After all, the primary teacher's chief reliance for purposes of illustration must be natural objects. In this reliance we merely imitate the example of the great Teacher. The objects to be used will most often be suggested by the lesson text itself. A lily, a vine, seed, leaven, a door, a sickle, a cake, a cup, grass,--are not each of these objects at once associated in your mind with passages of Scripture? Hunt out the suggested objects, and simply hold them before the children as you talk about the lesson, and you will find them a wonderful assistance. A more difficult process is to discover illustrative objects when none are directly suggested in the text. In a temperance lesson, for instance, there may be no mention of the wine-cup, yet you will bring a glass, fill it with wine-colored water, and place in it slips of paper cut to resemble snakes. On each is written some fearful result of drinking alcoholic liquors; and after the children have drawn forth, with pincers, one after the other, and read what is written upon it, they will not soon forget how many evils come out of the wine-cup. You may be talking about the imprisonment of John the Baptist. Produce a pasteboard chain, painted black on one side. Each link tells in red letters one of the horrors of his imprisonment,--loneliness, fear, despair, and the like. Turn over the chain and show the underside gilded, the links reading, "More faith," "Near to God," "God's favor," "Courage," "Eternal reward." There was a bright side, after all. You are on the stumbling-block lesson, and you bring in some awkward, rough wooden blocks, on which you tack labels as the lesson proceeds: "A spiteful temper," "A gossiping tongue," "Envy," "Suspicion," "Swearing," "Treating to strong drink," "Playing marbles for 'keeps.'" You are teaching about the paralytic let down through the roof. It has not required many minutes, with pasteboard, scissors, and glue, to construct a dainty little model of an old-time Jewish house, outside stairs, inner court, overhanging court roof, and all. And how the little model illuminates the story! The jail in which Peter was imprisoned, the table around which the Last Supper was celebrated, the Tabernacle, the Temple,--from the many excellent pictures and descriptions obtainable, even quite ambitious models are possible of manufacture. And once made, they are aids and joys forever. The sand-map has become justly popular. It is easily formed, requiring only a shallow tray, some sharp, clean sand, pieces of looking-glass for lakes and seas, blue yarn for rivers, some rocks for mountains, wooden blocks for houses, dried moss for trees, little toy men, boats, horses, and such readily found apparatus.
