Again, tree-spirits make the crops to grow. Amongst the Mundaris every village has its sacred grove, and "the grove deities are held responsible for the crops, and are especially honoured at all the great agricultural festivals." The negroes of the Gold Coast are in the habit of sacrificing at the foot of certain tall trees, and they think that if one of these were felled all the fruits of the earth would perish. The Gallas dance in couples round sacred trees, praying for a good harvest. Every couple consists of a man and woman, who are linked together by a stick, of which each holds one end. Under their arms they carry green corn or grass. Swedish peasants stick a leafy branch in each furrow of their corn-fields, believing that this will ensure an abundant crop. The same idea comes out in the German and French custom of the Harvest-May. This is a large branch or a whole tree, which is decked with ears of corn, brought home on the last waggon from the harvest-field, and fastened on the roof of the farmhouse or of the barn, where it remains for a year. Mannhardt has proved that this branch or tree embodies the tree-spirit conceived as the spirit of vegetation in general, whose vivifying and fructifying influence is thus brought to bear upon the corn in particular. Hence in Swabia the Harvest-May is fastened amongst the last stalks of corn left standing on the field; in other places it is planted on the corn-field and the last sheaf cut is attached to its trunk. Again, the tree-spirit makes the herds to multiply and blesses women with offspring. In Northern India the _Emblica officinalis_ is a sacred tree. On the eleventh of the month Phalgun (February) libations are poured at the foot of the tree, a red or yellow string is bound about the trunk, and prayers are offered to it for the fruitfulness of women, animals, and crops. Again, in Northern India the coco-nut is esteemed one of the most sacred fruits, and is called Sriphala, or the fruit of Sri, the goddess of prosperity. It is the symbol of fertility, and all through Upper India is kept in shrines and presented by the priests to women who desire to become mothers. In the town of Qua, near Old Calabar, there used to grow a palm-tree which ensured conception to any barren woman who ate a nut from its branches. In Europe the May-tree or May-pole is apparently supposed to possess similar powers over both women and cattle. Thus in some parts of Germany on the first of May the peasants set up May-trees or May-bushes at the doors of stables and byres, one for each horse and cow; this is thought to make the cows yield much milk. Of the Irish we are told that "they fancy a green bough of a tree, fastened on May-day against the house, will produce plenty of milk that summer."
