Coming to statutes which merely facilitate business as it now exists, by far the most important movement has been the successful work of the State Commissioners on Uniformity of Law in getting their negotiable instrument act passed in nearly all the States, and in several already their uniform law statute on sales, only recommended in 1907. Some progress has been made in getting a uniform standard of weights and measures, and there is an increasing tendency to prescribe specific weights and markings for packages--possibly unconstitutional legislation. Still more important as a change in previously existing law has been the increasing tendency to make documents other than bills and notes negotiable. Perhaps this is a matter which requires explanation to the lay reader. The early Anglo-Saxon law could not conceive of ownership of property as distinct from possession, and to their simple minds, when ownership was once acquired it was impossible to divest the owner of his property by any symbolical delivery. Hence the very early statutes making fraudulent sales or conveyances of property without actual and visible change of possession. The notion of a symbol, a paper or writing, which should represent that property would probably have impressed them like a spell or charm in a child's fairy tale. Even theft with asportation could not alter property rights, even in favor of innocent purchasers, when the owner did not intend to part therewith. A moment's recollection of what is now perhaps the most familiar of Teutonic saga to the ordinary reader, the text of Wagner's "Ring of the Nibelung," will give ample evidence of that mental attitude. But the Oriental mind was far more subtile. To the Jews or Lombards we owe the discovery of that _bill of exchange_--the first of negotiable instruments, and the first historically to bring into our law the legal concept of a symbol of ownership which might be instantly transferred with an absolute change of title in the property thereby represented, and this either to a present transferee or to one far away. Thus, a simple bill of exchange might transfer the ownership in a pile of gold in a moment from a man in Venice to a man in London, thereby (if the law-merchant was respected) freeing the treasure itself from attack at the hands of the Venetian authorities. And not only was this change of ownership instantaneously effected by the transfer of some symbol or document representing it, but there also, and as a necessary part of the invention, grew up the doctrine that the transferee was relieved of any claims against the property at the hands of the previous owner. This is what we mean by negotiable; and it is essential that the precise meaning of the word should be understood if we are to understand the importance of this legislation. Even most business men have a very vague understanding of the difference between _negotiable_ and _assignable_. Substantially
