The Cairo Atheneum.

The benefit at the Atheneum, last evening, for the poor of Cairo, to the honor of our citizens be it said, was a substantial one, and well attended by the elite of the city. Too much credit could not be awarded the ladies for their energy and perseverance in raising funds for so noble a charity. Especial praise is due those estimable ladies, Miss Jennie Sloo, and Mrs. C. C. Davidson, for the leading part taken by them on the occasion. They will be remembered in the prayers of the poor, who, by their kind hands, have had their chilled hearts made glad. The performance went off very successfully. Mr. Crump, the lessee, is to be commended for the prompt manner in which he responded to the call of charity, and he has performed one more act showing that he is in more ways than one worthy of the support of our citizens. Nor should the employees of the Atheneum pass without their measure of praise. They all did nobly. We have not heard the sum realized for the poor, but it must have reached a goodly size.

We will give further notice of the benefit to the poor as soon as particulars can be procured.

To-night we are to have the long-talked-of, long-expected benefit of Mrs. Frank Graham. The bill is an excellent one, commencing with that old, but never stale or worm out comedy, in five acts, of Tobin, "The Honeymoon." The cast includes the names of several well-known citizens, who have kindly volunteered their services. "Juliana" is cast to Mrs. Graham, who will do ample justice to the part. "Duke Aranza," J. R. Vernon, a gentleman and an actor of merit. "Lampedo," Birney Marshall, late the leading editor of the Cairo Democrat. "Jaques," J. A. Signaigo, late the local editor of the same sheet. "Lopez," Ed. S. Trover, the present city editor of the daily News, and late the manager of the celebrated Edwards & Trover Dramatic-Troupe. Of Mr. Vernon we have no doubt. He is old to the boards, and can do the part well. Signaigo has worn the buskin, we believe. So has Edward, but we have never heard that Marshall professed to be an actor. Yet he has talent, enough for anything, and will undoubtedly do credit to himself and the author. There will be great curiosity to see the amateur, performers, and the [unknown] a full house.

The first place will be followed by a fancy dance by Mademoiselle Victoria, who danced last night with such splendid effect — and the evenings entertainment will close with the farce of "Chameleon," in which Mrs. Graham will play four different parts. The bill should call out a rousing house.
