Chapter 5. The Magical Control of the Weather.
Section 2. The Magical Control of Rain.
The intimate association of frogs and toads with water has earned for these creatures a widespread reputation as custodians of rain; and hence they often play a part in charms designed to draw needed showers from the sky. Some of the Indians of the Orinoco held the toad to be the god or lord of the waters, and for that reason feared to kill the creature. They have been known to keep frogs under a pot and to beat them with rods when there was a drought. It is said that the Aymara Indians often make little images of frogs and other aquatic animals and place them on the tops of the hills as a means of bringing down rain. The Thompson Indians of British Columbia and some people in Europe think that to kill a frog will cause rain to fall. In order to procure rain people of low caste in the Central Provinces of India will tie a frog to a rod covered with green leaves and branches of the nîm tree (Azadirachta Indica) and carry it from door to door singing:
“Send soon, O frog, the jewel of water!
And ripen the wheat and millet in the field.” 18
The Kapus or Reddis are a large caste of cultivators and landowners in the Madras Presidency. When rain fails, women of the caste will catch a frog and tie it alive to a new winnowing fan made of bamboo. On this fan they spread a few margosa leaves and go from door to door singing, “Lady frog must have her bath. Oh! rain-god, give a little water for her at least.” While the Kapu women sing this song, the woman of the house pours water over the frog and gives an alms, convinced that by so doing she will soon bring rain down in torrents. 19
