Fod cooking seeds, Karana "wove a tight basket of fine reeds...dried (it) in the sun...gathered lumps of pitch...softened them over the fire, and rubbed them on the inside of the basket so that it would hold water".  She then could heat small stones and drop them into a mixture of water and seeds in the basket to make gruel (Chapter 12).

For a fire, Karana hollowed out a place in the floor of her house and lined it with rocks.  She built her fire there, and to save work she covered the embers of her fire with ashes each night so that the next night all she would have to do is remove the ashes and blow on the embers to start up her fire again (Chapter 12).
