On the 3d of August, 1857, the Marshes played _Black-eyed Susan_ at Laura Keene's Theatre here, followed by _The Toodles_. From the bill of this, their opening night, the following casts are copied: BLACK-EYED SUSAN. William Miss Louisa Marsh. Gnatbrain Master George H. Marsh. Tom Bowling Master Alfred (Stewart). Admiral Master Waldo (Todd). Dolly Mayflower Miss Carrie (Todd). Black-eyed Susan Miss Mary Marsh. TOODLES. Timothy Toodles Master George H. Marsh. George Acorn Miss Louisa Marsh. Tabitha Toodles Miss Mary Marsh. This was probably the last season of the Marsh Juveniles in New York, and since their exit no startling troupe of Phenomena have appeared here. The Boone and the Holman Children were clever, but not so successful as the Marshes. The Worrell Sisters were popular, but, although young girls, they were in their teens, and scarcely came under the head of infant players. They made their New York _debut_ at Wood's Theatre, 514 Broadway, afterwards the Theatre Comique, under the management of George Wood, in a burletta called _The Elves_, April 30, 1866, Miss Sophie Worrell, the eldest of the three sisters, being at that time fully eighteen years of age. Among the occasional companies of children who have appeared in New York were "The Mexican Juvenile Troupe." They occupied Mr. Daly's Fifth Avenue Theatre during the summer season of 1875, remaining two weeks, and appearing at the Lyceum Theatre, on Fourteenth Street, from the 1st to the 13th of November in the same year. Their performances were conducted in the Spanish language, and their specialty was opera-bouffe. They were well trained in voice and action, but the music in their childish treble was weak; and, personally, the troupe ran to legs and arms and hands and feet, and the general angular and awkward undevelopment characteristic of their age and size. The bit of a _prima donna_ who sang La Grand Duchesse and La Belle Helene in the titular parts, and who was known to fame as Signorina Carmen Unda y Moron, was made up carefully after Tostee, whom, in certain actions and gestures and expression of face, she much resembled. She displayed all of the vim and _abandon_ and _chic_ of the veteran actress, and tossed her head, and switched her train, and ogled and leered, and capered like the very Tostee herself, as seen through the reverse of an opera-glass. The child acted with spirit, or something that was like it, and seemed to have a morbid enjoyment and comprehension of the indelicate parts she played. The spectacle was far from being a pleasant one, and probably shocked more persons than it amused. Little Carmen was certainly not more than eight years old, and barely as tall as the table in her stage parlor, while none of the company reached in height the backs of the chairs of ordinary size with which, in strange incongruity, the stage of
