THE STEAM BOAT ILLUSTRATED.

_By one of "the Islington, Gray's Inn Lane, and New Road Grand
Literary, Scientific, and Philosophical Institution._


How wondrous is the science of mechanism! how variegated its progeny,
how simple, yet how compound! I am propelled to the consideration of
this subject by having optically perceived that ingenious nautical
instrument, which has just now flown along like a mammoth, that monster
of the deep! You ask me how are steam-boats propagated? in other words,
