Water bottle used by explorer Robert O'Hara Burke on his 1860–61 expedition to the Gulf of Carpentaria.
Bulbous bladder-style dark leather water bottle that tapers from its reservoir to its neck. It has a seam around the edge, and a small leather loop is sewn into the seam on opposite sides. The bladder is sealed by a waxy band to a very dark brown turned animal horn spout, which has a white patch on one side. The horn cap is secured to the spout with coiled string. One face of the bladder has fine white crystalline deposits in the creases in the leather.
