in the Scotch fisheries which seem deserving of atten- 
tion, I venture to offer a few remarks for the consideration 
of the Conference.

There are several kinds of salmon in the Tweed. The 
most common are the Sa/mo salar, or true salmon, and 
the Salmo ertox, which last kind is known also by the 
names of bull-trout, sea-trout, or whitling. But there are 
hybrids which sometimes render identification difficult. 
The young of the true salmon, when first hatched, we 
call a “ parr,’ having dusky cross bars on its sides.

Hatched in December or January, these “parr” go slowly 
down the river towards their ultimate destination, the sea. 
But they do not venture into the sea till another skin of 
glistening scales has been formed over their first skin. 
They then receive the name of “smolts.” . If put into salt 
water, before getting this silver dress, they die. It is only 
a portion of the “arr” which go to sea during the first 
year. The rest, being probably more weakly in constitu- 
tion, remain in fresh water till the following spring, when, 
if not devoured by natural enemies, they also put on a 
silvery dress, and betake themselves to the ocean. 
The “ smolts,” after remaining in the sea for some 
months, return to their native river, having grown to about 
twelve inches in length, and weighing about half a pound 
or more. They then go by the name of “ dlack-tails,” 
having the tail and the dorsal back fin of a black colour. 
They hover about the lower parts of the river, not going 
far beyond the influence of the tide. Before winter they 
return to the sea; and in the following year they come 
back to the river as grilse in June and July. For what 
purpose they come then is not yet known. When they 
come in September and October, it is in most cases to
