Green, near Tunbridge Wells. On examining the lower part of the 

 trunk close to the root, a large excavation was discovered, rendering 

 the base of the tree quite hollow : this cavity was filled with a large 

 nest somewhat resembling a wasp's nest, but of looser materials, 

 being composed of cells or separate excavations, the sides of which 

 were tough and pliable, and of a brownish colour, smelling strongly 

 of the sap of the tree, and filled with innumerable large black ants 

 and their eggs, quite alive; that is, not torpid. The tree had evi- 

 dently been excavated by them, and would in all probability have, ere 

 long, failed in its accustomed foliage, the cavit)' being very large ; it 

 appeared indeed to measure above a font in height, and the same in 

 diameter, tapering towards the upper part. I am not aware that 

 the nidus of this species of ant has ever been described ; and should 

 any of your correspondents wish it, I have not any doubt but a 

 drawing might be obtained, as the nest is preserved. — T. Forster.
