The river, as represented on a map, or imaginedafter a survey of the vast district which composes its basin,appears emphatically the many-headed Tay ; and, inconsequence of its great feeders coming down like themain arteries on a half-moon-shaped leaf, it has lessinequality in its stream than occurs in either the Speyor any other of our Highland rivers. The variety ofits origin, too, affords such a compensation of rain asalways, except in seasons of extreme drought, to yield asufficient bulk and altitude of water for the occupyingof its path, and the beautifying of its landscape ; whilethe wide variety in the relative distance of its sources,prevents its floods, however high, from being as suddenas those of the Spey, the Aberdeenshire Dee, and someother upland streams. Yet, owing to the gradual butgreat extension of the system of draining, which is pro-secuted oil arable grounds and on reclaimable mosses FIRTH ©if fll

TAY, THE TEALING and moorlands, the river has become considerably lessequable than at a former period ; it swells, during greatfloods, to a magnitude which never in former daysbelonged to it; it subsides, during a continued drought,to a corresponding diminution of volume ; and, in itsordinary or mean state, it has very visibly lost some ofits ancient greatness and importance. Though averagelycharged at Perth, as we have seen, with 3640 cubic feetof water per second, it was reduced, in the course of thesummer of 1819, to 457 cubic feet, and at the close ofthe summer of 1835, to a still smaller volume. Much of the country which now forms the seaboardof the estuary, and especially the whole of the Carse ofGowrie, and the lower part of Strathtay, exhibit evidenceof having, at a comparatively recent period, lain underthe sea, and been gradually raised above its level bydepositions from the Tay. After the Carse of Gowriebecame dry land, too, the Tay seems, for a long series ofyears, to have
