7. Start Fishery (south side of} 52 56 | 7. The bank, and the flat stretching from it, are 
river), striking objects. The bank here is above the 
O.8. 50 feet contour. Height above river, 
ascertained by aneroid. 
The bank is continuous here for nearly half 
a mile, On examining this bank by a tele- 
scopic spirit-level, along a distance of about 
600 yards, the base of the bank is found to 
slope down eastwards several feet ;—it is 52 
feet above river at westermost point. 
The bank at its east end has a remarkable 
curve towards the S.E., as if the river formerly, 
or a branch of it, had flowed in that direction 
round the knoll K on map (see Plate XXXV.). 
In the field S. W. of Yard Ford houses, which is 
about 38 feet above the sea-level, there is an 
indication of an old water course having 
flowed towards the east. 
When the telescope level, planted at the base 
of the bank, is directed to the bank on the north 
side of the river, the following is the result. The 
bank at Gainslaw towards the east, is a few feet 
lower than the ground on which the telescope 
stands. Thereare banksand flatsin Paxton Policy 
on the north bank immediately opposite, which 
correspond in level. There is a bank at Tweed- 
hill (z.e., up the river) slightly above the level. 
8. Paxton Policy. In the Tweed] 53 54 | 8. The terrace in the field is interrupted by a mass 



braes old grass field, and in | of rock, standing about 20 feet above it, and on 
the plantation to the west, which there is no river marking. The banks 
there are flats bounded by a east and west of this rock, consisting of softer 
steep bank (north side), materials, being capable of erosion, show a cliff. 
The river, when it formed these banks on 
both sides in this part of its course, must have 
inclined to run as at present, more towards the 
north than towards the south. That is to say, 
the current must have been most rapid on the 
north side, so that sediment brought down by 
floods would’ be deposited chiefly in the stiller 
water on the south side. Hence on the north 
side, in this part, the bank is much steeper than 
that on the south side, and the flats bounded by 
the flood lines at both heights (viz., the old one 
at 43 feet, and the existing one at 19 feet above 
the river) are much narrower on the north than 
on the south side. The inclination of the stream 
towards the north may be accounted for by 
the circumstance that about half a mile up 
the river, there are high rocks on the south 
side, causing the river to slant off in a N.E. 
| direction, even from an early period, when the 
river occupied a channel from 40 to 50 feet 
above the present channel. 
9. Tweedhill Policy (north) 54 57 | 9, There is a bank (east of the house) facing the 
side), river, the upper part of which is covered with 
trees, the lower part reaching down into an old 
grass field where it meets a terrace. The spirit- 
Jevel on this terrace coincides with the base of 
the bank on the south side of the river. The flat 
and its bank are continued in the field west of 
Tweedhill House; and will be found to be on ex- 
actly the same level as the base of the projecting 
rock No. 10 on the opposite side of the river.
