The salary of the chief was not merely derived from his own demands upon the goods stolen, or from any voluntary contribution of the robbers themselves, but was probably a fixed remuneration granted by the government, as one of the chiefs of the police; nor is it to be supposed that he was any other than a respectable citizen, and a man of integrity and honor. The same may be said of the modern "_shekh_ of the thieves," at Cairo, where this very ancient office is still retained. The great confidence reposed in the public weighers rendered it necessary to enact suitable laws in order to bind them to their duty; and considering how much public property was at their mercy, and how easily bribes might be taken from a dishonest tradesman, the Egyptians inflicted a severe punishment as well on the weighers as on the shopkeepers, who were found to have false weights and measures, or to have defrauded the customer in any other way; and these, as well as the scribes who kept false accounts, were punished (as before stated) with the loss of both their hands; on the principle, says Diodorus, that the offending member should suffer; while the culprit was severely punished, that others might be deterred from the commission of a similar offence. As in other countries, their laws respecting debt and usury underwent some changes, according as society advanced, and as pecuniary transactions became more complicated. Bocchoris (who reigned in Egypt about the year 800 B.C., and who, from his learning, obtained the surname of Wise), finding that in cases of debt many causes of dispute had arisen, and instances of great oppression were of frequent occurrence, enacted, that no agreement should be binding unless it were acknowledged by a written contract; and if any one took oath that the money had not been lent him, that no debt should be recognized, and the claims of the suing party should immediately cease. This was done, that great regard might always be had for the name and nature of an oath, at the same time that, by substituting the unquestionable proof of a written document, the necessity of having frequent recourse to an oath was avoided, and its sanctity was not diminished by constant repetition.
