gills. These kelt grilse keep on re- 
turning until December, and spawn 
the same season (Fig. 39). 
I will now treat of what becomes 
of the small spring fish kelts (Fig. 
40)—those from December to the 
middle of June. A smaller number 
of this second run die after spawning 
than of the kelt grilse. These kelts 
return during the autumn, winter, 
and spring, and most of them dis- 
appear by the end of April. Like 
the grilse kelt, they begin to return 
again about the middle of June; and 
many of them are of the same size 
as the grilse kelts—about 5 or 
6 lbs. They increase in weight as 
the season advances, and by Sep- 
tember some are caught up to 
12 and 14 lbs., according to the 
weight of the kelt that went down. 
Strange to relate, almost all the kelts 
that have been marked on the Tay 
and recaptured have been females. 
Particulars of some of these kelts 
that were marked and afterwards 
caught “in our “mets are? given
