How does Gerald Durrell use imagery in My Family and Other Animals?

Imagery:

“Each day had a tranquility a timelessness about it so that you wished it would never end. But then the dark skin of the night would peel off and there would be a fresh day waiting for us glossy and colorful as a child's transfer and with the same tinge of unreality.”

“Tea would arrive, the cakes squatting on cushions of cream, toast in a melting shawl of butter, cups agleam and a faint wisp of steam rising from the teapot shawl.”

“The gold and scarlet leaves that littered the countryside in great drifts whispered and chuckled among themselves, or took experimental runs from place to place, rolling like coloured hoops among the trees. It was as if they were practising something, preparing for something, and they would discuss it excitedly in rustly voices as they crowded round the tree trunks.”
