In 1823 there were at Montfermeil neither so many white houses nor so many wellsatisfied citizens: it was only a village in the forest. Some pleasurehouses of the last century were to be met with there, to be sure, which were recognizable by their grand air, their balconies in twisted iron, and their long windows, whose tiny panes cast all sorts of varying shades of green on the white of the closed shutters。 but Montfermeil was none the less a village. Retired clothmerchants and rusticating attorneys had not discovered it as yet。 it was a peaceful and charming place, which was not on the road to anywhere: there people lived, and cheaply, that peasant rustic life which is so bounteous and so easy。 only, water was rare there, on account of the elevation of the plateau. It was necessary to fetch it from a considerable distance。 the end of the village towards Gagny drew its water from the magnificent ponds which exist in the woods there. The other end, which surrounds the church and which lies in the direction of Chelles, found drinkingwater only at a little spring halfway down the slope, near the road to Chelles, about a quarter of an hour from Montfermeil. Thus each household found it hard wor k to keep supplied with water. The large houses, the aristocracy, of which the Thenardier tavern formed a part, paid half a farthing a buc ketful to a man who made a business of it, and who earned about eight sous a day in his enterprise of supplying Montfermeil with water。 but this good man only wor ked until seven o39。clock in the evening in summer, and five in winter。 and night once e and the shutters on the ground floor once closed, he who had no water to drink went to fetch it for himse lf or did without it. This constituted the terror of the poor creature whom the reader has probably not fotten,little Cosette. It will be remembered that Cosette was useful to the Thenardiers in two ways: they made the mother pay them, and they made the child serve them. So when the mother ceased to pay altogether, the reason for which we have read in preceding chapters, the Thenardiers kept Cosette. She took the place of a servant in their house. In this capacity she it was BOOK CHAMPMATHIEU AFFAIR CHAPTER II THE PERSPICACITY OF MASTER SCAUFFLAIRE From the townhall he betook himself to the extremity of the town, to a Fleming named Master Scaufflaer, French Scaufflaire, who let out horses and cabriolets as desired. In order to reach this Scaufflaire, the shortest way was to take the littlefrequented street in which was situated the parsonage of the parish in which M. Madeleine resided. The cure was, it was said, a worthy, respectable, and sensible man. At the moment when M. Madeleine arrived in front of the parsonage there was but one passerby in the street, and this person noticed this: After the mayor had passed the priest39。s house he halted, stood motionless, then turned about, and retraced his steps to the door of the parsonage, which had an iron knocker. He laid his hand quic kly on the knoc ker and lifted it。 then he paused again and stopped short, as though in thought, and afte r the lapse of a few seconds, instead of allowing the knoc ker to fall abruptly, he placed it gently, and resumed his way with a sort of haste which had not been apparent previously. M. Madeleine found Master Scaufflaire at home, engaged in stitching a harness over. Master Scaufflaire, he inquired, have you a good horse? Mr. Mayor, said the Fleming, all my horses are good. What do you mean by a good horse? I mean a horse which can travel twenty leagues in a day. The deuce! said the Fleming. Twenty leagues! Yes. Hitched to a cabriolet? Yes. And how long can he rest at the end of his journey? He must be able to set out again on the next day if necessary. To traverse the same road? Yes. The deuce! the deuce! And it is twenty leagues? M. Madeleine drew from his pocket the paper on which he had pencilled some figures. He showed it to the Fleming. The figures were 5, 6, 8 1/2. You see, he said, total, nieen and a half。 as well say twenty leagues. Mr. Mayor, returned the Fleming, I have just what you want. My little white horseyou may have seen him pass occasionally。 he is a small beast from Lower Boulonnais. He is full of fire. They wanted to make a saddlehorse of him at first. Bah! He reared, he kicked, he laid everybody flat on the ground. He was thought to be vicious, and no one knew what to do with him. I bought him. I harnessed him to a carriage. That is what he wanted, sir。 he is as gentle as a girl。 he goes like the wind. Ah! indeed he must not be mounted. It does not suit his ideas to be a saddlehorse. Every one has his ambition. `Draw? Yes. Carry? No.39。 We must suppose that is what he said to himself. And he will acplish the trip? Your twenty leagues all at a full trot, and in less than eight hours. But here are the conditions. State them. In the first place. you will give him half an hour39。s breathing spell midway of the road。 he will eat。 and some one must be by while he is eating to prevent the stable boy of the inn from stealing his oats。 for I have noticed that in inns the oats are more often drunk by the stable men than eaten by the horses. Some one will be by. In the second placeis the cabriolet for Monsieur le Maire? Yes. Does Monsieur le Maire know how to drive? Yes. Well, Monsieur le Maire will travel alone and without baggage, in order not to overload the horse? Agreed. But as Monsieur le Maire will have no one with him, he will be obliged to take the trouble himself of seeing that the oats a re not stolen. Th
