by trellised steel towers, the piers of which are distant 800 metres from each other; and they are placed 73 and 63 (2) metres[23] respectively above the bed of the river at the highest flood.
