ABSTRACT
Probably every household in Umor produces some surplus which is disposed of by sale. But the variations in the amounts are as great as the means of disposing of them are various and some analysis is necessary before an attempt can be made to assess the importance of exchange production within the households or to estimate the amounts of cash income that are secured. The numbers of livestock kept are in general so small that no substantial addition to income either by direct consumption or through sales is derived from this source. The returns from palm-oil and kernel production are, however, more considerable and are by far the largest single source of cash income. The yam consumption following the harvest and during the digging of new yams is correspondingly higher than is suggested by the average daily estimates given above. Money is also needed to meet other demands outside the direct household consumption.
