The hole was found and stopped. Labour the went on until in February, 1882, Mr Walker had the pleasure of seeing Sir John Hawkshaw pass through the whole of the heading. But the whole of the difficulties were not yet numbered. On the 2nd December, 1882, a panic ensued amongst the workmen, and all scampered for their lives to the top of the shaft, the ponies joining in the disorder and confusion. Mr Walker saw the men when they reached the surface, and to his alarm they averred that the sea had again broken in. At once he descended the shaft, and he found that there was absolutely no cause for alarm. But it was characteristic of the deceased gentleman that he did not blame the men. To understand, he said, how easily a panic spreads it would be necessary oneself to be under a river a mile away from the shaft, confined in a narrow space, with rocks dropping or running with water all around, and only the light of a stray candle here and there, and with all this the most recent extraordinary sounds that ever greeted the ears of the mortal man. But though he did not blame the men he had a bad quarter of an hour. On the 10th of October, 1883, there, however, was something more serious. Mr Walker and all with him had been congratulating themselves that things were all right, and had only left the tunnel an hour when the foreman drove up and said the great spring had broken in again. This subterranean reservoir had again the be conquered ; and again, later on, a great tidal wave flooded the working, imprisoning 83 men. To rescue these Mr Walker had a boat lowered down the shaft and launched in the tunnel.
