1. On High Flood Marks on the Banks of the River Tweed and some of its tributaries, and on Drift Deposits in Tweed Valley

In many parts of Scotland there are indications that our existing rivers reached much higher levels than at present, and that large bodies of water prevailed over districts which are now dry land.

As these facts suggest important speculations as to the physical conditions and climate of the country, it is desirable that they be investigated, before becoming more indistinct from the combined effects of weather and land improvements.
