haps a Spanish bayonet-plant, a stream of water with a 

 spring near the bank, a steel trap, a rude representation of 

 a canon blocked up by a snow-drift, and a snake at a nest of 

 eggs. 



Of the six remaining etchings Mr. Rock withheld his opin- 

 ion. As these remains are in the territory of the Apache 

 Indians, he attributed the work to them, and also suggested 

 that the early Spanish missionaries may have made the 

 crosses, as they .were more sharply cut and exact than the 

 others. 



The slope below these remains was littered over with flakes 

 of agate and chalcedony and a profusion of pot-sherds — both 

 plain and colored. There were, also, several mortars exca- 

 vated in the rocks of the cliff. 



Aboriginal Paint Quarry. 

 By ELMER R. REYNOLDS. 



Mr. Reynolds spoke of the discovery of an aboriginal paint 

 quarry near Bladensburg, Maryland, made in February last 

 while searching for the site of an old encampment among 

 the hills southeast of Benning's Bridge. The abandoned 

 quarry is situated near Indian Springs on the estate of Rev. 

 R. W. Lowrie. 



The stone was found in piles on the summit of the hill 

 above the spring. The mineral seemed richly impregnated 

 with iron. Some of the masses presented every appearance 

 of having been subjected to some great test of heat, as they 

 were twisted and honey-combed into a variety of fantastic 

 shapes. The speaker did no ascribe their igneous feature to 

 the Indians, but to some geological agency. 



The pigments are found in the cavities of the rock when 

 broken up. They are crimson and orange, and are bright 

 and vivid. Other shades were also observed, ranging from 

 carmine to a delicate purple.
