Scarcity of cotton and the blockade.
--The manufacturers at the North are becoming embarrassed in their operations by the scarcity of cotton, and we notice that the New York Post, a great advocate of the war, is out in an argument in favor of raising the blockade, on the ground that its continuance will greatly injure the North and correspondingly benefit the South. The Harrisburg (Pa. ) Telegraph, another war journal, announces that work in the cotton mill at that place is to be temporarily suspended, owing to an advance in the price of cotton and difficulty in procuring sufficient supplies of the article.--The Conestoga Mills, at Lancaster, Pa. have already suspended for similar reasons. These suspensions are, we presume, what a Boston clergyman a few days ago exultingly called the ‘"blessings of war."’
