It went on all day, and continued far into the night, until it was too late to go to the theatre, too late to do anything but tumble into bed and simultaneously fall asleep. They groaned over their reiterated disappointments, but they could not deny that the interest was unfailing, and that they got a great deal of fun out of it all. Nothing could abate Mrs. March's faith in her advertisements. One of them sent her to a flat of ten rooms which promised to be the solution of all their difficulties; it proved to be over a livery-stable, a liquor store, and a milliner's shop, none of the first fashion. Another led them far into old Greenwich Village to an apartment-house, which she refused to enter behind a small girl with a loaf of bread under one arm and a quart can of milk under the other. In their search they were obliged, as March complained, to the acquisition of useless information in a degree unequalled in their experience. They came to excel in the sad knowledge of the line at which respectability distinguishes itself from shabbiness. Flattering advertisements took them to numbers of huge apartment-houses chiefly distinguishable from tenement-houses by the absence of fire-escapes on their facades, till Mrs. March refused to stop at any door where there were more than six bell-ratchets and speaking-tubes on either hand. Before the middle of the afternoon she decided against ratchets altogether, and confined herself to knobs, neatly set in the door-trim. Her husband was still sunk in the superstition that you can live anywhere you like in New York, and he would have paused at some places where her quicker eye caught the fatal sign of “Modes” in the ground-floor windows. She found that there was an east and west line beyond which they could not go if they wished to keep their self-respect, and that within the region to which they had restricted themselves there was a choice of streets. At first all the New York streets looked to them ill-paved, dirty, and repulsive; the general infamy imparted itself in their casual impression to streets in no wise guilty. But they began to notice that some streets were quiet and clean, and, though never so quiet and clean as Boston streets, that they wore an air of encouraging reform, and suggested a future of greater and greater domesticity. Whole blocks of these downtown cross-streets seemed to have been redeemed from decay, and even in the midst of squalor a dwelling here and there had been seized, painted a dull red as to its brick-work, and a glossy black as to its wood-work, and with a bright brass bell-pull and door-knob and a large brass plate for its key-hole escutcheon, had been endowed with an effect of purity and pride which removed its shabby neighborhood far from it. Some of these houses were quite small, and imaginably within their means; but, as March said, some body seemed always to be living there himself, and the fact that none of them was to rent kept Mrs.
