MY DEAR SIR:--My occupations in the country prevent my attendance in town at the meeting of the committee, but I am anxious to know what is doing. I signified at our first meeting what I thought the best monument to the memory of Mr. Cooper--a statue. It is the simplest, purest, and most satisfactory--perpetuating the likeness of the person. I understand there is an excellent bust of Mr. Cooper extant, made when he was in Italy. He was there in his prime; and it might furnish the model for a noble statue. Judge Duer suggested that his monument should be placed at Washington, perhaps in the Smithsonian Institute. I was rather for New-York, as he belonged to this State, and the scenes of several of his best works were laid in it. Besides, the seat of government may be changed, and then Washington would lose its importance; whereas New-York must always be a great and growing metropolis--the place of arrival and departure for this part of the world--the great resort of strangers from abroad, and of our own people from all parts of the Union. One of our beautiful squares would be a fine situation for a statue. However, I am perhaps a little too local in my notions on this matter. Cooper emphatically belongs to the nation, and his monument should be placed where it would be most in public view. Judge Duer's idea therefore may be the best. There will be a question of what material the statue (if a statue is determined on) should be made. White marble is the most beautiful, but how would it stand our climate in the open air? Bronze stands all weathers and all climates, but does not give so clearly the expression of the countenance, when regarded from a little distance. These are all suggestions scrawled in haste, which I should have made if able to attend the meeting of the committee. I wish you would drop me a line to let me know what is done or doing. Yours very truly, WASHINGTON IRVING. The Rev. RUFUS GRISWOLD. The plan thus recommended by Mr. Irving will undoubtedly be approved by the committee and the public, and there is little doubt that it will soon be carried into execution.
