fear of heavier flooding and more serious damages further down, the great outlay 
again required to repair and replace river banks and protection walls would 
naturally cause some hesitation. Between Tynreich and Inch Farm the banks 
have stood well; but at a critical turn on Haugh of Tullymet Farm, where, in an 
extra overflow, a strong stream is carried over the island in front, about 40 yards 
of a gap has been made. (Plate 2.) Our photograph shows both ends of the 
opening, the pool left, of large size, where embankment stood, with the newly 
turned up soil behind, over acres of which piles of stones and gravel now lie. Here 
a considerable part can hardly be cropped this season. At the opposite side of the 
field the rush of water and debris has actually entirely uprooted a bush and thorn 
hedge, with wire fence. Not a trace of hedge is to be seen, and the iron standards 
and straining part of the fence, though embedded in heavy blocks of stone, are 
turned over and displaced like matchwood. Of course there was the combined 
force of the Tay and Tummel, as this part is a little below the junction. On the 
south side, below Balmacneill House there is a tremendous gap made at a spot that 
has not formerly given way. Here heavy silting and excavation have been caused, 
many acres of arable fields requiring extensive clearing. Near Kindallochan, on 
the north side, is seen a remarkable break, where even the thick row of alders 
along the river side has not afforded sufficient protection against the flood, and 
consequently the embankment is entirely gone for a length of over 30 yards. Just 
here is Guay Island, seldom entirely covered, but on this occasion the Shetland 
ponies grazing there ran a very narrow risk, as they were to the neck in water, 
and swimming about in a pool, while a few were washed away. Nearer Guay is 
seen the beginning of a washed-away embankment; in front is the edge of shingle 
at river side ; and when the water had forced its way by mole-holes or water-rat 
workings, in a few minutes sods of grass were torn off, and the soil beneath 
quickly got washed away. When this and the previous gap gave way, there was 
a deep submerging of the fields, roadway, farm house, and buildings at Guay, and 
so suddenly did the rush come down that cattle and horses were standing deep in 
water in their stalls. The sudden rush carried away the banks of the Guay Burn, 
causing a damaging flooding in the Store at Guay (Plate 3), where a tailor, while 
engaged in removing goods, found himself in a muddy stream to the middle, and 
had to be rescued. The height to which the water rose here above floor level was 
30^ inches; while the second high flood, on 22nd February, showed a rise ox n 
inches less. Dowally Farm escaped with flooding, mostly backwater, which left 
an extraordinary amount of debris, including large numbers of drowned rabbits. 
On the Dalguise side, just below the Railway Bridge, there is a tremendous 
gap (Plate 4) of over 100 yards, and terrible destruction was wrought. At this 
point there is a bend in the river course both above the bridge, where bursts have 
been frequent, and below. There was tremendous weight and pressure on the 
embankment, and when the raging floods commenced to wash over, there was a 
rapid break away, and a tearing up of strong retaining walls ; trees were uprooted 
and carried away in a confused heap (Plate 5). On the large tree on the left can 
be noticed the flood record mark, at a height almost incredible. The next view 
(Plate 6) shows the damage along the side of the river to the other end of this gap. 
In front are seen the broken retaining walls, and behind, instead of the embank¬ 
ments, pools of great depth, and a displacement of gravel and soil over the grass 
fields that is extraordinary. A few hundred yards lower, the embankments are 
again washed away, leaving considerable gaps. At Dalmarnock is another break, 
a place that seldom escapes, though a long distance from the regular river channel. 
The surface here is, however, at a low level right across the Dalguise Valley down 
to Inchmagrannachan, and the water, even in an ordinary flood, rises high on the 
railway embankment. From this point the valley narrows to a pass, and till below
