Namakwaland Die wêreld lê oop en kaal in die snikhete son hittegolwe bewe op die horison dit maak skimme op die grens die skaap soek koelte onder pens. The world lies open and naked in the hot sun heat waves quiver on the horizon it makes shimmers on the border the sheep searches for shade under paunch Die koggelmander skarrel stywebeen oor skroeiende granietklip heen. Geen koeltebome hier – die aarde is plat – Skilpad soek maar bossie, ander graaf maar gat The lizard scurries stiff-legged over scorching granite rock No shade trees here – the earth is flat – Tortoise looks for a small bush, others dig a hole Die klippe lê asof soos kaiings uitgebraai maar onder – deur die sandjies toegewaai – lê fyne saad gesaai, van moederplant al lank gespeen wagtend – op die reën. The rocks lie as if they were pieces of roasted crackling But underneath – covered by windblown sand – fine seeds are sown from parent plant weaned for long in waiting - for the rain . xxi
Die vlakhaas spits sy oor hy het die donderweer gehoor skilpad loer ook uit sy dop. Wildsbok lig en draai sy kop – sy neusgat vleuel soos hy die reënlug snuif daar gaan ñ rilling deur sy lyf sy stert staan kuif. The rabbit lifts his ear he has heard the thunder tortoise also peaks out his shell The wild buck lifts and turns his head - his nose flares as he smells the rain-filled air a shiver goes through his body his tail stands rigid Die donderweerswolke maak ñ donker sluier en die voorwind dwarrel en kuier hier en daar, van wie weet waar kielie ñ graspol en ritsel ñ blaar. Die eerste druppels val met sware plof in die dorre verpoeierde stof – dit maak ñ wasem op die klip en laat die sandtjies dans en wip. Water drup van die klip se rand in die dorstige rooi-rooi sand. The thunderclouds make a dark slur and the fore-wind tornadoes and visits here and there, from who knows where a grass is tickling and a leaf scurrying. The first drops fall with heavily, explosively in the dull powdered dust - it makes a haze on the rock and makes the sand particles dance and whip Water drips from the rock’s edge in the thirsty red-red sand.
