Note 337 — Chapter VII · —Geographical Boundaries

The same process with the same geographical character has been going on in the Sahara, as the French since 1890 have been expanding southward from the foot of the Atlas Mountains in Algeria toward Timbuctoo at the cost of the nomad Tuaregs. Territory is first subdued and administered by the military till it is fully pacified. Then it is handed over to the civil government. Hence the advancing frontier consists of a military zone of administration, with a civil zone behind it, and a weaker wavering zone of exploration and scout work before it.337 Lord Curzon in his Romanes lecture describes the northwest frontier of India as just such a three-ply border.
