from the ordinary marks of spear butts, for they are much smaller and deeper. This belief seems to show that the Potsos are regarded as coming in material form. The objects brought by the Potsos are generally believed to be taken back by them, but Niroyo village claim that some of their rice is from seed rice given to a ratsen by a Potso. A typical instance of this curious belief that these beings from another world sometimes visit the earth is the supposed visit of Potsos to the ratsen ’Nchemo of Illimyo in April 1919. ’Nchemo reported that two Potsos came with fourteen attendants and brought with them reeds, meaning sunny weather, part of a railway carriage (!), meaning elephants would give trouble, two loads of dark blue thread, meaning that someone would die “apotia,” and a broom, meaning that wind would damage the crops. The day after a village is visited by Potsos is kept as an emung both by the village to which they came and by its neighbours. Formerly if any village was visited in this way all Lhota villages, however distant, kept one day’s emung when they heard the news. Apart from special ceremonies performed to appease or gain the favour of the Rangsis, Sityingo and such-like godlings, it is to the Potsos that prayers are offered in sacrifices. Just as in England huge circular depressions in the hills are often called Devil’s Punchbowls, so the Lhota tends to assign big or curious things to the Potsos. For instance, the polished stone celts which are sometimes found in the fields are regarded as thunderbolts and are called “Potso’s axes” (Potsophü). The long flat seed-case, too, of a certain tree is called “Potso’s weaving-sword” (Potsotsitam). [127]
