Rensselaer Republican, Volume 22, Number 38, Rensselaer, Jasper County, 22 May 1890 — Natural Ink. [ARTICLE]

Natural Ink.

There is a plant in New Granada known as the “ink plant,” the juice of which serves, without any preparation, as ink. The writing at first appears red, but in a few hours assumes a deep black hue. Several sheets of manuscript, written with this natural ink, became soaked with sea water on their journey to Europe, but when dried the writing was found to be still perfectly dear. A guide much patronized by American tourists in Amsterdam, Holland, bears the name of Vanderbilt.
