While thinking of these things Mr Musgrave was suddenly brought face to face with something so essentially modern that, prepared as he was for surprises in Mrs Chadwick's household, he was nevertheless taken completely aback. The first intimation of this extreme modernity rushed upon him disconcertingly, after the manner of a noisy herald preparing the way for some one of importance, in the shape of a very ugly and extraordinarily fierce-looking bull-dog. The bull-dog sprang out upon him from behind a wall and growled ferociously, showing his teeth, which is the custom of the well-bred bull, who cannot conceal them, as Mr Musgrave knew. Mr Musgrave, who disliked dogs, was nevertheless not so utterly foolish as to raise his stick, or otherwise show the alarm he felt; but he was very greatly relieved when a sharp, clear whistle called the bull-dog off and assured him that some one, who seemingly had authority, was at hand for his protection. Then it was that, looking up to trace the whistle to its source, he was confronted with the most astonishing sight he had ever beheld. Against the wall a long ladder leaned, and standing at the top of the ladder doing something apparently to a climbing rose-bush--or, to be exact, not doing anything to the climbing rose-bush at that moment, but looking down at himself--was a young woman. For a second John Musgrave thought it was a boy; during the next second it dawned upon his startled intelligence that this was no boy, but an exceedingly well-grown young woman--a young woman in male attire; that is to say, while the upper part of her was clothed in quite feminine fashion, the lower half--John Musgrave blushed as he grasped the horrible reality--was garbed in a man's overalls, a serviceable pair of loose-fitting blue trousers, buckled in at the waist with a workmanlike belt, in which was thrust pruning-knife, hammer, and other things necessary to a gardener at the top of a long ladder with no mate at the foot. "It is all right; he is quite gentle," the girl called down the ladder reassuringly to the astonished, upturned face of Mr Musgrave. She was, Mr Musgrave could not fail to observe, a very pretty girl, and she looked unquestionably well in the immodest get-up. Her hair, which was uncovered, was brown, and broke into curls at her temples; and a pair of smiling, darkly grey eyes gazed down at him amiably, with serene indifference to her embarrassing attire. Mr Musgrave imagined this male attire must be even more embarrassing to its wearer than it was to him to behold, in which he was quite mistaken. The girl was beautifully unconscious of anything in her appearance to attract comment. She wore trousers for use; and the serviceability of a thing explains and justifies its existence.
