My Dear Sir,--It is not in my power to be present at the proposed demonstration in memory of the late Mr. Cooper. But I am glad of the opportunity, afforded by the invitation with which I have been honored, to express my regard for his name and my joy that he lived and wrote. As an author of clear and manly prose, as a portrayer to the life of scenes on land and sea, as a master of the keys to human feelings, and as a beneficent contributor to the general fund of happiness, he is remembered with delight. As a patriot who loved his country, who illustrated its history, who advanced its character abroad, and by his genius won for it the unwilling regard of foreign nations, he deserves a place in the hearts of the American people. I have seen his works in cities of France, Italy, and Germany. In all these countries he was read and admired. Thus by his pen American intervention was peacefully, inoffensively, and triumphantly carried into the heart of the European Continent. In honoring him we exalt literature and the thrice blessed arts of peace. Our country will learn anew from your demonstration that there are glories other than those of state or war. I have the honor to be, dear Sir, Your obedient servant, CHARLES SUMNER. REV. RUFUS W. GRISWOLD. * * * * * CHEAP OCEAN POSTAGE. SPEECH IN THE SENATE, ON A RESOLUTION IN RELATION TO CHEAP OCEAN POSTAGE, MARCH 8, 1852. This proposition Mr. Sumner constantly renewed at subsequent sessions of Congress. Mr. President,--I submit the following resolution. As it is one of inquiry, I ask that it may be considered at this time. _Resolved_, That the Committee on Naval Affairs, while considering the nature and extent of aid proper to be granted to the Ocean Steamers, be directed to inquire whether the present charges for letters carried by these steamers are not unnecessarily large and burdensome to foreign correspondence, and whether something may not be done, and, if so, what, to secure the great boon of Cheap Ocean Postage. There being no objection, the question was stated to be on the adoption of the resolution.
