If the new town of Algiers is interesting, however, the old town is unique, indescribable, incomprehensible. No map could reproduce it; no clue could unravel it. It climbs and clambers by tortuous lanes and steep staircases up the sheer side of a high hill to the old fortress of the Deys that crowns the summit. Not one gleam of sunshine ever penetrates down those narrow slits between the houses, where two people can just pass abreast, brushing their elbows against the walls, and treading with their feet in the poached filth of the gutter. The dirt that chokes the sides is to the dirt of Italy as the dirt of Italy is to the dirt of Whitechapel. And yet so quaint, so picturesque, so interesting is it all, that even delicate ladies, with the fear of typhoid fever for ever before their eyes, cannot refuse themselves the tremulous joy of visiting it and exploring it over and over again; nay, more, of standing to bargain for old brass-work or Algerian embroidery with keen Arab shopkeepers in its sunless labyrinths. Except the Mooskee at Cairo, indeed, I know no place yet left where you can see Oriental life in perfection as well as the old town of Algiers. For are there not tramways nowadays even in the streets of Damascus? Has not a railway station penetrated the charmed heart of Stamboul? The Frank has done his worst for the lower town of his own building, but the upper town still remains as picturesque, as mysterious, and as insanitary as ever. No Pasteur could clean out those Augean stables. In those malodorous little alleys, where every prospect pleases and every scent is vile, nobody really walks; veiled figures glide softly as if to inaudible music; ladies, muffled up to their eyes, use those solitary features with great effect upon the casual passer-by; old Moors, in stately robes, emerge with stealthy tread from half-unseen doorways; boys clad in a single shirt sit and play pitch-and-toss for pence on dark steps. Everything reeks impartially of dirt and of mystery. All is gloom and shade. You could believe anything on earth of that darkling old town. There all Oriental fancies might easily come true, all fables might revive, all dead history might repeat itself. These two incongruous worlds, the ancient and the modern town, form the two great divisions of Algiers as the latter-day tourist from our cold North knows it. The one is antique, lazy, sleepy, unprogressive; the other is bustling, new-world, busy, noisy, commercial. But there is yet a third Algiers that lies well without the wall, the Algiers of the stranger and of the winter resident. Hither Mr. Cook conducts his eager neophytes; hither the Swiss innkeeper summons his cosmopolitan guests. It reaches its culminating point about three miles from the town, on the heights of Mustapha Supérieur, where charming villas spread thick over the sunlit hills, and where the Western visitor can enjoy the North African air without any unpleasant addition of fine old crusted Moorish perfumes.
