Maphakathi nekhulu leshumi nesishiyagalolunye, abalimi abaningi baqala ukubuyisela indawo engenalutho futhi baya ngasentshonalanga emathafeni kanye nomngcele oseningizimu-ntshonalanga ngokulandelana. Ngenxa yokufuduka kwezolimo, abalimi baqaphela kakhulu ukushintsha imvelo. Ngaphambi kokuba izwe libuyiselwe, laligcwele amatshe nokuswelakala kwamanzi. Ngemva kokufuduka kwezolimo, ngenxa yokuntuleka kwamathuluzi ezolimo endawo kanye nobuchwepheshe bezolimo obuhambisanayo, izindawo eziningi azizange zihlalwe muntu, futhi zagcina zingabanikazi bazo. Endaweni entsha yokutshala, ukuze bavumelane nalesi simo, abalimi abaningi baqala ukumisa ucingo oluhlabayo ezindaweni zabo zokutshala.
Ngenxa yokuntuleka kwezinto ekubuyiselweni komhlaba ekuqaleni, emcabangweni wendabuko wabantu, udonga olwenziwe ngamatshe nezinkuni lungadlala indima yokuzivikela, engavikela imingcele yayo ekubhujisweni ngamanye amandla angaphandle futhi inyathelwe yizilwane, ngakho ukuqwashisa ukuvikela kunamandla.
Ngokushoda kwezinkuni namatshe, abantu bahlale befuna izindlela ezihlukile zothango lwendabuko ukuze bavikele izilimo zabo. Ngawo-1860 no-1870, abantu baqala ukutshala izitshalo ngameva njengocingo, kodwa ngomphumela omncane.
Ngenxa yokushoda kanye nentengo ephezulu yezitshalo, kanye nokuphazamiseka kokwakhiwa, zashiywa abantu. Ngenxa yokuntuleka kocingo, uhlelo lokubuyiselwa komhlaba lwalungasheleli kangako.
Ngo-1870, usilika obushelelezi wezinga eliphezulu wawutholakala ngobude obuhlukahlukene. AbakwaStockmen basebenzisa lezi zintambo ezibushelelezi ukuze bazungeze uthango, kodwa bathola ukuthi izinkukhu zazilokhu zingena ziphuma.
Khona-ke, ngo-1867, abasunguli ababili bazama ukwengeza imigogodla kusilika obushelelezi, kodwa akukho okwabonakala kuwusizo. Kuze kube ngu-1874, uMichael Kelly wasungula indlela ewusizo kakhulu yokwengeza ameva kusilika, wabe eseqala ukuyisebenzisa ngobuningi.
UJoseph Glidden wathola ukuthi kunentambo yokhuni endaweni encane evamile. Kunezinzipho zensimbi eziningi ezicijile ngakolunye uhlangothi lwentambo, futhi kuboshwe izintambo zensimbi ezibushelelezi ngakolunye uhlangothi. Lokhu kutholwa kwamjabulisa kakhulu. Kwenza futhi ukusungulwa kwakhe kubonakale ngendlela yocingo oluhlabayo. U-Glidden wabeka ama-spines emshinini wokusila kabhontshisi wekhofi wesikhashana, wabe esesonta ama-spines ngezikhathi ezithile ngocingo olubushelelezi futhi esonta enye intambo ezungeza imigogodla ukuze ibambe endaweni yayo.
I-Glidden yaziwa njengoyise wocingo oluhlabayo. Ngemva kokusungulwa kwakhe ngempumelelo, kusaqhubeka kuze kube namuhla ngokusungulwa okunegunya lobunikazi okungaphezu kuka-570 kocingo oluhlabayo. "Ingenye yezinto ezisunguliwe ezashintsha ubuso bomhlaba".
E-China, izimboni eziningi ezikhiqiza izintambo ezihlabayo zicubungula ngokuqondile izintambo zikathayela noma i-plastic-coated iron wire zibe ucingo oluhlabayo. Le ndlela yokuluka nokusonta ucingo oluhlabayo izothuthukisa ukusebenza kahle kokukhiqiza, kodwa ngezinye izikhathi kuba nobubi bokuthi ucingo oluhlabayo alulungisiwe ngokwanele.
Ngokuthuthukiswa kobuchwepheshe, abanye abakhiqizi manje baqala ukusebenzisa inqubo ethile yokufaka i-embossing, ukuze ubuso benduku yocingo bungabe busabushelelezi ngokuphelele, ngaleyo ndlela buthuthukise kakhulu umphumela wokuzinzisa iphimbo.
Ngameva alo abukhali, impilo ende yokusebenza, kanye nokufakwa okulula nokungenamkhawulo, ucingo oluhlabayo luye lwasetshenziswa kakhulu ezingadini, emafekthri, emajele nakwezinye izindawo ezidinga ukuhlukaniswa, futhi ziye zaqashelwa ngabantu.
Kuthiwani ngakho? Kazi uma umangale njengami ukuthi ucingo oluhlabayo lunomlando othakasela kangaka?
Uma unolwazi oluncane mayelana nocingo oluhlabayo, wamukelekile ukuxhumana nathi.
