INTERNAL STRUCTURE AND 
tion of water, frost, will combine to propel the 
mass at a greater rate along its axis than near 
its margins. For details concerning the facts of 
the case, I would refer to my work entitled “ Sys- 
teme Glaciaire.” 
We will next consider the stratification of the 
glacier. I have stated, in my introductory re- 
marks, that I consider this to be one of its pri- 
mary and fundamental features, and I confess, 
that, after a careful examination of the results 
obtained by my successors in the field of glacial 
phenomena, I still believe that the original strat- 
ification of the mass of snow from which the gla- 
cier arises gives us the key to many facts of its 
internal structure. The ultimate features result- 
ing from this connection are so exceedingly in- 
tricate and entangled that their relation is not 
easily explained. Nevertheless, I trust my read- 
ers will follow me in this Alpine excursion, where 
I shall try to smooth the asperities of the road for 
them as much as possible. 
Imparted to it, at the very beginning of its 
formation, by the manner in which snow accu- 
mulates, and retained through all its transfor- 
mations, the stratification of a glacier, however 
distorted, and at times almost obliterated, re- 
mains, notwithstanding, as distinct to one who 
is acquainted with all its phases, as is the strat
