he 
Scarborough vessels were fishing close to the coast in the vicinity 
of that port. 
Whilst the difference of a week in the catches made off the 
Northumberland coast and in the vicinity of the Dogger Bank 
cannot be taken as referring to migrations of the same shoal of 
herrings, the nearness of the grounds fished by Dutch luggers and 
Grimsby vessels suggests the idea that the herrings were moving 
in a south-westerly direction. This idea is strengthened by the 
first signs of increased catches appearing in the north-east portion 
of the area fished by Dutch luggers in the week ending 18th 
September. The average number of barrels caught in the different 
portions of the area was as follows :—

Further evidence of a south-westerly movement of the herrings 
is afforded by the catches of spent fish made by Dutch luggers, 
and the value of this evidence is increased by the fact that no 
spent fish appeared in the catches previous to the first catch of 
spawning or “running” fish on the grounds. The first of the 
spawning fish were noticed on 7th September, but it was not until 
the 15th that any quantity was caught. The quantities of spent 
fish were not great until 21st September, and the first recorded 
for the grounds were caught on the Sth. Spawning took place 
in an area bounded by 54° 22’ to 55°.5’ N.7 1° to 1750 Shee 
chiefly in 54° 40’ to 55° 5’ N., 1° 80’ to 1° 50’ E. Spent fish were 
caught practically all over the grounds. The south-westerly 
migration of spents is best seen in the early period when spawning 
fish and spents appeared, up to 23rd September, and if the region 
fished and catches made be arranged as below the migration is 
apparent,
