"'In the Bible we're told there was once a flood that covered all the world. At that time all the rocks were mud, and the different things that were drowned were buried in it, and there's a snake that was buried that way. There are lots of 'em, and other things besides, in the rocks and stones hereabouts.'
"'A snake! But where's his head?'
"'You must read the Bible, I tell 'ee, and then you'll find out why 'tis that some of the snakes in the rocks ain't got no heads. We're told there, that the seed of the woman shall bruise the serpent's head, that's how 'tis.'"
When in his sixteenth year William Pengelly lost his younger brother, and after that his mother would not suffer him to go to sea. Some years were spent at Looe in self-education.
While still quite young he was induced by a relative of his mother to settle at Torquay, at that time a small place, but rapidly growing and attracting residents to it. Here he opened a small day-school on the Pestalozzian system, and was one of the first to introduce the use of the blackboard and chalk. The school opened with six scholars, but rapidly increased to about seventy.
It was now that scientific studies began to occupy Pengelly's attention, and above all, geology.
In 1837 he married Mary Anne Mudge, whose health was always delicate.
Little by little his renown as a geologist spread, and he did not confine himself to the deposits in Devonshire, but travelled to Scotland and elsewhere to examine the rocks, and to meet and consult with eminent scientists.
In 1846 his private pupils had grown so numerous that he was able to give up his school altogether and become a tutor of mathematics and the natural sciences. He tells a very amusing story of a visit made during holiday time to an old friend.
