This grub is found, as it name indicates, at the roots of dockens: the
body of it is somewhat similar to a Maggot, it is a good bait for Trout
and Chub, and may be kept some time in a woollen bag containing fine
sand; fish will often take it when they refuse the worm, you may begin
to fish with it in February and continue to do so during the season.
Small May-fly hook and one No. 5 shot corn.
