Will. A little farther I saw a man in a boat who was catching eels in an odd way. He had a long pole with broad iron prongs at the end, just like Neptune’s trident, only there were five instead of three. This he pushed straight down among the mud in the deepest parts of the river, and fetched up the eels sticking between the prongs.

Mr. An. I have seen this method. It is called spearing of eels.

Will. While I was looking at him, a heron came flying over my head, with his large flagging wings. He lit at the next turn of the river, and I crept softly behind the bank to watch his motions. He had waded into the water as far as his long legs would carry him, and was standing with his neck drawn in, looking intently on the stream. Presently, he darted his long bill as quick as lightning into the water, and drew out a fish, which he swallowed. I saw him catch another in the same manner. He then took alarm at some noise I made, and flew away slowly to a wood at some distance, where he settled.

Mr. An. Probably his nest was there, for herons build upon the loftiest trees they can find, and sometimes in society together, like rooks. Formerly, when these birds were valued for the amusement of hawking, many gentlemen had their heronries, and a few are still remaining.

Will. I think they are the largest wild birds we have.

Mr. An. They are of a great length and spread of wing, but their bodies are comparatively small.

Will. I then turned homeward across the meadows, where I stopped a while to look at a large flock of starlings which kept flying about at no great distance. I could not tell at first what to make of them; for they rose all together from the ground as thick as a swarm of bees, and formed themselves into a kind of black cloud, hovering over the field. After having a short round they settled again, and presently rose again in the same manner. I dare say there were hundreds of them.

Mr. An. Perhaps so, for in the fenny countries their flocks are so numerous as to break down whole acres of reeds by settling on them. This disposition of starlings to fly in close swarms was remarked even by Homer, who compares the foe flying from one of his heroes, to a cloud of stares retiring dismayed at the approach of the hawk.

Will. After I had left the meadows, I crossed the cornfields in the way to our house, and passed by a deep marl-pit. Looking into it, I saw in one of the sides a cluster of what I took to be shells; and upon going down, I picked up a clod of marl, which was quite full of them; but how sea-shells could get there I cannot imagine.

Mr. An. I do not wonder at your surprise, since many philosophers have been much perplexed to account for the same appearance. It is not uncommon to find great quantities of shells and relics of marine animals even in the bowels of high mountains, very remote from the sea. They are certainly proofs that the earth was once in a very different state from what it is at present; but in what manner, and how long ago these changes took place, can only be guessed at.
