Such is a brief recapitulation of some of the leading features of the world of waters. Well may we say with the Psalmist : They that go down to the sea in ships, and occupy their business in great waters; these men see the works of the Lord, and His wonders in the deep.” Not that it is requisite for us to “occupy our business in great waters” in order to become acquainted with the wonders of creation as displayed in this department of the natural world: a simple drop of dew on a blade of grass, a flake of snow, a shower of rain falling to the earth, a small portion of water poured from one vessel to another, the process of evaporation perpetually carried on about and around us, each and all of these, though less striking on account of their fami. liarity, equally bear the impress of Divine wisdom, power, and goodness.

acknowledge this, but let us also feel it; and
then shall we reverentially exclaim with Bishop
Hall, "O God, the heart of man is too strait
to admire enough, even that which he treads
upon: what shall we say to Thee, the Maker of
all these?” Or, in the words of the Russian
poet, Derzhavin :-
« In its sublime research, philosophy

May measure out the ocean deep-may count
The sands, or the sun's rays—but, God! for Thee
There is no weight nor measure-none can mount
Up to Thy mysteries.
Thou art, and wert, and shalt be! glorious! great!
Life-giving, life-sustaining Potentate!
Thy chains the unmeasured universe surround;
Upheld by Thee! by Thee inspired with breath!
Thou the beginning with the end hast bound,
And beautifully mingled life with death.
