But it should be remembered also in this connection that in the period just mentioned the mechanical industries of the South were carried on mostly by slaves, and that bits of history gathered here and there show that many of the simple mechanical contrivances of the day were devised by the Negro in his effort to minimize the exactions of his daily toil. None of these inventions were patented by the United States as being the inventions of slaves; and it is quite conceivable that some inventions of value perfected by this class will be forever lost sight of through the attitude at that time of the Federal Government on that subject. In 1858 Jeremiah S. Black, Attorney-General of the United States, confirmed a decision of the Secretary of the Interior, on appeal from the Commissioner of Patents, refusing to grant a patent on an invention by a slave, either to the slave as the inventor, or to the master of the latter, on the ground that, not being a citizen, the slave could neither contract with the government nor assign his invention to his master.
