YANKEE SPIES. – We are informed that the paragraph from the Petersburg Express, relative to a Yankee spy having been seen in the city, copied by us yesterday, is true, except that the place at which he was seen was the Exchange, and not the American, and in the Parlor instead of at the Dinner table. His name is Dennis, and in Washington he was Seward’s chief detective. He was recognized by the little daughter of Mrs. Greenhow, who had been instructed by her mother, while in Washington, to make herself familiar with the facts of such characters. The shrewd rascal, it seems, recognized the little girl, at the same time that she discovered him, and when she ran to give the intelligence to her mother he disappeared. The fellow is remarkable for his cleverness and cunning, and has no doubt before this put McClellan in possession of much that he desired to know. The event should be an admonition to our own detectives and guards – and to the people generally. Let all be on the qui vive, and let every person who has the least atmosphere of doubt about him be required to give an account of himself.
