PLATE V. 



Fig. 1. Aerolite, Long Island, Phillips Co., Kansas. This was probably a single 

 mass, broken in pieces by striking on a ledge as it fell. Four of the largest 

 of the fragments have been joined together along the planes of original 

 fracture, giving the mass shown in the -figure. The other fragments occu- 

 pied the place of the pedestal. The white coating shown over a portion 

 of the surface was undoubtedly formed subsequent to the fall of the stone. 

 The true crust has the appearance of an earthenware glaze. 



Fig. 2. Seven individual aerolites, Leland, Winnebago Co., Iowa, showing crust, 

 pitted surface and interior.
