386. C. Chamberlin—Hillocks of angular Gravel 
to moderately worn sand and gravel, and (8) of stratification, 
from contorted and disturbed beds to almost complete horizon 
tality. The interesting fact is that this occurs within the lim- 
ited compass of a single hill, it may be a mere hillock, scarcely 
exceeding in size an artificial tumulus. 
~ Inferences.—The following ‘inferences are drawn, if not alto-

The angular gravel is an immediate derivative from the ad-

complete series of gradations, and from the identity of its stony 
constituents with those of the till.
