The Walnut is a summer theatre, and the least fashionable; and here it was my fortune to make my _debut_ to the Philadelphians with good success: a French company occupied at the same time the Chestnut, where, after a seven nights' engagement at the other house, I succeeded them; the proprietors being the same at both. These houses are large, handsome buildings, marble-fronted, having ample and well-arranged vomitories; and are not stuck into some obscure alley, as most of our theatres are, but standing in the finest streets of the city, and every way easy of approach: within, they are fitted up plainly, but conveniently, and very cleanly and well kept. I prefer the Chestnut, as smaller, and having a pit--as I think all pits ought to be--nearly on a level with the front of the stage, instead of being sunk deep below, looking, when filled, like a huge dark pool, covered with upturned faces. A crowded audience here presents as large a proportion of pretty, attractive women as are anywhere to be seen; and the male part is singularly respectable and attentive. Here again I must protest against the charge of insensibility being laid at their doors; that is, as far as my own feeling and experience goes. If by applause, a constant clapping of palms or hammering of sticks is only meant, interspersed with cries of "Bravo!" I admit they are deficient; but if an evident anxiety to lose no word or look of the artist, an evident abstraction from everything but the scene, with demonstrations of admiration discriminating and well applied, may be accepted as sufficient marks of approval, then has the actor no cause of complaint. With the tragedian, who strains after what in stage parlance are called _points_, and calculates on being interrupted by loud clapping before the sense of the sentence be complete, or else wants breath to finish it, a Philadelphian audience might prove a slippery dependence, since they come evidently to hear the author as well as see the actor, and are "attentive, that they may hear." For myself, the unreserved laughter in which they indulged I found abundant applause, and in well-filled houses the best assurance that they were pleased. The company here was a very good one, and the pieces as well gotten up as anywhere in the States. I paid frequent visits to this charming city, and shall have occasion again to refer to it. My first impressions are here set down, and favourable as these were, a more intimate knowledge only served to confirm them. JOURNEY TO BOSTON.
