Thai Rubbing from the East Wall of the Temple of Wat Po, Bangkok: Hanuman Attacked By Leech [seems to be reversed with 1960.4.20 in order of narrative]
Hermit Nart gets up before dawn and goes down to the pool to wash and prepare himself for meditation. Remembering the trouble his guest has given him during the night, he throws his stick into the pool and changes it into a leech. Chuckling to himself, he goes away. Hanuman is up with the lark. Down he goes to the pool and ducks his face under the water to give it a good wash. The leech fixes itself to his chin, and the Son of the Wind discovers that all his efforts to remove it are in vain. In a panic he rushes to the hermit, throws himself at his feet and implores the old man to have pity on him. Nart takes hold of the leech, mutters a spell and, presto there is the stick in his hand. He smiles down at Hanuman. "Let that be a lesson, my good monkey," he says.
Hanuman takes his leave of the hermit and flies off, somewhat chastened, to the city of Longka.
