SUMMARY.
We have shown that the recent physical history of the region is legibly recorded in glacial sculpture and moraines, in orogenic movements, in valley cutting and terracings, in lake expansions, and in the building up of the plains, and we have made some progress in correlating these events.
We have also found full confirmation of the statements as to a progressive desiccation of the region of long standing, which has from a remote period continually converted cultivable lands into deserts and buried cities in sands.
We have found, widely distributed, great and small abandoned sites of human occupation, with evidences of great antiquity.
We have reason to think that a correlation of these physical and human events may be obtained through continuance of the investigation, and that archeological excavations will throw light on the origin of Western and Eastern civilizations.
