“ Undoubtedly, since the fifties, manual labor, the old standby in preparing teas for foreign consumption, has been much improved with a view of retaining a large percentage of the tea trade in China. The reason why a large percentage of the tea business has passed away from China to India is not because machinery is used in the one case and manual labor is retained in the other, but chiefly on account of the quality of the tea that is raised in the different soil of the two countries. The Indian or Assam tea is much stronger (in proportion to the same quantity) than the Chinese tea. ”
