“ The Gabun colony includes the Gabun estuary and the whole of the coast-line of French Congo, together with the basin of the Ogowé river. The inland frontier is so drawn as to include all the hinterland not within the Congo free-trade zone (the Chad district excepted) . The Middle Congo has for its western frontier the Gabun colony and Cameroon, and extends inland to the easterly bend of the Ubangi river; the two circumscriptions extend east and north of the Middle Congo. There is a general budget for the whole of French Congo; each colony has also a separate budget and administrative autonomy. ”
