4. rationality of women's life, which is centred in (though by no means confined to) the domestic domain. And within that domain, there is one resource which is critical: fuel supply. It could be said to be the key both to cropping choices and household food availability. Huss-Ashmore writes: "Because fuel is essential for processing almost all foods, it can be considered a critical resource for the maintenance of health and nutritional status. In Mokhotlong the type of fuel used, and the time spent to procure it, vary according to the seasonal availability of dung" (Huss-Ashmore 1982:156). The preferred fuel is compacted dung, readily available during the winter from the kraal close to the homestead, which, dried in uniform slabs, burn with the slow, even heat necessary for long cooking of dried grains and pulses. Women from kraal-less households have to purchase the dung or to manipulate kin relations to get it. When the cattle are moved in the summer to the high pastures, women must use horse and cattle dung, picked up from the fields and trails, which is less dense and takes more time to gather. Both sorts are kindled with resinous, woody shrubs which become scarcer as the summer passes but may be the only source of summer fuel if insufficient dung can be gathered. For a short period, kraal dung may be kindled with maize cobs as they are threshed in the winter. It is fuel availability rather than food availability which determines which foods are eaten at different seasons: "The supply of slow-cooking protein sources is not used equally throughout the year but is depleted during the cold season when appropriate fuels are available. During the summer the population relies heavily on wild vegetable protein sources, which require more time to locate and gather but which can be rapidly cooked" (Huss-Ashmore 1982:157).
