The House-Tops! What a soberizing effect that prospect produces on the mind. But a great many requisites go towards the selection of the right point of survey. It is not enough to secure a lodging in the attic; you must not be fobbed off with a front attic that faces the street. First, your attic must be unequivocally a back attic; secondly, the house in which it is located must be slightly elevated above its neighbors; thirdly, the window must not lie slant on the roof, as is common with attics,--in which case you can only catch a peep of that leaden canopy which infatuated Londoners call the sky,--but must be a window perpendicular, and not half blocked up by the parapets of that fosse called the gutter; and, lastly, the sight must be so humored that you cannot catch a glimpse of the pavements: if you once see the world beneath, the whole charm of that world above is destroyed. Taking it for granted that you have secured these requisites, open your window, lean your chin on both hands, the elbows propped commodiously on the sill, and contemplate the extraordinary scene which spreads before you. You find it difficult to believe life can be so tranquil on high, while it is so noisy and turbulent below. What astonishing stillness! Eliot Warburton (seductive enchanter!) recommends you to sail down the Nile if you want to lull the vexed spirit. It is easier and cheaper to hire an attic in Holborn! You don't have the crocodiles, but you have animals no less hallowed in Egypt,--the cats! And how harmoniously the tranquil creatures blend with the prospect; how noiselessly they glide along at the distance, pause, peer about, and disappear! It is only from the attic that you can appreciate the picturesque which belongs to our domesticated tiger-kin! The goat should be seen on the Alps, and the cat on the house-top.
