MAY 26TH.—Gen. Lee is still strengthening the army. Every day additional regiments are coming. We are now so strong that no one fears the result when the great battle takes place. McClellan has delayed too long, and he is doomed to defeat. The tobacco savers know it well, and their faces exhibit chagrin and disappointment. Their fortunes will not be made this year, and so their reputations may be saved.
