battery which shall speak instantly and distinctly to the ends of
the earth. The mind of that astronomer is a telescope, through whose
increasing field new worlds float daily by; the mind of that geologist
is a divining-rod, forever bending toward the waters of chaos, and
pointing out new places where a shaft can be sunk into periods of almost
infinite antiquity; the mind of that chemist is a subtile crucible, in

The ambition is everywhere,--in every breast; the power is
everywhere,--in every brain. The giant and the pigmy are alike active
in seeking out and finding out many inventions. And in this very

see that magnificent widening of its channel, in which, like the Amazon,
it long anticipates the sea.

Man, the great achiever! the marvellous magician! Look at him! A head
hardly six feet above the ground out of which he was taken. His "dome
of thought and palace of the soul" scarce twenty-two inches in

universe at home? How long will it be before this inherent power, laid
