We shall not explore Portobello further, but turn to the left, and follow the road that runs parallel to the railway to Leith. On one side of us is the sea, breaking on a narrow, shingly beach; and beyond, there is nothing to stop the eye till it reaches the distant shores of Fife, but the rugged outline of Inchkeith, with its lines of fortification gleaming white in the sunlight. Before we have gone very far, we see a level crossing and a signal-box on the railway beside us; and, taking advantage of our privileges as pedestrians, we pass safely and unquestioned through the narrow posterns, while it might require some persuasion to get the heavy gates unlocked and opened for a carriage to enter them. We now find ourselves following a straight path leading across the flat green meadows, which stretch far away on either side, their expanse being only broken by narrow watercourses. With the level rays of the afternoon sun glancing over them, gilding the tips of the grass, and imparting an air of Dutch-like prosperity and peace, it comes upon one rather as a shock to be told that these quiet pastures are the great sewage farm of Edinburgh, an experiment on a large scale which has turned out successfully. We presently come to high walls, behind which stands the old house of Craigentinnie, long the inheritance of the Nisbets, a younger branch of the Nisbets of Dean. As we have already said, it was bought in the last century by the father of the late Mr. William Miller. The latter added greatly to the house, and built steep roofs and turrets in the style of a French château, which has altered it very much from the old Scotch house that originally stood there. We now come to the little village of Restalrig, or Lestalric, as it used always to be called. For centuries it was famous all over Scotland as the burial-place of the blessed virgin St. Triduana. "She is said," writes Dr. Laing, "to have come from Achaia in the 4th century in company with St. Regulus, and to have died at Restalrig in the year 510, in the reign of Eugenius III., the 8th of October being held as her festival day. Although no precise date can be assigned when a church or chapel was first erected and dedicated to this saint, whose bones for many centuries were held in high veneration, or when it first became the parish church of Leith, we can trace it back at least to the 12th century."[48] [48] _Collegiate Churches of Midlothian._ Bannatyne Club, 1861.
