On the present occasion it may be noted, at once to complete the picture and give additional insight of a character which did very independent and _outre_ things, that Tom Leslie had gone to Niblo's with his carefully-dressed and precise friend Harding, and sat conspicuously in an orchestra chair, in a gray business sack, no vest and no pretence at a collar. In other men, Harding would have noticed the dress with disapprobation: in Leslie it seemed to be legitimately a part of the man to dress as he liked; and neither Harding, or any one else who knew him, paid any more attention to his outward appearance than they would have bestowed upon a harmless lunatic under the same circumstances. Wherever Leslie boarded, (and his places of boarding were very numerous, taking the whole year together,) it was always noted that he filled up the hat-rack with a collection of hats of all odd and rapid styles, with a _few_ of the more sedate and respectable; and on this evening's visit to Niblo's, when there was not a shadow of occasion for a hat with any brim whatever, he had completed his personal appearance by a fine gray beaver California soft hat, of not less than eighteen or twenty inches in the whole circumference, which gave him somewhat the appearance of being under a collapsed umbrella, and yet became him as well as any thing else could have done, and left him unmistakably a handsome fellow. An oddly mixed compound, certainly--even odder than Harding; and yet what a dull, dead world this would prove to be, if there were no odd and _outre_ characters to startle the grave people from their propriety, and throw an occasional pebble splashing into the pool of quiet and irreproachable mediocrity!
