Plainpalais. During this short voyage I saw the lightnings playing on
the summit of Mont Blanc in the most beautiful figures. The storm
appeared to approach rapidly; and, on landing, I ascended a low hill,
that I might observe its progress. It advanced; the heavens were
clouded, and I soon felt the rain coming slowly in large drops, but its
violence quickly increased.

I quitted my seat, and walked on, although the darkness and storm
increased every minute, and the thunder burst with a terrific crash over
my head. It was echoed from Salêve, the Juras, and the Alps of Savoy;
vivid flashes of lightning dazzled my eyes, illuminating the lake,
making it appear like a vast sheet of fire; then for an instant every
thing seemed of a pitchy darkness, until the eye recovered itself from
the preceding flash. The storm, as is often the case in Switzerland,
appeared at once in various parts of the heavens. The most violent storm
hung exactly north of the town, over that part of the lake which lies
between the promontory of Belrive and the village of Copêt. Another
storm enlightened Jura with faint flashes; and another darkened and
sometimes disclosed the Môle, a peaked mountain to the east of the lake.
