That the air is fresh, the above statement sufficiently establishes.  That it is bracing, I argue from the fact that I find it impossible to open the shutters on the windward side of the house.  That it is healthy, I am also convinced, believing that there is no other force in Nature that could so buffet and ill-use a person without serious injury to him.  Let me offer an instance.  The path to my door crosses a slight eminence.  The unconscious visitor, a little exhausted by the ascent and the general effects of the gentle gales which he has faced in approaching my hospitable mansion, relaxes his efforts, smooths his brow, and approaches with a fascinating smile.  Rash and too confident man!  The wind delivers a succession of rapid blows, and he is thrown back.  He staggers up again, in the language of the P. R., “smiling and confident.”  The wind now makes for a vulnerable point, and gets his hat in chancery.  All ceremony is now thrown away; the luckless wretch seizes his hat with both hands, and charges madly at the front door.  Inch by inch, the wind contests the ground; another struggle, and he stands upon the veranda.  On such occasions I make it a point to open the door myself, with a calmness and serenity that shall offer a marked contrast to his feverish and excited air, and shall throw suspicion of inebriety upon him.  If he be inclined to timidity and bashfulness, during the best of the evening he is all too conscious of the disarrangement of his hair and cravat.  If he is less sensitive, the result is often more distressing.  A valued elderly friend once called upon me after undergoing a twofold struggle with the wind and a large Newfoundland dog (which I keep for reasons hereinafter stated), and not only his hat, but his wig, had suffered.  He spent the evening with me, totally unconscious of the fact that his hair presented the singular spectacle of having been parted diagonally from the right temple to the left ear.  When ladies called, my wife preferred to receive them.  They were generally hysterical, and often in tears.  I remember, one Sunday, to have been startled by what appeared to be the balloon from Hayes Valley drifting rapidly past my conservatory, closely followed by the Newfoundland dog.  I rushed to the front door, but was anticipated by my wife.  A strange lady appeared at lunch, but the phenomenon remained otherwise unaccounted for.  Egress from my residence is much more easy.  My guests seldom “stand upon the order of their going, but go at once”; the Newfoundland dog playfully harassing their rear.  I was standing one day, with my hand on the open hall door, in serious conversation with the minister of the parish, when the back door was cautiously opened.  The watchful breeze seized the opportunity, and charged through the defenceless passage.  The front door closed violently in the middle of a sentence, precipitating the reverend gentleman into the garden.  The Newfoundland dog, with that sagacity for which his race is so distinguished, at once concluded that a personal collision had taken place between myself and visitor, and flew to my defence.  The reverend gentleman never called again.
