GASK-TRINITY, a parish, in the county of Perth, 2 miles (N.) from Auchterarder, and 4 (S. E.) from Crieff; containing 620 inhabitants. This parish is said to derive its name Gask, of Gaelic origin, from the peculiar nature of its surface, consisting almost entirely of braes and undulated ground: the distinctive prefix. Trinity, arose from the union of three districts, which constitute the present parish. Trinity-Gask is chiefly situated on the north bank of the river Earn, in the picturesque strath to which that river gives name; and is about five miles in length, and three in breadth. Its surface is pleasingly varied, containing but few tracts of level land; and the scenery is enlivened by the windings of the Earn, which flows from west to east, displaying much beauty in the natural wood and thriving plantations with which its banks are crowned. The soil, greatly differing in various parts, has in some been much improved by draining, and by the construction of embankments to protect the lower lands from the occasional overflowings of the Earn; and through the improvement that has taken place in the system of agriculture, a considerable portion of barren land has been reclaimed and brought into profitable cultivation. Of the whole number of acres in the parish, nearly 4300 are arable, and 1000 in woods and plantations; the remainder is chiefly moorland and waste, and it is supposed that about '2000 acres may be rendered arable, when the measures at present in contemplation for that purpose shall be carried out. The river abounds with various kinds of fish, the principal of which are salmon, trout, perch, and pike; but the quantity of salmon has greatly diminished since the use of stake-nets was introduced in the Tay. The crops raised in the parish are, grain of all kinds, potatoes, and turnips. Bone-dust and lime are used, but on account of the expense of bringing those articles from a great distance, the quantity is not adequate to the wants of the soil. Great attention is paid to the rearing of cattle; the short-horned breed was introduced by Lord Strathallan, and is found to answer well: the sheep, which are very limited in numbers, are chiefly of the Leicestershire breed. The farm-buildings are substantial, and on all the large farms are threshing-mills, several of which are driven by water. There are also corn-mills in various parts. The annual value of real property in the parish is £4700. The oldest of the woods are of Scotch fir; and the plantations of more modern date are principally spruce, larch, oak, and beech, all of which, under judicious management, are in a thriving state. In this parish the substrata are chiefly sandstone and whinstone, of which there are several varieties, and occasionally a gray stone, of great compactness, containing a portion of copper, but not sufficient in quantity to repay the cost of working it. Both the sandstone and whinstone are quarried for building purposes, and for the roads; but the stone is of inferior quality. Millearne, a seat in the parish, is a spacious mansion in the later English style, beautifully situated in grounds laid out with great taste, and forming a conspicuous feature in the landscape. Colquhalzie is a handsome mansion finely seated on the south bank of the Earn, and commanding some highly interesting views. Facility of intercourse with the neighbouring towns is afforded by good roads; a ferry-boat plies across the river, and at Kinkell is a bridge of four arches, built by subscription in 1793, and kept in excellent repair. An agricultural society has been established in the parish, for the promotion of husbandry, by the distribution of prizes to the successful candidates in plough- ing matches. Ecclesiastically the parish is within the bounds of the presbytery of Auchterarder, synod of Perth and Stirling; patron, the Earl of KinnouU. The stipend of the incumbent varies from £190 to £"270; the manse is a commodious residence, and the glebe comprises fourteen acres and a half of profitable land, with about ten acres of wood. Trinity-Gask church is adapted for a congregation of about 350 persons, but is inconveniently situated. There is a place of worship for the United Presbyterian Church. The parochial school affords a useful education; the master has the maximum salary, and the fees average about £12 per annum. The poor receive the interest of a bequest of £80. Some remains exist of an ancient castle called Gascon Hall, of which, however, there are no authentic records; and a considerable portion of the Roman road leading to the camp at Ardoch is within the parish. A kistvaen, containing human bones and ashes, was found on the lands belonging to the Earl of Kinnoull; it consisted of four upright stones, with one lying horizontally on the top.
