LLANSTADWELL (LLAN-STUDWAL), a parish, in the hundred of RHOS, union of PEMBROKE and county of PEMBROKE, SOUTH WALLS, 3 miles (E. by S.) from Milford; containing 833 inhabitants. This wish, which is situated on the northern shore of Milford Haven, comprises a considerable tract of fertile and well-cultivated land, with some portions of hilly ground, which, from its steepness, is but ill adapted to repay the expense and labour of cultivation. Still the agriculture is not indifferent; though there are few farmers of much capital, and others display little inclination to adopt the English aye- term. A visible improvement has recently taken place in the general roads, but they are yet far from good, which is the more to be regretted, as the conmunication between the adjacent towns of Haverfordwett, Milford, and Pembroke Dock is on the increase. Owing to the contiguity of the Royal yard at the last place, which is immediately opposite the parish on the other side of the river, the population has been very considerably augmented of late years. The rateable annual value has been returned at £3020. At Nayland, situated within the limits of the parish, it was once in contemplation to construct a dock-yard, for ,which purpose some lands in the vicinity were purchased, on both sides of the harbour, on which to erect works for its security and defence. Considerable Foogress has been made in the erection of one of the fortresses on the opposite side of the barren, but upon the death of the late Sir John Philipps, father of the late Lord Milford, who was the principal promoter of the design, the plan was abandoned, after two ships of war only had been built, the " Prince of Wales," of seventy-four guns, and the " Milford" frigate. The surrounding scenery is varied, combining the fine expanse of water in the haven on the south, and the spacious open channel on the west, with extensive tracts of richly cultivated country on the north and east. In the vicinity are several good houses, of which there are within the parish, Jordanston, Haysten, and Newton, a dilapidated old house on a valuable estate. The living is a discharged vicarage, rated in the kings books at £7. 17., endowed wish £200 royal bounty, and £200 parliamentary grant, and in the patronage of the Rev. A. Crymes: two-thirds of the great and small tithes are impropriate, and the remaining third belongs to the vicar, now commuted into a rent-charge of £110, of which lOs. are in lieu of Easter offerings; and there is a glebe of 7f acres, valued at £10 per annum. The church, dedicated to St. Tudwal, is an ancient structure in good repair, pleasantly situated on the margin of the haven, in the southern part of the parish. There is a place of worship for Wesleyan Methodists: about 25 children are instructed in two day schools at the expense of their parents; and there is a Sunday school, in which 40 males and females are taught gratuitously. A munificent bequest was made by the late Richard Mathias, of Hayston, Esq., of all his personal effects, amounting to nearly £1900, for founding and endowing a charity school, wherein the poor children of this, and the adjoining parish of Rhosmarket, were to be educated, the clergymen of both places for the time being to be trustees; but, owing to law expenses, the fund has been reduced to about £1200, which is appropriated according to the intention of the donor. Some remains of two ancient British encampments, comprising each an area of about one acre, are visible; one situated at the north-eastern extremity of the parish, nearly opposite the village of Rhelsmarket, and the other at its south-western extremity, on a point on the shore of Milford Haven.
