So it is and has been from the beginning. We can see the _results_ of changes of one thing into another but never just how the changing is done. While it is no longer believed that species were given a certain form in the beginning and that they have always kept that form, it is still true that each species comes into being from some unseen cause--"all of a sudden," as it were. Because species thus seem to vary of themselves, and not for any reason that we can see these changes are called "spontaneous variations." Always back of the material nature we can see is a nature that is not material; a part of nature that, like the mind of man, we can neither see nor hear nor feel nor know by any of our five senses. Some Unseen Power forms the baby plant out of the seed; some power changes the leaves hidden away in the bud into the petals of the flower. When the leaves gather to form the bud, like little hands playing "button, button, who's got the button," where do you suppose the flower is? It _isn't_. It has not yet begun to be. But soon, as if some magician had waved his wand and said "Presto! Change!" the pink petals begin to form there in the dark of the cup and, first thing we know, out steps Miss Blossom, all in her pink and gold like a princess dressed for a ball! But always hidden in a mystery these changes take place. We can peep into the growing bud as often as we like and we will never catch the fairies making the dress, nor the princess putting it on. We always see the thing after it is done! WONDERFUL ART BUT WHERE IS THE ARTIST?
