14 SALMON AND TROUT. 
To tie a double slip knot: first make a single slip knot, a, and, 
before drawing close, pass the gut end, J, a second time round the 
central link, c,and then again through the 
az-¢ loop, a—when the knot will be like ‘a’ 
in the diagram of double slip knot. To 
complete it, pull the end of the gut, 6—gradually, and very tightly 
—straight away : in a line, that is, with the central link, ¢. 
The slip knot is also the best for attaching the casting line 
to flies with gut loops, and should be tied in the same manner 
as that described for a turn-down eyed hook. 
SINGLE SLIP KNOT ATTACHMENT TO GUT LOOP. 
The same knot, for both gut or metal loops, may also be pro- 
duced in another manner—when the loop is large enough—viz., by 
tying at the end af the casting line (separate from the hook) a 
‘noose, with a slip knot (drawn tight), and afterwards passing 
from above, through the loop or eye, the ‘apex’ of the noose thus 
formed. The noose is then opened out and passed upwards over 
the whole fly, ‘lasso-wise’; the knot is drawn to its place in the 
loop as already described, and the ‘slack’ taken in. 
There is a mode of attaching casting lines to gut-looped 
salmon flies very commonly employed on account of its 
facility of manipulation, and the saving of trouble and time in 
changing flies. In consists in tying a knot at the end of the 
gut, and then passing the knotted end first through the loop 
from below, and, after giving it one turn round under the loop, 
finally passing the knotted end under the central link, and 
drawing the latter tight. It is in fact a ‘jam knot’ plus the 
knot at the end of the line. Excellently well as this knot 
answers for hooks of the smaller sizes with eyes turned down, 
as hereafter described, it does not and never can make a
