He himself spoke French fluently, and to this may be ascribed the first change in his fortunes. Easy in his mind respecting Rachel, easy respecting money, he found himself at leisure to look about him and observe. He made friends, and among them a poor French engineer of great skill. In conversation one day this engineer mentioned that tenders were invited for the construction of a local bridge. It was not a very important matter; the lake it was to span was of no great dimensions, and the bridge required was by no means formidable. "There are only two contractors who will tender for it," said the engineer, "and they are in each other's confidence. They will settle privately the amount of their separate tenders, and the lowest will obtain the contract. They will divide the profits between them. If I had a little money to commence with I would tender for the work, and my tender would be at least ten thousand francs below theirs. Then it would be I who would construct the bridge, and public money would be saved." "What would be your profit?" asked Aaron. "Twenty thousand francs," was the reply, "perhaps more." "And the amount of your tender?" "Eighty thousand francs. I have the plans and specifications, and every detail of expense for material and labor, in my house. Will you come and look over them?" Aaron examined them, and submitting them to the test of inquiry as to the cost of labor and material, found them to be correct. A simple-minded man might have been taken in by a schemer who had prepared complicated figures for the purpose of trading with another person's money, and standing the chance of losing or winning; but Aaron was not simple-minded, the poor engineer was not a schemer, and the figures were honestly set down. "It would not need a great amount of money," said the engineer. "If a certain sum were deposited in the bank a further sum could be raised upon the signed contract being given as security, and moreover, as the work proceeds, specified payments will be made by the local authorities." "How much would be required to commence operations, and to make everything safe?" "Ten thousand francs." Roughly, that was four hundred pounds. The five hundred pounds he had received from the lawyers were as yet untouched, for they lived very economically, and they were in a part of the world where thrift was part of the people's education. Aaron believed the project to be safe. "If I advance it?" he asked. "We would make it a partnership affair," replied the poor engineer eagerly.
