26 Forty-second Annual Report on the 



twenty-seventh, I did write such a letter, of which I append a 

 copy, together with the reply to the same : 



New Albany, Ind., October 27, 1888. 

 To the Trustees of the Sherman Free Library, Port Henry, Essex county, 

 N. Y. : 



Gentlemen. — Professor Benedict has informed me that there is a 

 flag of the Potsdam sandstone, in the sidewalk in front of the Free 

 Library Building, which contains the tracks or trails of some marine 

 auimal, and which I would like to secure for the State Museum of

 with you for the exchange of that slab for another of equal size and 

 quality, and have the new one put into the walk free of expense to 

 the Library. I hope the Trustees may be willing to accept of this 

 exchange and thus confer a benefit upon the State Museum of Natural 

 History. 



Very respectfully. 



(Signed,) JAMES HALL, 



Director of the State Museum.

Respectfully yours, 



(Signed,) F. A. PRICE, 



Secretary.

 an acknowledgment to the local freight agent at Port Henry, who 

 very kindly placed a car upon the switch at our disposal. The 

 flag from the sidewalk and those directly quarried from the rock, 

 were delivered in Albany on the twenty-fourth of November. The 

 flag-stone from the sidewalk above referred to, which is about 

 four feet square, is now exhibited in the area adjoining the
