Explanation of Plate II. 
Above 
The home of the Worker in Stone. This is a view from an aeroplane 
looking north-east. It shows the complete isolation of White Rocks. In the 
right corner runs the stream in double “S” formation. The white streak at 
the extreme right is the tail of the aeroplane. 
Middle 
The entrances to the nests are generally found on the upper surfaces of 
certain dome-shaped sandstone formations. In the background runs the 
stream which has carved the cliffs of Wliite Rocks. Ten or twelve nests are 
present in this picture. 
Below 
A peculiar nest that was over-tunneled by the bees. This photograph 
was taken, after the sand containing the cells had been scraped away, in order 
to give depth to the drawing in Fig. 4. (Approximately one-fourth natural 
size.)
