From William J. McAlpine, Engineer. 



1. A Plaster model of the United States Dry Dock, at Brooklyn. 



2. Fourteen specimens of granite, viz : 6 from Staten Island quarry, 



New- York ; 6 from Quincy quarry, Massachusetts ; and 2 

 from Blue Hill quarry, Maine ; being samples of the granite 

 used in the construction of the Dry Dock. 



3. A glass tube, hermetically sealed, containing specimens of the 



various soils through which the excavations were made, 

 stratigraphically arranged; with figures on the tube, indi- 

 cating the aggregate depth of the excavations, and the pro- 

 portional thickness of the different strata of earth excavated. 



4. A vial, containing earth, excavated at the depth of sixty-eight 



and a half feet. 



The Dry Dock at Brooklyn, taking into consideration the 

 strength, accuracy and beauty of workmanship, has been 

 pronounced, by competent judges, to be the finest piece of 

 masonry in the world. And the Engineers, not only of this 

 country, but of Europe, have justly denominated it the 



GREAT WORK OF THE AGE.
