I cannot tell how it may appear to others, but to me it seems 
that the inducement to record the thoughts and feelings of a mind 
and heart thus influenced, is so strong as to be almost irresistible, 
so that I think we do not err in concluding that where such a 
record is absent, the feeling that would prompt its production 
must have been absent too. 
The temptation to pursue this theme is great, but we must 
refrain. Dallying by the way in search of objects that we set not 
out to find, will perhaps only rob us in this case, as it often does 
in others, of time that might be more beneficially employed. Let 
us therefore keep to the path direct. 
Scenery may be viewed from two very different standpoints— 
the esthetic, and the scientific. From the former we see and are 
pleased, but know not why, and care not wherefore. From the 
latter we must know why, or we cannot be pleased at all. From 
the esthetic point of view we may experience the fullest enjoyment 
without knowing anything of the order of effects by which the 
scene resulted, for there is in it then something that— 
‘* Hath no need of a remoter charm by thought supplied, 
Nor any interest unborrowed from the eye.” 
From the scientific standpoint we can only be satisfied by a know- 
ledge of the cause, be it remote or mediate, which has led to such 
an elaborate effect. 
It is from the latter point of view that I invite you for a short 
time to look at scenery now. Premising that there are some 
among you who have not taken up that position before, it may be 
necessary, in order that you may fully appreciate the prospect, to 
make a few preliminary observations. This, with your permission, 
I will now proceed to do. 
The exterior portion of the earth’s crust, with which alone we 
are acquainted, is known by common observation to be composed 
of different kinds of rocks. These we find on examination may 
be separated into two classes—aqueous and igneous—the former 
having originated in water, the latter by fire. Among the water- 
formed rocks are our limestones, sandstones, and slates, which
