When the missionary Jerome of Prague was persuading the heathen Lithuanians to fell their sacred groves, a multitude of women besought the Prince of Lithuania to stop him, saying that with the woods he was destroying the house of god from which they had been wont to get rain and sunshine. The Mundaris in Assam think that if a tree in the sacred grove is felled the sylvan gods evince their displeasure by withholding rain. In order to procure rain the inhabitants of Monyo, a village in the Sagaing district of Upper Burma, chose the largest tamarind-tree near the village and named it the haunt of the spirit (nat) who controls the rain. Then they offered bread, coco-nuts, plantains, and fowls to the guardian spirit of the village and to the spirit who gives rain, and they prayed, O Lord nat have pity on us poor mortals, and stay not the rain. Inasmuch as our offering is given ungrudgingly, let the rain fall day and night. Afterwards libations were made in honour of the spirit of the tamarind-tree; and still later three elderly women, dressed in fine clothes and wearing necklaces and earrings, sang the Rain Song.
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.
