Other stones worthy of notice now are, or have been found, at St Madoes and Dupplin, near Perth; at Kirriemuir, and elsewhere, in Forfar; and in some other places, chiefly along the north-eastern coast of the country. It must be remembered that the Reformation progressed much more slowly in the Highlands than in the Lowlands, so that we might naturally expect that the demolition of the crosses would not be carried out quite so thoroughly in the north as in the south. It was, however, in a southern town that we read of the last use, until recent times, of that ancient ceremony for Good Friday which our forefathers called "Creeping to the Cross." On May 8th, 1568, Grindal, then bishop of London, writes to Sir William Cecil, afterwards Lord Burleigh: "Evans, who is thought a man of more simplicity than the rest, hath reported (as I am credibly informed) that at Dunbar, on Good Friday, they saw certain persons go bare-foot and bare-legged to the church, to creep to the cross; if it be so the Church of Scotland will not be pure enough for our men." In spite of the abolition of the sign of the cross in the ceremonial of the church, and the destruction, so far as possible, of the material cross in its buildings, even Presbyterian Scotland could not discard the emblem of St. Andrew from among its national devices. The Covenanters marched across the Border in the Great Civil War, under a flag which bore that symbol; the white Cross of St. Andrew lay athwart its field, charged at the centre with the thistle, while in the spaces between the four members of the cross was the motto, "Covenants for Religion, Croune, and Kingdoms." Under the Commonwealth the royal arms, of course, dropt out of use, their place being taken by a shield, the first and fourth quarters of which were charged with St. George's Cross (for England), the second with St. Andrew's Cross (for Scotland), and the third with the Irish harp. [Illustration: COVENANTER'S FLAG.] Some few folk-customs, involving the use of this sign have also lived on in the northern kingdom. At Borera, for instance, is a Celtic cross, now overthrown; and whosoever wishes for rain has but to raise this, according to the local belief at one time, and he will obtain his desire. It used also to be customary in some parts of the country, when a bridegroom arrived at the church door ready for his wedding, to unfasten the shoe-string on his right foot and to draw a cross upon the doorpost. Such usages, however, seem to have been rarer in Scotland than in England.
