Maji Matamu Chini ya Genge la Bahari

Sehemu ya mwisho ya ngazi ni tofauti. Mwamba unaacha kuwa mkavu. Unazidi kuwa wa giza na baridi chini ya miguu yake, na kuna harufu ya jiwe lililolowa, na mwanga unaopanda kutoka majini unarusha mistari inayosogea kwenye dari ya chini ya pango lililo mwishoni.

The last stretch of the staircase is different. The rock stops being dry. It goes darker and cooler under her feet, and there is a smell of wet stone, and the light coming up off the water throws moving lines across the ceiling of a low cave at the bottom.

Na pale, usawa wa bahari, maji ya chumvi yakiwa hatua chache tu, maji matamu yanatoka mwambani. Polly anayatia mdomo wake. Ni baridi na matamu na hayapaswi kabisa kuwa pale, na ndiyo sababu ya kila kitu kilicho juu yake.

And there, at the level of the sea, with salt water a few steps away, fresh water is coming out of the rock. Polly puts her beak to it. It is cold and it is sweet and it is entirely wrong, and it is the reason for everything above her.

Hivi ndivyo inavyofanya kazi. Ardhi iliyo juu ya genge ni mwamba wa chokaa, na mvua haitiririki juu ya chokaa kama inavyotiririka juu ya miamba mingine. Inazama. Inatafuta nyufa na kuzipanua na kusafiri kushuka kupitia ndani ya jiwe, na kwa kuwa maji matamu ni mepesi kuliko maji ya bahari yanaweza kufika hadi chini kabisa ya genge na kuwasili yakiwa bado matamu, kwenye mstari wa maji kabisa, kabla bahari haijapata nafasi ya kuchanganyika nayo.

It works like this. The land on top of the cliff is limestone, and rain does not run off limestone the way it runs off other rock. It sinks. It finds cracks and widens them and travels down through the inside of the stone, and because fresh water is lighter than sea water it can come all the way to the bottom of the cliff and arrive still fresh, right at the water line, before the sea gets a chance to mix with it.

Sasa ngazi zinaeleweka. Si askari, wala si usiku mmoja. Huenda walikuwa watawa, wakichonga kushuka kwa subira kwa miaka mingi kuelekea chemchemi waliyojua iko pale, kwa sababu mji ulio juu ya genge unaweza kuwa na kuta na minara na mandhari ya mlangobahari mzima na bado ukapoteza kila kitu kwa kukosa funda la maji.

So now the staircase makes sense. Not soldiers, and not one night. Monks, most likely, cutting patiently downward over years toward a spring they knew was there, because a town on top of a cliff can have walls and towers and a view over the whole strait and still lose everything for the want of a drink of water.
