at all. The male par will spawn, or, as I mean, have 
milt the first year of its existence.” “I have seen smolt go to 
sea in shoals. I wont swear that I ever saw par going down 
with them.” “Par sometimes remain more than a year in the 
river after they are hatched. They then become smolts with a 
silvery skin, and in that state descend to the sea. When a 
smolt is stripped of its scales, it is a par below” (Jamus 
Marure). “The marks of a par are finger marks. The number 
of marks vary. I have found eleven, and I have found sixteen. 
The pars thus observed were of the same ages. The number of 
marks does not depend on the size. I never saw par with 
fewer than eleven. I have never seen par taken from any river 
but the Tay.” ‘The par of the trout has the dead fin orange ; 
the rudder fin is white at the bottom and yellow at the top. 
They have not so many par marks as the par. I do not think 
they have ever more than six marks” (PereR Marsuatt). 
«‘ There is not a pool or stream on the Teith where par are not 
(I confine myself to smolts). Every pool at a certain time has 
par. It is my opinion that pars are the fry of salmon. They 
assume the silvery scale when they go down the river. I 
have seen kelts taking on the same silvery coat at repeated 
times, in the end of March and April, preparing to descend the 
river; but before this I have seen them of a different colour” 
(James GREENHORN). 
Of the 1854 salmon hatching at Siabedonnalde Mr Buisr 
reported “that the first of the fry that left the pond as smolts 
in 1855 was on the 19th of May; the last on the 7th of June. 
No more left that year. The first of the same brood which 
remained as par all last season assumed the smolt scales in 
August, 1856. The first division went off on the 28th of April, 
and the last on the 26th of May. In both years they went off 
daily in divisions from the first to the last day. About 1,300 
were marked in 1855, and several returned, as stated in my 
report. The number marked in 1856 was 300 with rings, and 
800 with cuts in the tail. Taking one in each hundred as 
marked it may be reckoned thus:—Left the pond in 1856, 
130,000; in 1856, 100,000; total, 230,000.” Although many
