The great advantage the fly fisher must derive from a knowledge of dyeing his colours and hackles is obvious. It affords amusement to the enthusiastic fisher to be acquainted with the various shades required for making his flies to suit the rivers, and the flies become valuable when made of good colours and hackles. Every hackle and colour that is used for making a salmon fly must be of the richest dye imaginable, that they may show brilliant and good to the fish's eye at the bottom of the water, and entice them to rise and take it at the top. The hackles must be taken from old cocks, both the neck and saddle ones, as they hold the dye best. Wool is not good for the fly, as it soaks the water, and is dull and heavy. Pig hair, that next the skin, with the stiff and coarse bristles picked and cleared away, and mohair, which is Spanish goat hair, a most beautiful brilliant substance for fly making when dyed well; white seal's fur, and furs of different kinds of a white colour. White hackles are best for yellows, oranges, gold colours, blues, greens, &c.; red hackles do best to dye claret, red, or fiery browns, olives, and cinnamon browns, &c., and black hackles for sooty olives, and tawny colours. When the angler sees a white old cock he should buy him to procure his hackles, or a black cock, a grey cock, and old red cocks of every hue, all of which are good for dyeing. These also must be washed in soap and hot water before being dyed, and the flue stripped off, tied in bunches (see the bunch of white hackles in the Plate of Feathers, ready for the dye) of proper sizes, and when about to be put into the dye-pot, wet them and the hair in hot water.

Provide a small crucible or earthen pot, glazed inside, with an earthen handle, to hold a quart of soft water, and before you put in your hackles or hair, wash them well, as I said before, in soap and hot water. The five principal colours to work upon are blue, red, yellow, brown, and black. From the combination of two or more of these may be produced every shade required, from the lightest to the darkest, so that it only requires some practice, to know the different ingredients to use, to become a Dyer of Fishing Colours.
