"Not one of them. Threats and promises alike fail. There's safe to be an accident if they go down to-day, say the men; and they won't risk it. Bell had better not come in Ross's way whilst his present temper lasts," added Frank, as he began to screw a cork into a bottle. "I think Ross would knock him down." "Why Bell in particular?" "Because it is Bell who professes to have heard the Whistlers." "And none of the others?" cried the doctor. "I fancy not. Uncle Hugh, what _is_ the superstition?" added Frank. "What does it mean? I don't understand: and Ross, when I asked him, he turned away instead of answering me. Is it something especially ridiculous?" Dr. Raynor briefly replied. This superstition of the Seven Whistlers arose from certain sounds in the air. They were supposed by the miners, when heard--which was very rarely, indeed, in this neighbourhood--to foretell ill luck. Accident, death, all sorts of calamities, in fact, might be expected, according to the popular superstition, by those who had the misfortune to hear the sounds. Frank Raynor listened to the doctor's short explanation, a glow of amusement on his face. It sounded to him like a bit of absurd fun. "You don't believe in such nonsense, surely, Uncle Hugh!" Dr. Raynor had returned to the fire, and was gazing into it; some speculation, or perhaps recollection, or it might be doubt, in his grey eyes. "All my experience in regard to the Seven Whistlers is this, Frank--and you may make the most of it. Many years ago, when I was staying amongst the collieries in North Warwickshire, there arose a commotion one morning. The men did not want to go down the pits that day, giving as a reason that the Seven Whistlers had passed over the place during the night, and had been heard by many of them. I naturally inquired what the Seven Whistlers meant, never having heard of them, and received in reply the explanation I have now given you. But workmen were not so independent in those days, Frank, as they are in these; and the men were forced to go down the pits as usual." "And what came of it?" asked Frank. "Of the going down? This. An accident took place in the pit that same morning--through fire-damp, I think; and many of them never came up again alive." "How dreadful! But that could not have been the fault of the Seven Whistlers?" debated Frank. "My second and only other experience was at Trennach," continued Dr. Raynor, passing over Frank's comment. "About six years ago, some of the miners professed to have heard these sounds. That same day, as they were descending one of the shafts after dinner, an accident occurred to the machinery----" "And did damage," interrupted Frank, with increasing interest.
