THE history and antiquities, the fauna and flora of Deeside, have
received fairly adequate attention : its solid geology has been mapped.'
But little notice has been taken of its physical features except in their

the more notable of these features from a strictly scientific standpoint.
I. THE PROBABLE AGE AND ORIGIN OF THE DEE VALLEY ||
II. GRADIENT OF THE RIVER BED ||
III. CAPTURE OF THE HEAD- WATERS OF THE RIVER BY TRIBUTARIES OF THE

IV. RELATION BETWEEN THE COURSE OF THE RIVER AND ITS TRIBUTARIES
AND GEOLOGICAL STRUCTURE . V. EFFECTS OF ICE ON THE PHYSICAL FEATURES OF THE VALLEY: I. ICE- ABRASION; 2. ICE- EROSION; 3. BOULDER -CLAY; 4. MORAINES; 5. KAMES; 6. OVERFLOW CHANNELS AND GLACIAL LAKES ||
VI. SPECIAL POINTS REGARDING TRIBUTARIES ||
