W. S. Lindsay, History of merchant shipping and ancient commerce… (1876)
“ I use the word “vain” because it is clear, if the experience of other nations, or the experience of your own nation is of any value, that all the money paid to “encourage shipping” is actually lost, for French ships, with all this protection, do not increase at the same rate as other nations, or at the same rates in the branches of your own trade, where they are guarded with unusual care, as they do in those branches where they are thrown into competition with the shipping of other countries. ”
