the very existence of the glacial formation, wherever it has remained 
undisturbed. While it is never stratified it is almost universally in 
a confused jumble. In looking at it in its typical state one might 
readily imagine that a world of diverse elements had come into con- 
tact helter-skelter. Fragments of rock of various sizes lie indiscrim- 
inately blended in the pasty matrix of finely comminuted stone. 
There is no order discernible in this mixture of heterogeneous ma- 
terials. In a word, its appearance is that-of a mass of matter, not 
assorted by water, or laid down in successive sheets, but thrown 
together pell-mell, and allowed to remain in that seemingly anoma- 
lous condition. Such being the case, it constitutes a peculiar kind 
of formation, if this term can be applied to that which has no regu- 
larity of form, and it is never likely to be confounded with other 
deposits. That its shape is not due to any ordinary form of atmos- 
pheric agency, or to aqueous deposition, should accordingly be evi- 
dent beyond a question. It may be added that it is usually im a 
comparatively loose state; in some places, however, it is found very 
compact; indeed, in rare instances, it is consolidated into firm rock. 
C. Indications from Incidental Phenomena. 
(1.) The accumulation of travelled matter. In some instances 
drift is met with in huge piles. Reference is made to the masses of 
jumbled heterogeneous material, ordinarily known as moraines. 
These are composed of rough, angular pieces of rock, varying in 
size from minute fragments to huge boulders weighing many tons. 
Moraines, as made up of such ungainly blocks and unpolished frag- 
ments, are very characteristic. Those described as terminal are, in 
given localities, of frequent occurrence. With them are usually 
associated other masses of unstratified matter, which seem to answer 
to lateral moraines. In places they are found in a good state of 
preservation. These terms are used, not as prejudging their mode 
of origin, but because they are perhaps more generally applied than 
any others to the masses of matter now in question. Closely related 
to these morainic heaps of earth, indeed appearing to owe their 
origin to substantially the same cause, are trains of boulders which 
have been variously named. They consist of long lines of travelled 
rocks, which are, to a great extent, parallel with each other. Of 
such boulder trains, perhaps among the most remarkable are those 
which occur in Huntington, Vermont, and in Richmond, Mass. 
How they could have assumed their existing attitude, unless in con-
