Cp. vaŋsa -- ghatikā "a kind of game" Divy 475), against Dial. i.9 "acrobatic feats by Caṇḍālas." Cp. J iv.390 in same passage. Franke (Dīgha trsln) has "bamboo -- tricks"; his conjecture as "vaŋsa -- dhamanaŋ," playing the bamboo pipe (cp. Miln 31: "vaŋsadhamaka"), as oldest reading is to be pointed out. <-> On vaŋsa in similes see J.P.T.S. 1907, 134.
