104 ANNIVERSARY ADDRESS 



mass (Ba) of high ground, or I will rather use the 

 convenient word " massif," with Mattilees Hill (M) over 

 300 feet high, and Duddo Hill (D) [not Duddo Tower] 

 attached to it on the 200 feet terrain by a very narrow 

 neck just South of Grindon Eidge (Gr). Then there is 

 the Branxton Massif (Br) and the Pallinsburn Massif 

 (P), all over 200 feet elevation. I would call attention 

 to the gateway formed by the near approach of the 

 Duddo Hill and the Pallinsburn Massifs to each other. 

 This is a beautiful bit of river scenery. The Till runs 

 over a rocky bed, with less of sluggish demeanour than 

 is its custom, and the steep banks are clothed with 

 trees, that on the East side being called Black Bank, 

 and that on the West or Pallinsburn side King William's 

 Cover. The opposite cliffs are about 70 feet high, and 

 scarcely 300 yards apart at their summits. A moderate 

 amount of spade labour would seem sufficient to fill up 

 this Black Bank gorge, and block this gateway of the 

 river. Supposing such a barrier to be made, so as to 

 connect the Duddo Hill and Pallinsburn Massifs up to 

 a level of 200 or 220 feet, and a similar barrier made 

 across the Pallinsburn bog, between the Pallinsburn and 

 Branxton Massifs, and again a slightly increased elevation 

 given to the narrow neck joining the Duddo Hill pro- 

 montory to the Barmoor Massif, then what would happen ? 

 Till, disappointed of an outway by the accustomed Black 

 Bank gorge, and failing equally to reach the Tweed 

 (as he may at some former time have done) by the 

 Pallinsburn and Learmouth (L) Bogs, would swell with 

 anger and fill his valley from side to side till his fulness 

 reached the contour line of 200 feet. Then we should 

 see Lake Ewart exactly as here represented. The map 

 (Plate VI.) is a copy of the 6 inch Ordnance Survey, 

 obtained by following the 200 feet contour line. The 

 remarkable shape, especially in the South-east portion, 

 has its parallel in the lakes of Sweden and Finland, 

 nowhere in Britain except perhaps in Lewes. Such
