Deep Down, a Tale of the Cornish Mines

by R. M. Ballantyne

That Curtis was a man of no common force of character is obvious from the fact that, apart from the difficulties of the undertaking, he could not expect to derive any profit whatever from his labour for several years. As the work could only be carried on during the short period of time in which the rock was above water, and part of this brief period must necessarily be consumed each tide in pumping out the water in the excavation, it of course progressed slowly. Three summers were consumed in sinking the pump-shaft. After this a framework, or caisson, of stout timber and boards, was built round the mouth of the shaft, and rendered watertight with pitch and oakum. It rose to a height of about twelve feet above the surface of the sea, and was strengthened and supported by stout bars, or buttresses of timber. A platform was placed on the top, and a windlass, at which four men could work, was fixed thereon. This erection was connected with the shore by a stage or “wherry” erected on piles. The water was cleared out; the men went “underground,” and, with the sea rolling over their heads, and lashing wildly round the turret which was their only safeguard from terrible and instant destruction, they hewed daily from the submarine rock a considerable portion of tin.

These first workers, however, had committed an error in carrying on their operations too near the surface, so that water permeated freely through the rock, and the risk of the pressure above being too great, for it rendered the introduction of immense supporting timbers necessary. The water, too, forced its way through the shaft during the winter months, so that the regular working of the mine could not be carried on except in summer; nevertheless, this short interval was sufficient to enable the projector to raise so much ore that his mine got the reputation of being a profitable adventure, and it was wrought successfully for many years.

About the end of the century the depth of the pump-shaft was about four fathoms, and the roof had been cut away to the thinness of three feet in some places. Twelve men were employed for two hours at the windlass in hauling the water, while six others were “teaming” from the bottom into the pump. When sufficient water had been cleared away the men laboured at the rock for six hours—in all, eight hours at a time. The prolific nature of the mine may be gathered from the fact that in the space of six months ten men, working about one tenth of that time—less than three weeks—broke about 600 pounds worth of ore. During one summer 3,000 pounds worth of tin was raised!

A steam-engine was ultimately attached to the works, and the mine was sunk to a depth of sixteen fathoms, but the expense of working it at length became so great that it was abandoned—not, however, before ore to the amount of 70,000 pounds had been raised from under the sea!

At the time of our tale another effort had been made to work the Wherry Mine, and great expectations had been raised, but these expectations were being disappointed. Our unfortunate friend Mr Donnithorne was among the number of those who had cause to regret having ventured to invest in the undertaking, and it was to make inquiries in regard to certain unfavourable rumours touching the mine that Oliver Trembath had been sent to Penzance.

After inspecting Wherry Mine the two friends walked along the shore together, and Oliver explained the nature of the difficulties in which his uncle was involved.

“The fact is, Charlie,” he said, “an old fish-purchaser of Newlyn named Hitchin is one of the principal shareholders in this concern. He is as rich, they say, as Croesus, and if we could only prevail on him to be amiable the thing might be carried on for some time longer with every hope of a favourable result, for there can be no doubt whatever that there is plenty of tin in the mine yet, and the getting of it out is only a question of time and capital.”

“A pretty serious question—as most speculators find,” said Tregarthen, laughing; “you appear to think lightly of it.”

“Well, I don’t pretend to know much about such matters,” replied Oliver, “but whatever may be the truth of the case, old Hitchin refuses to come forward. He says that he is low in funds just now, which nobody seems to believe, and that he owes an immense sum of money to Jim Cuttance, the smuggler, for what, of course, he will not tell, but we can have no difficulty in guessing. He says that Cuttance is pressing him just now, and that, therefore, he cannot afford to advance anything on the mine. This being the case it must go down, and, if it does, one of the last few gleams of prosperity that remain to my poor uncle will have fluttered away. This must be prevented, if possible, and it is with that end in view that I purpose going to Newlyn this afternoon to see Hitchin and bring my persuasive powers to bear on him.”

“H’m, not of much use, I fear,” said Tregarthen. “Hitchin is a tough old rascal, with a hard heart and a miserly disposition. However, it may be worth while to make the attempt, for you have a very oily tongue, Oliver.”
