The Tavy is unhappily named, so is its brother the Taw--both being sons of Mother Cranmere--if it is true their names are derived the one from the Gaelic _tav_, the other from the Welsh _taw_. The root word is _tam_, which appears appropriately enough in Thames, and means placid and spreading. The Tavy and the Taw are anything but that. They are never placid, not even in the dog-days. They brawl more noisily than all the other rivers in Devon. Perhaps they were so named on the _lucus a non lucendo_ principle; because it is so obvious they are not placid. The river Tavy has a good deal of property. Wherever it winds it has bestowed its name. The family of Tavy is a very ancient one. It was rich and important once, possessing a number of rights, many valuable mines, much romance, to say nothing of towns abbeys, and castles; but, like most old families, it has decayed, and its property is not worth much now. It possesses Tavy Cleave; the villages of St. Peter and St. Mary (they were twins, exceedingly healthy in their youth, but growing feeble now); Mount Tavy, which is of no importance; Tavystoc, the fortified place upon the Tavy, which has been turned into Tavistock and has become famous, not for its Abbey, nor for its great men, but solely and simply for its Goose Fair; and Mary and Peter Tavy, who were not made of cob, or granite, or water, or tin, or any of those other things which made the fortune of the Tavy family, but were two simple animals of the human race, children of the river out of that portion of Dartmoor which it owns, two ignorant beings who took life seriously enough and were like the heather and gorse which surrounded them. Evolution has accomplished such marvels that Peter and Mary may possibly have been lineally descended from antediluvian heather and gorse; or perhaps Nature had intended them for heather and gorse, and while making them had come across a couple of shop-soiled souls which were not of much use, and had stirred them into the mixture which, after a certain treatment only to be explained by a good deal of medical dog-Latin, resulted in Mary and Peter being brought forth as divine images upon the edge of Tavy Cleave.
