How does Camara Laye use imagery in The Dark Child?

Examples of Imagery:

"At the first notes of the douga my father would arise and emit a cry in which happiness and triumph were equally mingled; and brandishing in his right hand the hammer that was the symbol of his profession and in his left a ram's horn filled with magic substances, he would dance the glorious dance." Chap. 2, p. 39.

"There was a rumor that Konden Diara sometimes pounced with fearsome claws on someone or other and carried him far away, far, far away into the depths of the bush; and then, days and days afterwards, months or even years later, quite by chance a huntsman might discover some whitened bones." Chap. 7, pp 101-102
