Of the Mongol physical characters the Lapp still retains the round low skull (index 83), the prominent cheek-bones, somewhat flat features, and ungainly figure. The temperament, also, is still perhaps more Asiatic than European, although since the eighteenth century they have been Christians--Lutherans in Scandinavia, Orthodox in Russia. In pagan times Shamanism had nowhere acquired a greater development than among the Lapps. A great feature of the system were the "rune-trees," made of pine or birch bark, inscribed with figures of gods, men, or animals, which were consulted on all important occasions, and their mysterious signs interpreted by the Shamans. Even foreign potentates hearkened to the voice of these renowned magicians, and in England the expression "Lapland witches" became proverbial, although it appears that there never were any witches, but only wizards, in Lapland. Such rites have long ceased to be practised, although some of the crude ideas of a material after-life still linger on. Money and other treasures are often buried or hid away, the owners dying without revealing the secret, either through forgetfulness, or more probably of set purpose in the hope of thus making provision for the other world. Amongst the kindred Samoyeds, despite their Russian orthodoxy, the old pagan beliefs enjoy a still more vigorous existence. "As long as things go well with him, he is a Christian; but should his reindeer die, or other catastrophe happen, he immediately returns to his old god _Num_ or _Chaddi_.... He conducts his heathen services by night and in secret, and carefully screens from sight any image of Chaddi[725]." Jackson noticed several instances of this compromise between the old and the new, such as the wooden cross supplemented on the Samoyed graves by an overturned sledge to convey the dead safely over the snows of the under-world, and the rings of stones, within which the human sacrifices were perhaps formerly offered to propitiate Chaddi; and although these things have ceased, "it is only a few years ago that a Samoyad living on Novaia Zemlia sacrificed a young girl[726]."
