244 A STROLL BY THE SEA-SIDE. 
In contemplating the many complete provisions made for 
these lower animals in procuring their food, one is ledt 
admire the adaptability of ciliary motion which appears to 
take so prominent a part in the functions of the lower aui- 
mals. Among the lowest forms of life, locomotion is effectel 
entirely by ciliary motion; among others, food is broug 
within the compass of their mouth, and the gills are contit- 
ually bathed with fresh water. Generative products ai — 
brought together for the impregnation of the eggs. Tt 
new-born animal is borne safely to some place of attachment, — 
or to a proper position for future growth. 
A large and ponderous mussel, called the Horse-mus 
may be torn out from the crevices of the rock just at 0 
water mark, and the roots of the large sea-weed, commonly 
called the “devils apron,” are often found entwined oF 
specimens of this species. While speaking of this gig% 
tic sea-weed, we may say that after storms, and in fact it 
nearly all times, this Laminaria, as it is technically termed, 
may be found on the shores, and the collector must nerit 
fail to examine carefully every portion of it for novelties 
On the broad crenulated brown frond he will find č 
species of snails browsing. On the stem, patches of ; 
rious growth, looking like the most delicate lace, may 
seen; strange as it may appear, each little cell, comp 
this lace-work, is occupied by a tiny animal, whose Wi 
lations are with the clams and oysters. In the tangled: 
the collector often reaps a rich harvest of marme 
brittle starfishes, minute crustaceans, and many othera 
The reason why this sea-plant affords such an M 
field for the collector is, that it comes from bey 
water mark. In the sea, as on the land, there are 
zones of animal and plant-life. Thus on the land we 
low places certain species of plants and trees ; a lit 
we have the hard-wood growths; on the mountain S" 
pines and spruces flourish, while near the tops pe 
mountains lichens only can exist, and at the highe 
tions the bare rocks alone meet the eye.
