In the south wall, about twenty yards from the base, yawns the mouth of a huge cavern.
At that point the wall is so steep, and inclines forward to such a degree, that access to the cavern cannot be gained by means of a ladder. The robbers, however, had contrived a clever hoisting apparatus.
From the top of the opposite wall a mountain brook had once leaped into the defile, to continue its way over the rocky bed into the valley.
When the haidemaken first established themselves in the cavern, it happened frequently that they would be blockaded in their retreat by the nobles and their followers, who had pursued the predatory band to the defile.
At such times the robbers suffered greatly from the scarcity of fresh water, especially if they chanced to be out of wine. Therefore, they conceived the plan of conducting the brook from the opposing wall into the cavern through a stout oaken gutter, and the water at the same time served to turn a series of wheels. Over one of the wheels ran a stout iron chain, to which were securely attached several large baskets; and so skillfully was the apparatus manipulated that the entire band might be hoisted into, or let down from, the cavern in the short space of two hours. It was a most admirable contrivance for the robbers, but not so admirable for the dwellers in the valley. The intercepted brook now flowed into the cave, and, as the water did not fill the cave, the most natural conclusion was that it found an outlet through various subterranean fissures.
The turning of the water from its original channel caused Prince Siniarsky considerable inconvenience, in that all his saw-mills, flour-mills and leather factory were left without a motor; while the inhabitants of the surrounding hamlets, who were dependent on their looms for a livelihood, were compelled to remove to another region, because they now were unable to bleach the linen.
Still greater was the misfortune which had overtaken Count Potocky. He was the owner of extensive salt mines on the further side of the mountain, which contains an illimitable deposit of the saliferous substance. The haidemaken were unable to drink the water of the lakelet in the bottom of their cavern, because of its saline character.
After the course of the brook had been changed, the worthy Count Potocky discovered one day that innumerable springs of fresh water were bursting from his side of the mountain, and flooding his most profitable mines. If he attempted to obstruct the flow of water in one place it would break out in another.
At last the two magnates discovered the cause of the mischief, and determined to oust the thievish haidemaken from their retreat by fumigation. So long as the band confined their depredations to the trading caravans they might be tolerated; but, when they became insolent enough to interfere with the comfort and convenience of the magnates, it was high time to put a stop to their pestiferous conduct!
And so an expedition against the cavern was planned. Before it could be carried out the war against the Transylvanians and Swedes broke out, and the noble gentlemen were compelled to march with their followers toward the invaders; but when hostilities ceased and the succoring Tartars had returned home, a formal blockade of the robbers was constituted.
