( 498 ) 
by a dozen nearly equally broad rings. Therefore, in my opinion, 
this small summer salmon, which was caught in August 1909, was 
probably one of ther winter 1904/1905 spawn. 
Quite in accordance with what X expected I then found that a 
so-called large summer-salmon (of a length of 1.024 m.), caught on 
the same day as the, smaller one just described, and the scale of 
which is represented by the figures 20 and 20a, was still one year 
older to judge from the structure jof that scale. The analysis of the 
scale is the following: 
A rather large central division with 23—25 rings represents the 
first year. 
Roundabout this part the formation of the second year is seen; 
it consists of 6—7 rings formed during the stay in freshwater and 
12—14 formed in the sea and it is separated from the partition 
formed in the third year by an indistinct x ) and narrow ring. 
The part of the third year is composed of about 14 broader rings 
and is surrounded by a group of narrow rings, which probably 
represent those formed in winter time, the breadth of this group 
only slightly increasing towards the middle of the scale. 
Next comes a slightly broader band built up of 17—18 rings. 
This band seems to form the growth of the fourth year and is enclosed 
by a not very prominent winter-band, which consists of five nanow 
rings in the middle, and which greatly diminishes in breadth on 
both sides. 
Upon these we have a much narrower band, which grows extremely 
narrow, in the middle of the scale, owing to the winterband (whic 
separates it from the division formed in the last year of this salmons 
life) being very broad there. This winter band in the middle is compos 
of about 10 narrow rings, the margins of which are very distinct 
and nearly quite parallel to each other. 
Finally we have roundabout that division the part which ie P ie ^f 
the growth of the 6th year, which was broken off in August 
and which shows itself as a band of 16—18 first broader, later o 
narrower rings. 
According to this sketch the ring formed in the fifth year vrw 1 
be remarkably narrow. Have we perhaps to do with one o 
fishes, which visit the river for the second time? And is ^ 
very distinct winter-band between the growth of the 4* h and 5 } 
together with the narrow section of the scale formed in the J 
In the part figured (fig. 20) this separation can only be distinguished ow ^ ^ 
the first ring of the next year being very broad. In fig. 20a it is m ica 
single line.
