In order to correct the calendar an extra month or part of a month called Chotantsu is put in after Echon whenever necessary. The months being periods of the agricultural year the whole Lhota country is not in the same month at the same time. The inhabitants of a cold village where the crops are late may be struggling through Chikanika while those of a warm village are enjoying the peace and plenty of Ndrangtso. APPENDIX B MENSURATION There is no standard of weight in use throughout the tribe, but in every village there is kept a stone (ephwa) which is used in apportioning the shares of meat at feasts. The weight is generally nine to ten pounds. For trade a balance of the bismar type is used, notched to weigh in Indian seers and fractions of seers. The standard measure for rice is chukoluk, which is regarded as one man’s wage for a day and usually weighs about six pounds. The table would be as follows:— 2 chukolukruso = 1 chukoluk. 3 chukoluk = 1 sitsi. 1½ sitsi = 1 enokyak. Two baskets (etek) are regarded as going to one enokyak. The size of the baskets varies from village to village, and the buyer must accept the standard of the village from which he buys. Though nowadays Lhotas occasionally try to state distance in English miles, the real measure is by echen, the distance between one temporary granary and that at the next stage on the path up from the fields. It varies from village to village. On an easy slope it may be a mile and a half, on a steep slope it will be a mile or even less. The depth of water is either measured in echam (the height of a man) or eshi (kicks). That is to say, if a man having dived to the bottom of a pool has to kick his legs three times before he reaches the top, the pool is reckoned as three “kicks” deep. A tree is spoken of as so many phunchap (ladder-steps) high.
