a roundabout way what they might have done directly with the greatest ease, and what, even when it is done, is of no use whatever for the purpose in hand.  A vast proportion of the labour which mankind has expended throughout the ages has been no better spent; it has been like the stone of Sisyphus eternally rolled up hill only to revolve eternally down again, or like the water poured for ever by the Danaids into broken pitchers which it could never fill.

[The belief that the need-fire cannot kindle if any other fire remains alight in the neighbourhood.]

The curious notion that the need-fire cannot kindle if any other fire remains alight in the neighbourhood seems to imply that fire is conceived as a unity which is broken up into fractions and consequently weakened in exact proportion to the number of places where it burns; hence in order to obtain it at full strength you must light it only at a single point, for then the flame will burst out with a concentrated energy derived from the tributary fires which burned on all the extinguished hearths of the country.  So in a modern city if all the gas were turned off simultaneously at all the burners but one, the flame would no doubt blaze at that one burner with a fierceness such as no single burner could shew when all are burning at the same time.  The analogy may help us to understand the process of reasoning which leads the peasantry to insist on the extinction of all common fires when the need-fire is about to be kindled.  Perhaps, too, it may partly explain that ceremonial extinction of all old fires on other occasions which is often required by custom as a preliminary to the lighting of a new and sacred fire.[740] We have seen that in the Highlands of Scotland all common fires were extinguished on the Eve of May-day as a preparation for kindling the Beltane bonfire by friction next morning;[741] and no doubt the reason for the extinction was the same as in the case of the need-fire.  Indeed we may assume with a fair degree of probability that the need-fire was the parent of the periodic fire-festivals; at first invoked only at irregular intervals to cure certain evils as they occurred, the powerful virtue of fire was afterwards employed at regular intervals to prevent the occurrence of the same evils as well as to remedy such as had actually arisen.

[The needfire among the Iroquois of North America.]

The need-fire of Europe has its parallel in a ceremony which used to be observed by the Iroquois Indians of North America.  “Formerly when an epidemic prevailed among the Iroquois despite the efforts to stay it, it was customary for the principal shaman to order the fires in every cabin to be extinguished and the ashes and cinders to be carefully removed; for it was believed that the pestilence was sent as a punishment for neglecting to rekindle ‘new fire,’ or because of the manner in which the fire then in use had been kindled.  So, after all the fires were out, two suitable logs of slippery
