Usizo lwehose

Ngokuqala, abantu babalayelela izicatshulwa zokugcina ezinamandla kwiqhakamshini lokuhlola ukusetyenziswa. Ngexesha elikhulu, ngendawo yesiXhenxe yase 1700, amabhali ababili Van Delgegin waseNedherlandi bazibuyelela i-canvas hose egcinwe ngokubanzi, okungatholakaliyo kakhulu ngazo izifundo zokuphepha eziphumayo ngesikhatsi selokhu. Ngoku kuhlanganisa, ngenkxaso yokuthi i-rubber yakhiwe kumgaqirha ophakathi komhlaba kunye nokusebenzela kwesiseko sesiqhakamshini saso, i-rubber hose ne-hose eyahlukileyo yamathebhu, njengemadolo amagalagala okanye amahlobo akhona. Kodwa, umoya wasekhono, umoya wohlanga olunyeleyo lomoya, 'ihhide lika hidrogen, lika oxijen, lika heliyem esilungaphandle kwehlangothi; igasoleli, ikerosini, isibhidiso, isikhwama noma amaxesha asebenza, ukuba i-hose liyityhaliselo, khona, ayithethi. Ngokushesha olunyeleyo, usuku lwakho nomsindo ukuze ulibizwe.

Ngoko ke, abantu babenza ngokulandelana kunye nezilungiselelo zezincwadi ezimbili, ziphinda ukuba zityeleyo kwezintsha, ukuba izandla nendawo yakhe yayibuyiswe amaxesha okufunekayo. Ngokureyiyo, uhlobo olunye kwezindlela zikhishwe njengomphoyiso wemfene, futhi ungenzi lokugcina umoya, lokugcina imfula elumgciweni, lokugcina umhlaba omncane nokugcina umbhongo. Ngoku kusithathwa iindlela yamandla engenziweyo yokusebenza komphoyiso wezindlela.
