Henson and Sir George
Cayley--had much weakened the public interest in the subject of aerial
navigation. Mr. Henson's scheme (which at first was considered very
feasible even by men of science,) was founded upon the principle of an
inclined plane, started from an eminence by an extrinsic force, applied
and continued by the revolution of impinging vanes, in form and number
resembling the vanes of a windmill. But, in all the experiments made
with models at the Adelaide Gallery, it was found that the operation of
these fans not only did not propel the machine, but actually impeded
its flight. The only propelling force it ever exhibited, was the mere
_impetus_ acquired from the descent of the inclined plane; and this
_impetus_ carried the machine farther when the vanes were at rest, than
when they were in motion--a fact which sufficiently demonstrates their
inutility; and in the absence of the propelling, which was also the
_sustaining_ power, the whole fabric would necessarily descend.
This consideration led Sir George Cayley to think only of adapting
a propeller to some machine having of itself an independent power of
support--in a word, to a balloon; the idea, however, being novel,
or original, with Sir George, only so far as regards the mode of its
application to practice. He exhibited a model of his invention at the
Polytechnic Institution. The propelling principle, or power, was here,
also, applied to interrupted surfaces, or vanes, put in revolution.
These vanes were four in number, but were found entirely ineffectual in
moving the balloon, or in aiding its ascending power. The whole project
was thus a complete failure.

"It was at this juncture that Mr. Monck Mason (whose voyage from Dover
to Weilburg in the balloon, "Nassau," occasioned so much excitement in
1837,) conceived the idea of employing the principle of the Archimedean
screw for the purpose of propulsion through the air--rightly
attributing the failure of Mr. Henson's scheme, and of Sir George
Cayley's, to the interruption of surface in the independent vanes.
He made the first public experiment at Willis's Rooms, but afterward
removed his model to the Adelaide Gallery.

"Like Sir George Cayley's balloon, his own was an ellipsoid. Its
length was thirteen feet six inches--height, six feet eight inches. It
contained about three hundred and twenty cubic feet of gas, which, if
pure hydrogen, would support twenty-one pounds upon its first inflation,
before the gas has time to deteriorate or escape. The weight of the
whole machine and apparatus was seventeen pounds--leaving about four
pounds to spare. Beneath the centre of the balloon, was a frame of light
wood, about nine feet long, and

Probably there is the usual amount of poetic exaggeration in these reminiscences, but they are almost the only record we have of that portion of his career and, therefore, apart from their literary merits, are on that account deeply interesting.

So many fables have been published about Poe, and even many fictitious documents quoted, that it behoves the unprejudiced to be wary in accepting any new statements concerning him that are not thoroughly authenticated.

I was ambitious--have you known The passion, father? You have not: A cottager, I marked a throne Of half the world as all my own, And murmured at such lowly lot-- But, just like any other dream, Upon the vapor of the dew My own had past, did not the beam Of beauty which did while it thro' The minute--the hour--the day--oppress My mind with double loveliness.

That the final destruction of the earth must be brought about by the agency of fire, was urged with a spirit that enforced everywhere conviction; and that the comets were of no fiery nature (as all men now knew) was a truth which relieved all, in a great measure, from the apprehension of the great calamity foretold.

That the extent of a poetical work is _ceteris paribus_, the measure of its merit, seems undoubtedly, when we thus state it, a proposition sufficiently absurd--yet we are indebted for it to the Quarterly Reviews.

My cheek is cold and white, alas! My heart beats loud and fast: O, press it close to thine again, Where it will break at last! Very few perhaps are familiar with these lines, yet no less a poet than Shelley is their author.

Ah, sad and strange as in dark summer dawns The earliest pipe of half-awaken'd birds To dying ears, when unto dying eyes The casement slowly grows a glimmering square; So sad, so strange, the days that are no more.

I determined, then, to place the lover in his chamber--in a chamber rendered sacred to him by memories of her who had frequented it.
