What is wanted in the present state of Folk-lore, I here repeat, is collection from original sources, and material, that is from people and not merely from books. The critics we have--like the poor--always with us, and a century hence we shall doubtless have far better ones than those in whom we now rejoice--or sorrow. But material abides no time, and an immense quantity of it which is world-old perishes every day. For with general culture and intelligence we are killing all kinds of old faiths, with wonderful celerity. The time is near at hand when it will all be incredibly valuable, and then men will wish sorrowfully enough that there had been more collectors to accumulate and fewer critics to detract from their labours and to discourage them. For the collector must form his theory, or system great or small, good or bad, such as it is, in order to gather his facts; and then the theory is shattered by the critic and the collection made to appear ridiculous. And so collection ends. There is another very curious reflection which has been ever present to my mind while writing this work, and which the reader will do well carefully to think out for himself. It is that the very first efforts of the human mind towards the supernatural were gloomy, strange, and wild; they were of witchcraft and sorcery, dead bodies, defilement, deviltry, and dirt. Men soon came to believe in the virtue of the repetition of certain rhymes or spells in connection with dead men's bones, hands, and other horrors or "relics." To this day this old religion exists exactly as it did of yore, wherever men are ignorant, stupid, criminal, or corresponding to their prehistoric ancestors. I myself have seen a dead man's hand for sale in Venice. According to Dr. Block, says a writer in The St. James's Gazette, January 16, 1889, the corpse-candle superstition is still firmly enshrined among the tenets of thieves all over Europe. In reality, according to The Standard, we know little about the strange thoughts which agitate the minds of the criminal classes. Their creeds are legends. Most of them are the children and grandchildren of thieves who have been brought up from their youth in the densest ignorance, and who, constantly at war with society, seek the aid of those powers of darkness in the dread efficacy of which they have an unshaken confidence.
