The celebration of a midsummer festival by Mohammedan peoples is particularly remarkable, because the Mohammedan calendar, being purely lunar and uncorrected by intercalation, necessarily takes no note of festivals which occupy fixed points in the solar year; all strictly Mohammedan feasts, being pinned to the moon, slide gradually with that luminary through the whole period of the earth's revolution about the sun. This fact of itself seems to prove that among the Mohammedan peoples of Northern Africa, as among the Christian peoples of Europe, the midsummer festival is quite independent of the religion which the people publicly profess, and is a relic of a far older paganism. There are, indeed, independent grounds for thinking that the Arabs enjoyed the advantage of a comparatively well-regulated solar year before the prophet of God saddled them with the absurdity and inconvenience of a purely lunar calendar.[557] Be that as it may, it is notable that some Mohammedan people of North Africa kindle fires and bathe in water at the movable New Year of their lunar calendar instead of at the fixed Midsummer of the solar year; while others again practise these observances at both seasons. New Year's Day, on which the rites are celebrated, is called _Ashur_; it is the tenth day of Moharram, the first month of the Mohammedan calendar. On that day bonfires are kindled in Tunis and also at Merrakech and among some tribes of the neighbourhood.[558] At Demnat, in the Great Atlas mountains, people kindle a large bonfire on New Year's Eve and leap to and fro over the flames, uttering words which imply that by these leaps they think to purify themselves from all kinds of evil. At Aglu, in the province of Sus, the fire is lighted at three different points by an unmarried girl, and when it has died down the young men leap over the glowing embers, saying, "We shook on you, O Lady Ashur, fleas, and lice, and the illnesses of the heart, as also those of the bones; we shall pass through you again next year and the following years with safety and health." Both at Aglu and Glawi, in the Great Atlas, smaller fires are also kindled, over which the animals are driven. At Demnat girls who wish to marry wash themselves in water which has been boiled over the New Year fire; and in Dukkala people use the ashes of that fire to rub sore eyes with. New Year fires appear to be commonly kindled among the Berbers who inhabit the western portion of the Great Atlas, and also among the Arabic-speaking tribes of the plains; but Dr. Westermarck found no traces of such fires among the Arabic-speaking mountaineers of Northern Morocco and the Berbers of the Rif province. Further, it should be observed that water ceremonies like those which are practised at Midsummer are very commonly observed in Morocco at the New Year, that is, on the tenth day of the first month. On the morning of that day (_Ashur_) all water or, according to some people, only spring water is
