Under my window, in the street called Cossitollah, flows all the motliness of a Calcutta thoroughfare in two counter-setting currents;-- one Chowriagee-ward, in the direction of Nabob magnificence and grace; the other toward the Cooly squalor and deformity of the Radda Bazaar;-- and as, in the glare of the early forenoon sun, the shadows of the hither or thither passing throngs fall straight across the way, from the Parsee's _godown_, over against me, to the gate of the _pucca_ house wherein my look-out is, I watch with interest the frequent eddies occasioned by the clear-steerings of caste,--Brahmin, Warrior, and Merchant keeping severely to the Parsee side, so that the foul shadow of Soodra or Pariah may not pollute their sacred persons. It is as though my window were a tower of Allahabad, and below me, in Cossitollah, were the shy meeting of the waters. Thus, looking up or down, I mark how the limpid Jumna of high caste holds its way in a common bed, but never mingling with the turbid Ganges of an unclean rabble. Reader, should you ever "do" the City of Palaces, permit me to commend with especial emphasis to your consideration this same Cossitollah, as a representative street, wherein the European and Asiatic elements of the Calcutta panorama are mingled in the most picturesque proportions; for Cossitollah is the link that most directly joins the pitiful benightedness of the Black Town to the imposing splendors of Kumpnee Bahadoor,--the short, but stubborn chain of responsibility, as it were, whereby the ball of helpless and infatuated stock-and-stone-worship is fastened to the leg of British enlightenment and accountability. From the Midaun, or Parade Ground, with its long-drawn arrays of Sepoy chivalry, its grand reviews before the _Burra Lard Sahib_, (as in domestic Bengalee we designate the Governor-General,) its solemn sham battles, and its welkin-rending regimental bands, by whose brass and sheepskin God saves the Queen twice a day; from Government House, with its historic pride, pomp, and circumstance, and its red tape, its aides-de-camp, and its adjutant-birds, its stirring associations, and its stupid architecture; from the pensioned aristocracy of Chowringhee the Magnificent; from the carnival concourse of the Esplanade, with its kaleidoscopic surprises; from the grim patronage of Fort William, with its in-every-department well-regulated fee-faw-fum; in fine, from Clive, and Hastings, and Wellington, and Gough, and Hardinge, and Napier, and Bentinck, and Ellenborough, and Dalhousie, and all the John Company that has come of them; from the tremendous and overwhelming SAHIB, to that most profoundly abject of human objects, the Hindoo PARIAH, (who approaches thee, O Awful Being! O Benign Protector of the Poor! O Writer in the Salt-and-Opium Office! on his hands and knees, and with a wisp of grass in his mouth, to denote that he is thy beast,)-- from all those to this, the shortest cut is through Cossitollah.
