Visiwa Tisa, Mabamba Matatu

Polly aliruka chini kando ya ufuo wa miamba myeusi ya volkano, ambapo mashamba ya kijani yalienea hadi ukingoni mwa jabali na ukungu ulitambaa taratibu juu ya vilima vilivyoviringana kuelekea bara. Hiki kilikuwa São Miguel, kikubwa kuliko vyote kati ya visiwa tisa vinavyounda visiwa vya Azores, kikiwa peke yake katikati ya Atlantiki ya Kaskazini. Harufu ya chumvi ilichanganyika na ile ya udongo wenye unyevu na majani yaliyokatwa, na mahali fulani chini jogoo aliwika kutoka shamba ambalo hakuliona bado.

Polly came in low over a coastline of black volcanic rock, where green fields ran right up to the cliff edge and mist slid slowly across rounded hills further inland. This was São Miguel, the largest of the nine islands that make up the Azores, sitting alone in the middle of the North Atlantic. Salt air mixed with the smell of wet earth and cut grass, and somewhere below a rooster called out from a farm she could not yet see.

Kisiwa chote kipo kwa sababu ya ufa ulio mbali chini ya sakafu ya bahari, mahali ambapo mabamba matatu makubwa yanayobeba mabara yanasagana taratibu. Amerika Kaskazini inavuta upande mmoja, Ulaya upande mwingine, na Afrika inasukuma kutoka kusini, na pale kingo hizo tatu zinapokutana, joto na shinikizo hutafuta njia ya kupanda kupitia nyufa za gamba la dunia. Kila kisiwa katika mnyororo huu kilijengwa kwa njia ile ile, mlipuko mmoja baada ya mwingine, kutokana na moto na mwamba unaopoa tu.

The whole island exists because of a seam far below the ocean floor, a place where three of the great plates that carry the continents grind slowly against each other. North America pulls one way, Europe another, and Africa presses in from the south, and where the three edges meet, heat and pressure find their way up through cracks in the crust. Every island in this chain was built the same way, one eruption at a time, out of nothing but fire and cooling rock.

Karibu kila shamba huko São Miguel limezungushiwa ua wa maua ya hydrangea, ya buluu na urujuani na wakati mwingine waridi hafifu, yaliyopandwa kwa wingi hivi kwamba yanaonekana kama yamechorwa juu ya mandhari. Wakulima walileta mimea hiyo kutoka Asia katika karne ya kumi na tisa ili tu kuweka mipaka kati ya malisho, bila kutegemea kwamba ingekuja kuwa alama ya kisiwa. Udongo wa volkano, wenye madini tele, huyafanya maua yake kuwa ya buluu iliyokolea kuliko ua hilo hilo linavyokua sehemu nyingine yoyote duniani.

Almost every field on São Miguel is edged by a hedge of hydrangeas, blue and violet and sometimes a soft pink, planted so thickly they look painted onto the landscape. Farmers brought the plants from Asia in the nineteenth century simply to mark the borders between pastures, never expecting them to become the island's signature. The volcanic soil, rich in minerals, turns their petals a deeper blue than the same flower grows almost anywhere else in the world.

Kuelekea ndani zaidi, vilima vya kijani vilipanda na kujikunja kuzunguka mabonde mapana na tulivu ambayo Polly hakuweza kuyaona kutoka pwani. Mvuke ulipanda kwa upole kutoka mahali fulani kati yao, nyuzi nyembamba nyeupe dhidi ya anga la kijivu, naye akaelekeza safari yake kwenye nyanda za juu kuona ni nini kilikuwa kikiutoa.

Further inland, the green hills rose and folded around wide, quiet basins that Polly could not see into from the coast. Steam rose faintly from somewhere among them, thin white threads against the grey sky, and she turned her flight toward the high ground to see what was making it.
