IN sending out this little volume to the Ameri can public, I do so with the earnest hope of call ing attention to this very important branch of industry. Close study and observation on practical lines for more than ten years gives me confidence to assert that no one factor in the industrial inter ests of our nation is of greater importance than is the production of silk, and yet there is none so little understood, and hence so lightly valued. The wealth of every nation lies in its developed resources. We might build castles of stone upon mountains of gold, but the gold, though of greater intrinsic value, would be no better than (if as good) the stone employed in the super structure of the building. Wealth, in order to be helpful, either to the individual or the nation, must be developed; otherwise it will forever remain like the talent folded away in the napkin.
