Occasionally, however, intellectual efforts are made during sleep which would be difficult to surpass when awake. It is said that Condillac often brought to a conclusion in his dreams, reasonings on which he had been employed during the day; and that Franklin believed that he had been often instructed in his dreams concerning the issue of events which at that time occupied his mind. Coleridge composed from two to three hundred lines during a dream; the beautiful fragment of “Kubla Khan,” which was all he had committed to paper when he awoke, remaining as a specimen of that dream poem. The best thought points to the fact that dreams depend on natural causes. They generally take their rise and character from internal bodily impressions or from something in the preceding state of body or mind. They are, therefore, retrospective and resultant, instead of being prospective or prophetic. The latter opinion has, however, prevailed in all ages and among all nations, and hence the common practice of divination or prophesying by dreams, that is, interpreting them as indications of coming events. What Makes Our Teeth Chatter? When one is cold there is apt to be a spasm of shivering over which the brain does not seem to have any control. The spasm causes the muscles of the jaw to contract very quickly and as soon as they are contracted, they let the jaw fall again of its own weight. This occurring many times in rapid succession is what causes the teeth to chatter. There are two kinds of spasms, “clonic” and “tonic.” In the former, the muscles contract and relax alternately in very quick succession, producing an appearance of agitation. In the latter, the muscles contract in a steady and uniform manner, and remain contracted for a comparatively long time. The Story in a Honey-Comb[12] When one thinks of honey one instinctively closes the eyes and a mental picture of fruit trees laden with snowy bloom, of beautiful clover fields, of green forests in a setting quiet and peaceful, comes before the mind so realistic that the delicate perfume of the fragrant blossoms is almost perceptible and the memory of the musical hum of the little honeybee as she industriously flits from blossom to blossom, or wings her homeward way heavily laden with the delicious nectar, rests one’s jaded nerves. Into this picture fits closely the old bee master among his old-fashioned skeps, with the atmosphere of mystery that has so long been associated with the master and his bees that one is almost reluctant to think of the production of honey as a great commercial industry, employing great factories in the manufacture of beehives and other equipment necessary for the modern beekeeper that he may take full advantage of the wonderful and almost inconceivable industry of the honeybee in storing the golden nectar of the blossoms.
