Maitiro:

Idzi ndidzo shiri dzinobatana dzinowanikwa mumapoka maduku uye mapeji-kati, kunyange zvikafu zvikurusa zvemadhora 1 000 kana kupfuura zvakave zvichiratidzwa.

Dhizha-dumbu rine ruzha-madhanki anokwirira mumiti, kazhinji pamusoro pemvura, uye achatsvaira usiku, kudana uye kuridza nziyo sezvavanenge vachienda kunzvimbo dzakanaka. Vanodya nyore nyore pasi, uye kana vari mumvura isina kudzika, vachamira kusvika kune dabble nokuda kwezvinomera uye mbeu.

Kubereka:

Aya madhavha ari mumwe chete uye mudzimai kune hupenyu . Mukadzi wacho anowanzosarudza chivako chekuvakira, kunyange pane zviduku zvishoma zvekugadzira uye mazai machena akaiswa zvakananga pasi peganda. Nzvimbo dzomukati dzinowanzoita mamita 8 kusvika kumusoro kwevhu mumiti yakafa kana kuti mabhokisi ekudzvara, kunyange dai mabata aya dzimwe nguva ari dendere pasi pasi nechisimba chemafuro kana masora.

Apo 12-16 mazai anowanikwa kune imwe chete yemukomana , vatema-belly-mbira-mbira vanoita mazai evha uye kusvika mazana mazai anokwanisa kuwanika mumasango evanhu, kunyange maawa mashomanana eaya achaputika zvakanaka.

Vose vaviri vabereki vanogovera kugoverwa mabasa kwemazuva makumi maviri nemakumi maviri nemashanu, uye madhongi ezvakaitika kare anokwanisa kubva mudendere mushure meawa makumi mana mushure mekuvhara. Vabereki vaviri vanotungamirira uye vanochengetedza vana vavo kwemazuva 140-150. Nemhaka yenguva refu yekuchengetedza, imwe mhuri inowanikwa gore negore yakawanda, kunyange mumatunhu ekudengenyeka, mabata aya anogona kusimudza vana vaviri vana gore negore.
