A merchant of this city, some ten days since, wrote

to General Cass, suggesting a method by which a satisfactorrarrangement could be made With Great Britain for inquiring into the nationality of suspicious vessels. He recommended that an American lieutenant should be placed on board of every British cruiser and that a British lieutenant should be placed on board of every American cruiser, on the look out for slavers ; and that any suspected vessel should be visited, and her papers examined by the officer whose national flag she might carry. In this way, it was believed, all feelings of national honour and pride might be respected, and the ends of a vuat attained without any possibility of national offence. The suggestion Is Certainly worthy of consideration.—New York Times.
