We thought it Francesca's duty, as she was to be the wife of a Scottish minister of the Established Church, to look up Presbyterianism in Ireland whenever and wherever possible, with a view to discoursing learnedly about it in her letters,--though, as she confesses ingenuously, Ronald, in his, never so much as mentions Presbyterianism. As for ourselves, we determined to observe all theological differences between Protestants and Roman Catholics, but leave Presbyterianism to gang its ain gait. We had devoted hours--yes, days--in Edinburgh to the understanding of the subtle and technical barriers which separated the Free Kirkers and the United Presbyterians; and the first thing they did, after we had completely mastered the subject, was to unite. It is all very well for Salemina, who condenses her information and stows it away neatly; but we who have small storage room and inferior methods of packing must be as economical as possible in amassing facts. If we had been touring properly, of course we should have been going to the Giant's Causeway and the swinging Bridge at Carrick-a-rede; but propriety is the last thing we aim at in our itineraries. We were within worshipping distance of two rather important shrines in our literary pilgrimage; for we had met a very knowledgeable traveller at the Sorley Boy, and after a little chat with him had planned a day of surprises for the academic Miss Peabody. We proposed to halt at Port Stewart, lunch at Coleraine, sleep at Limavady; and meantime Salemina was to read all the books at her command, and guess, we hoped vainly, the why and wherefore of these stops.
