Vermuyden had acquired, in his native country, some slight knowledge of alchymy, and he carried out with him not only mercury, aqua regia, and large melting pots, but also a divining rod, which, however, as was most likely the case, was not found to exhibit any virtue.

Vermuyden, however, was not to be laughed out of his superstitious notions, although his companions took every opportunity of turning his expectations into ridicule, but he found a very plausible excuse for the impotency of his divining rod in the discovery, that its qualities had all been dried up by the heat of the climate, and that, under every circumstance, it was not an instrument adapted to the country in which it was to be carried into use.

On one occasion, however, the virtue of the divining rod appeared suddenly to have returned, for his eyes were gladdened with the sight of a large mass of apparent gold; the delusion, however, soon vanished, for, on examination, it was found to be nothing more than common spar.

According to his report, the metal is never met with in low fertile and wooded spots, but always in naked and barren hills, embedded in a reddish earth.

At one place, after a labour of twenty days, he succeeded in extracting twelve pounds, and, at length, he asserts that he arrived at the mouth of the mine itself, and saw gold in such abundance, as surprised him with joy and admiration.
