Trolling with the live or dead minnow, or a small spoon with a single hook, is a very successful method on lakes, ponds, and broad, still rivers. A greater length of line can be utilized in trolling, whereby the fish is not so apt to see the angler. More ground can also be covered than in any other style of fishing. The boat should be propelled slowly along the borders of rushes and weed patches, over shoals and gravelly banks, and near projecting points of the shore. Considerable care should be exercised to move as noiselessly as possible, avoiding splashing with the oars or paddle, or making any undue noise with the feet or otherwise in the boat, as such sounds are conveyed a long distance in so dense a medium as water. In trolling, the line may be lengthened to fifty yards, if necessary, though from twenty to thirty yards will usually be sufficient, especially when a good breeze is blowing. Bobbing for the large-mouth bass is much in vogue in the Gulf states, but is more often practised in Florida. The conventional "bob" is formed by tying a strip of deer's tail, with or without a piece of red flannel, around a triangle of hooks, the hairs completely investing the hooks. A single hook, however, answers fully as well or better. The hook is of large size, Nos. 3-0 to 5-0. The method of procedure is as follows: The boat is propelled by a single-bladed paddle, the paddler being seated in the stern. The boat is moved silently and cautiously, skirting the edges of water-lilies and bonnets, which grow thickly along the margin of the channels. The angler is seated in the bow with a very long cane rod, to which is affixed a short line of a few feet, not to exceed six. As the boat advances, the angler dances the bob as far ahead as possible. It is held a few inches or a foot above the water, into which it is "bobbed" at short intervals. Sometimes the bass leaps from the water to seize it. When hooked, the fish islanded without any ceremony and as soon as possible, keeping it meanwhile on the surface, to prevent its taking to the weeds. Bartram described bobbing as practised in Florida, for black-bass, nearly a century and a half ago.
