The number of vocal performers are rising two hundred, male and female ; an adequate number of instrumental performers are engaged, and, on the whole, it is presumed that this will form one of the most interesting points in the day's festivity. The splendid banner, painted by Mr. Smith, and intended as a present to the Fire Department by the city authorities, will be presented by His Honor the Mayor to the Board of Trustees of the Fire Department Fund, who are delegated by the Department to receive it, at nine o'clock in the morning, in front of the City Hall.

General Gilbert Hopkins has been selected as the Grand Marshal of the day, who has selected twenty-six gentlemen as aids. The day will be ushered in by the firing of a national salute by the veteran corps, under the command of Capt. Chapman, who has kindly consented to perform that duty. The bells of the diiferent churches in the city are directed to be rung one hour at sun-rise, at noon, and at sun-down. The line will be formed under the direction of the Grand Marshal and aids, in Broadway the right on Battery Place at nine o'clock, and will move precisely at ten o'clock. The whole line will countermarch up Broadway to Union Place down the Bowery to Grand- street up Grand street to East Broadway down East Broadway to Chathamstreet down Chatham-street to the Park. The Committee are desirous that the Inspectors of the streets through which the procession will pass, should be particularly instructed to have the streets cleaned, and that no vehicles or fruit-carts be allowed in them.
