"Finally, every kind of vehicle having disappeared, the house-doors are left ajar; the inmates like to fraternise in the street. On fine evenings the footpath gets strewed with chairs and benches, occupied by men smoking--women chatting _al fresco_ unreservedly--laughing that loud laugh which says, "I don't care who hears me." Passers-by exchange a remark, children play at foot-ball, while the house-dog, exulting in the enjoyment of sweet liberty, gambols in the very midst of the happy crowd. These are good streets. One travels over them cheerfully and gaily. An atmosphere of rowdyism, theft, wantonness, hovers over some thoroughfares. Dread and disgust accompany him who saunters over them. Their gates and doorways seem dark--full of pit- falls. Iron shutters, thick doors with deep gashes, indicate the turbulent nature of their inhabitants. Rude men on the sidepaths stare you out of countenance, or make strange signs--a kind of occult telegraphy, which makes your flesh creep. To guard against an unseen foe, you take to the centre of the street--nasty and muddy though it should be,--for there you fancy yourself safe from the blow of a skull-cracker, hurled by an unseen hand on watch under a gateway. The police make themselves conspicuous here by their absence; 'tis a fit spot for midnight murder and robbery--unprovoked, unpunished. Honest tradesmen may reside here, but not from choice; they are bound to ignore street rows; lending a helping hand to a victim would cause them to receive, on the morrow, a notice to quit. "Be on your guard, if necessity brings you, after nightfall, to this unhallowed ground. Danger hovers over, under, round your footsteps. If an urchin plays a trick on you at a street corner, heed him not. Try and catch him, he will disappear to return with a reinforcement of roughs, prepared to avenge his pretended wrongs by violence to your person and injury to your purse. "Should a drunken man hustle you as he passes, do not mind him: it may end in a scuffle, out of which you will emerge bruised and with rifled pockets.
