"To-morrow may be too late," interrupted a large and muscular man. "The post-office is more active than ever to-night. Every moment couriers are arriving and departing. That powerful instrument remains in the hands of the foes of our cause! Who may estimate the injury, the irreparable injury which they may this night accomplish by its means!"

This man was Étienne Arago, brother of the great astronomer, and, for sixteen years, celebrated as one of the boldest members of the Republican party, as well as one of the bravest men in Paris.

"And the préfecture of police," observed another—"the present utter derangement of all its functions may lead to most serious results. Already those foes of freedom, Guizot and his colleagues, have been suffered to secure their escape from the just indignation of an outraged people. Delessert, the Préfect, has also fled!"

The man who said this was Marc Caussidière, a well-known Republican.

"Citizens!" cried M. Gouache, "this state of things must continue no longer. In the name of the people, I demand that Étienne Arago immediately assume the charge of the post-office, as its director, and that Marc Caussidière fill the position of Préfect."

This demand was confirmed by acclamation, and committees for the installation of the nominees into office at once accompanied them to their respective departments.

The immense edifice of the post-office was surrounded by people, and its numerous windows were flashing with lights. Within the utmost activity seemed to prevail, and without couriers were leaving and arriving every moment, and mail coaches were dashing up to discharge their burdens, or, having received them, were dashing off.

"In the name of the people, entrance for Citizen Étienne Arago, Republican director of the post-office!" shouted one of the committee.

Instantly a passage through the immense crowd in the courtyard was cleared by the National Guard, and the director entered with his escort.
