Kodwa inzululwazi akafuni kulala. Izazinzulu ziye iindlela ezahlukeneyo ukhula ukunceda ekulweni nabo. Ukhula, Kakade ke, bafumana iindlela mechanical. Le elima, basinda, ukulinywa, yaye isandla-esusa. Zezolimo ayasebenza ujikelezo. Kwaye ezi ndlela ukuze ixesha elithile incede ukuphelisa zizityalo ezingafunekiyo, kodwa hayi ixesha elide. Noko ke, kukho indlela ephumelelayo ngakumbi - it imichiza.

Kule ndawo, inzululwazi iye phambili kude. Ngokomzekelo, esebenzisa "Isaqhwithi" ukhula.
