same is the case in another cave, the Trou du Ch6ne, where a 

 mass of yellow clay with stones separates the deposits of Palaeo- 

 lithic age from those that contain the relics of Neolithic and 

 more modern times. In the Tron de Pont-a-Lesse (which is a 

 mere shallow rock-shelter, situated some little distance from the 

 Trou Magrite, to be described in the following chapter) the 

 same yellow clay with stones is found. It is overlaid with a 

 loose superficial debris of fallen stones, amongst which occur two 

 bone-beds containing human bones and relics, which are referred 

 by M. Dupont to the Neolithic Age.
