See Salmo, Ichthyology Index.

In angling for this fish the hook must be armed upon the shanks with a very narrow plate of lead, which should be slenderest at the bent of the hook, that the bait (which is to be a large grasshopper, the uppermost wing of which must be pulled off) may come over to it the more easily. At the point let there be a cod-bait in a continual motion. The jag-tail, which is a worm of a pale flesh-colour, with a yellow tag on its tail, is an excellent bait for the grayling in March and April.
