1897-98.] Migratory Movements of Salmonidce. 53 
If, now, we compare the salmon and sea trout columns of the 
above table (p. 4), we find that, of 320 fish, 172 were salmon and 
148 sea trout. The 58 days’ observations shown in the table begin 
and end with records of salmon , which are, however, noted on only 
47 days of this period. The arrival of the sea trout is later by 6 
days, being on 16th Nov. Their disappearance, on the other hand, 
is earlier by 8 days, being on 13th Jan. They are recorded 
on 36 days ; and both species together are recorded on 25 days. 
During the four weeks (32 days) from 8th Dec. to 8th Jan. the 
figures become higher than at any other time during the season. 
Not only the greatest number of fish, but the heaviest fish appeared 
at this time. 
It may be remarked, however, that the majority of the sea trout 
arrived before the largest runs of salmon, for if we compare the 
first 16 days of this period with the second 16 days, we find that 
the totals are as follows: — In the first 16 days, 104 sea trout and 
32 salmon ; in the second 16 days, 80 salmon and 8 sea trout. 
The very great amount of poaching which is practised almost 
openly in Tweedsmuir district makes it impossible to say how long 
kelts remain after spawning. As a matter of fact, I believe very 
few fish are allowed time even to deposit a limited number of their 
ova. On one of my visits to the district, an old and experienced 
poacher expressed the opinion that not more than one fish in 
twenty escapes the leister. 
Turning now to the consideration of the river Tweed, in the 
neighbourhood of Tweedsmuir, particulars were collected similar to 
those described for Talla Water. The part of the river Tweed 
under observation was about six miles in length, viz., from Stan- 
hope up past Talla-mouth to Tweedhope. As compared with the 
320 fish in Talla, the total number of fish in this part of Tweed 
during the same time was 684, being 512 salmon and 172 sea 
trout. 
The majority of those fish were noticed in Tweed below Talla 
in 4 miles of water. In the 2 miles above Talla only 59 fish in 
all were counted. 
As might be expected, the order in which the fish arrived, and 
the relative numbers, bear a more or less close resemblance to the 
conditions already described for Talla.
