He began by climbing the Calton Hill. He remained at the summit quite a long time, constructing a rough bird's-eye plan of the streets and buildings below him; and having descended to earth, proceeded on a series of voyages of discovery. He regarded the exterior of Parliament House with intense interest, for he was a debater by instinct and upbringing. St Giles' he passed by without enthusiasm--he was a member of the Free Kirk--and St Mary's Cathedral struck him as being unduly magnificent to be the property of such a small and pernicious sect as the Episcopalians. The Post Office and other great buildings struck him dumb; and he hastened past the theatres with averted eyes, for he had it upon unimpeachable authority that the devil resided there. He knew no one in Edinburgh save Elspeth M'Kerrow. However, he made another friend--to wit, one Hector MacPherson, a gigantic Highland policeman, who controlled the traffic with incredible skill at a place where several ways met. The said Hector stood beneath the shadow of a great lamp-post, and whenever a vehicle drove past one side of him, Hector relentlessly called it back and made it go on the other. Their acquaintance began with the entire effacement of Robert's features by the palm of Hector's hand, which was suddenly extended across the thoroughfare for traffic-regulating purposes, with the result that Robert, who was plunged in thought at the time, ran his nose right into the centre of it. The ejaculation to which each gave vent at the moment of impact revealed to both that they were from the same part of the country, and thereafter Hector MacPherson became Robert's adviser-in-chief throughout his stay in Edinburgh. Indeed, Robert used Hector as the starting-point for all his excursions, and whenever he became hopelessly lost in the wilds of the Grassmarket or the purlieus of Morningside, he used to ask his way back to his mentor's pitch and make a fresh start. We shall hear of Hector again. The foolhardy feat of entering a shop Robert did not attempt until his very last day in Edinburgh, and then only because he was absolutely compelled to do so by the necessity of executing a commission for his sister Margaret--the purchase of half a yard of ribbon. It is true that the same ribbon could have been obtained at home from Malcolm M'Whiston or a travelling packman, but Margaret was determined to have it from Edinburgh; and she was particularly emphatic in her injunctions to Robert to see that the folk in the shop stuck a label on the parcel, "with their name printed on, and a picture of the shop and a'."
