Rock carvings of a very different character were discovered by the author in the Touareg (Tawarek) country on the first slopes of the Hoggar (Ahaggar) massif, 200-300 kilometres south of In Salah. Some are scribblings in which animals and men are represented diagrammatically, and with these inscriptions are associated. M. Flamand some time ago described entirely similar graffiti in South Oranais which he identified as “Libyco-berbères." The greater part of the figures in this paper illus trate engravings of a very different character, and are far less ancient than those just referred to, for the animals represented are forms that still exist there. The presence of the camel is very significant, since it is generally admitted that it was only introduced, or re-introduced into north-west Africa in the first centuries of our era, and appears to have been abundant there about the period of Justinian.
