About four in the morning, Monday
-- The Field-Oven . -- A Meal on the Grass . -- A Night on the Ground . About four in the morning , Monday , the sun reappeared in the horizon ; the clouds had dispersed , and a cheery breeze refreshed the morning dawn . The earth , all redolent with fragrant exhalations , reappeared to the gaze of our travellers . The balloon , whirled about by opposing currents , had hardly budged from its place , and the doctor , letting the gas contract , descended so as to get a more northerly direction . For a long while his quest was fruitless ; the wind carried him toward the west until he came in sight of the famous Mountains of the Moon , which grouped themselves in a semicircle around the extremity of Lake Tanganayika ; their ridges , but slightly indented , stood out against the bluish horizon , so that they might have been mistaken for a natural fortification , not to be passed by the explorers of the centre of Africa .
