I found the following story on Futility Closet's blog here. It was originally reported in The Times, July 12, 1882:
"Our Geneva Correspondent writes: — ‘A few days since two schoolmasters from Morzine, a Savoyard village near the Swiss frontier, made an excursion to the Col de Coux, not far from Champéry, in the Valais. As they were descending the mountain, late in the afternoon, they thought they heard cries of distress. After a long search they perceived a man holding on to a bush, or small tree, which had struck its roots into the face of the precipice.
"'As the precipice was nearly perpendicular and the man was some 1,200 ft. below them, and the foot of the precipice quite as far below him, they found it impossible to give the poor fellow any help. All they could do was to tell him to stay where he was — if he could — until they came back, and hurry off to Morzine for help. Though it was night when they arrived thither, a dozen bold mountaineers, equipped with ropes, started forthwith for the rescue. After a walk of 12 miles they reached the Col de la Golèse, but it being impossible to scale the rocks in the dark they remained there until the sun rose.
"'As soon as there was sufficient light they climbed by a roundabout path to the top of the precipice. The man was still holding on to the bush. Three of the rescue party, fastened together with cords, were then lowered to a ledge about 600 feet below. From this coign of vantage two of the three lowered the third to the bush. He found the man, who had been seated astride his precarious perch a day and a night, between life and death. It was a wonder how he had been able to hold on so long, for besides suffering from hunger and cold he had been hurt in the fall from the height above.
"'He was a reserve man belonging to Saméons, on his way thither from Lausanne, where he had been working, to be present at a muster. Losing his way on the mountains between Thonon and Saméons, he had missed his footing and rolled over the precipice. He had the presence of mind to cling to the bush, which broke his fall, but if the two schoolmasters had not heard his cries he must have perished miserably. Hoisting him to the top of the precipice was a difficult and perilous undertaking, but it was safely accomplished. None of the man’s hurts were dangerous, and after a long rest and a hearty meal or two he was pronounced fit to continue his journey and report himself at the muster.'"
