Now Colonel Manners and Edward de Vaux, looking upon the privilege of walking arm-in-arm in its true light, might consider it with too much reverence to enter upon it lightly, and therefore not offer to exercise it towards their fair companions, till the steepness of the way and the openness of the country seemed to render it necessary for their convenience and protection. There might, indeed, be another reason, which was, that in issuing forth from the house, a little derangement in the natural order of things had taken place--some stray glove, or wandering stick, or something of the kind, had been forgotten, so as to throw out the order of the march; and Colonel Manners found himself walking beside Marian de Vaux, while De Vaux was at the elbow of his cousin Isadore. Colonel Manners, in agreeing to go out upon this expedition, had perfectly well understood the part he was held to play; and De Vaux had the most firm and implicit reliance upon his friend's tact in the business; so that by a tacit convention it was arranged between them, that the long ramble which Marian had promised to take with her lover was to be as completely solitary and agreeable as if they had not a friend or relation upon the face of the earth. But the derangement which had taken place in the position of the forces of course rendered a counter movement on the part of De Vaux and his friend necessary; and yet, as the walk they followed was narrow, and did not admit of the advance of more than two abreast, the desired evolution could not be performed without rendering the object unpleasantly obvious, till some little accident came to their aid. Colonel Manners, however, had been out in the morning, as we have already seen, to reconnoitre the ground; and as soon as he saw the difficulty, he instantly laid out the plan of the evolutions, and fixed upon the exact position, walking on still by the side of Marian de Vaux, and talking of _les mouches qui volent_.
