Departureof the comet

The comet will leave New York at 10 P.M. on the 20th inst., and therefore it will be desirable that the passengers be on board by eight at the latest, to avoid confusion in getting under way.  It is not known whether passports will be necessary or not, but it is deemed best that passengers provide them, and so guard against all contingencies.  No dogs will be allowed on board.  This rule has been made in deference to the existing state of feeling regarding these animals, and will be strictly adhered to.  The safety of the passengers will in all ways be jealously looked to.  A substantial iron railing will be put up all around the comet, and no one will be allowed to go to the edge and look over unless accompanied by either my partner or myself.

Thepostal service

will be of the completest character.  Of course the telegraph, and the telegraph only, will be employed; consequently friends occupying state-rooms 20,000,000 and even 30,000,000 miles apart will be able to send a message and receive a reply inside of eleven days.  Night messages will be half-rate.  The whole of this vast postal system will be under the personal superintendence of Mr. Hale of Maine.  Meals served at all hours.  Meals served in staterooms charged extra.

The inhabitants of stars

of the tenth or twentieth magnitude.  We shall in no case wantonly offend the people of any star, but shall treat all alike with urbanity and kindliness, never conducting ourselves toward an asteroid after a fashion which we could not venture to assume toward Jupiter or Saturn.  I repeat that we shall not wantonly offend any star; but at the same time we shall promptly resent any injury that may be done us, or any insolence offered us, by parties or governments residing in any star in the firmament.  Although averse to the shedding of blood, we shall still hold this course rigidly and fearlessly, not only toward single stars, but toward constellations.  We shall hope to leave a good impression of America behind us in every nation we visit, from Venus to Uranus.  And, at all events, if we cannot inspire love we shall at least compel respect for our country wherever we go.  We shall take with us, free of charge,

A great force of missionaries,

and shed the true light upon all the celestial orbs which, physically aglow, are yet morally in darkness.  Sunday-schools will be established wherever practicable.  Compulsory education will also be introduced.
