of these livid flames,
was not so utterly obscure as over the vault of the heavens.' Even in
our own seas very beautiful displays of phosphorescence may be
witnessed. On fine summer nights, a soft, tender light plays round the
boat as it moves onward, and the oars drop liquid fire. For how much
of beauty are we indebted to these living specks of jelly?

Of the extreme minuteness of some of the species, an idea may be
formed from the fact, that 110,000 might be contained in a cubic foot
of water. We can say nothing with certainty as to the cause of the
phosphorescence of the medusae, and shall not trouble our readers with
mere speculations.

The jelly-fishes furnish us with a striking illustration of the
profusion of life in the ocean. Provision has indeed been made for
securing in all the realms of our globe the largest possible amount of
sentient being, and consequently of happiness. And to each tribe a
definite part is assigned--a special mission is intrusted. None can be
spared from the economy of nature. The shoals of microscopic medusae
store up in their own tissues the minute portions of nutritious matter
diffused through the waters, and supply food for the support of higher
organisms. All the tribes of animated beings are dependent one upon
another. That the greatest may enjoy its existence and fulfil its
work, the least must hold its place and discharge its function. They
co-operate unconsciously to secure the unity and harmony of a system
which is designed to promote alike the interests of each and all of
them.

STEEPLE-JACK'S SECRET.

You want me to tell you how it comes to pass that I am able to glide
up a steeple like a spider, get astride upon the cross, and pull off
my cap to the crowd below, like a gentleman on horseback saluting his
acquaintances.[2] You want me to explain on what principle, as you
call it, I do this. Well: principle, I suppose, means the rule or law
by which a man does what he ought to do; and if so, it is a very good
word to use. I will oblige you by explaining my principle, for I am as
affable as any man that creeps to his dying day upon the surface of
the earth; and I will tell you how it chanced that I found it out: at
least I will try, for I am no scholar; and if you wish to understand
me, you must have your ears open, and catch a meaning when you can.
And this will do you good, whether you make anything out or not. I
know fellows that go to the lectures, and come back
