only in the cold liquid. When of the required tint, steep 

 the line in alum- water for a few minutes. 



8 thy The following is an admirable recipe, but require* 

 the greatest caution. Ten drops of aqua-fortis should be 

 dropped on a piece of copper, and left in a cup, to corrode 

 so long as it throws up any bubbles ; to these add cold 

 v, ater sufficient to dilute the mixture to a fine pale bluish 

 green : in this steep your line for about half a minute, or 

 more, and you will have an excellent water colour, which 

 at the same time takes oft* the gloss from the gut. If your 

 line be steeped previously, for about five minutes, in alum- 

 water, it will in some measure prevent the acid of the 

 mixture from penetrating so deeply, as to endanger its 

 being in any degree weakened. 



()fhj I have found common walnut catsup to give a 

 good colour to gut, steeped in it for half an hour, or more ; 

 but this tint is apt to fade : however, as it is so easily re* 

 newed, and is peculiarly excellent, I should recommend 

 its being adopted. 



Observe, by a good colour, I mean that which, in the 

 common run of angling, corresponds with the colour of 

 the water, and renders the line less visible : for it should 

 be particularly noticed, that we often find the sides of a 

 Stream of one colour, while the middle, or the current, 

 is quite of another hue ; and where several waters join, 

 we rarely see them all of the saine transparency, or of 

 the same tint. 



Some waters, owing to mineral impurities, will tinge 

 the line of their own colour, so as never after to change j 

 a fortunate circumstance for those who continue to angle 

 m jsfQch streams. J have had a line so completely stained
