There are various kinds of light. Moonlight may be mistaken for the light of the sun by some creatures that have not seen the latter; also there are owls and bats which prefer it. Candles prove a source of destruction to ignorant moths. The lowliest germs, as we see, can emit a certain luminosity; even decaying matter shines. And so there are various kinds of light in the world of mind; but best of all is the sunlight. Twinkle, twinkle, little germ, How I wonder why you squirm, Down among my flesh and blood, Like a diamond in the mud. How doth the little busy bug Improve each shining hour By causing it to shine some more With half a candle-power. _Dr. What's-his-name_ LINNAEUS AND THE DIVINING-ROD: Contributed by P. F. Linnaeus in one of his works relates an experience he had in the finding of noble metals by means of the divining-rod, and does it in the simple good-humored way that marks all his writings and makes them such delightful reading. He says: The divining-rod is a curious contrivance, and people will have us believe that the rod can tell where metals are hidden. Now and again my secretary would take a twig of hazel forked evenly at one end and would amuse the company with it. This happened also at this place, one person concealing his silver snuff-box, another his watch, here and there in the bushes, and in most cases the secretary found them. Now I had never believed in the divining-rod and did not like to hear it mentioned. It provoked me that it should be recommended in this way, and I imagined that my friends and my secretary were in collusion to deceive the company. So going to a large field north of the barn, I cut out a piece of turf, placed my little purse in the hole, and covered it up so carefully that nobody could see the least trace of it. My own mark was a great ranunculus growing near the place, and there was no other tall flower in the whole field. When all was arranged I went back to the company, told them that I had concealed my purse in the field, and asked the secretary to find it with the help of his divining-rod. If he found it, then I would believe in the rod, so sure was I that no mortal but myself knew the place where the money was. The secretary was delighted with such an opportunity to make me think better of the rod which I used always to ridicule; and the company too were most anxious to watch this master-test. The secretary searched for a long while, a full hour at least, and my host and hostess and I had the pleasure of seeing the rod work in vain; and as we did not get the money back, the rod was held up to ridicule.
