With regard to the material of which monuments may be constructed with a view to durability, it is acknowledged that the best sandstones are every way suitable. They should be made of the compact, fine, light colored kinds, in order that they may be easily worked into form as sharp and delicate as marble itself. The stains of weather, and the falling of leaves, would not disfigure them. Granite we have already indicated, but Bronze is better adapted to statues and reliefs, as well as to vault entrances, than any other substance, and is as enduring as could be desired. In Greenwood Cemetery, New York, there are several good examples, especially the monument to De Witt Clinton, executed by Brown, an excellent artist of that city, who works in bronze equal to any European. Effigies are particularly suitable in this material, and we hope to see it much more generally employed, as it unquestionably will be; this is the enduring and yet plastic material so much wanted.

As it is not to be expected, however, that we shall very soon give up the best marble, this should be protected by a canopy or temple. In the continental cemeteries, it is usual for a portion of the ground to be appropriated for sculpture, by the erection of covered ways for numerous families who patronize the fine arts; such may be seen at Frankfort on the Maine, where we especially remember the temple of the Bethman family, occupied by some of the finest statuary of Thor-walsden.

While we write, a very sensible little volume has been laid on our table, entitled "Hints concerning Greenwood, its Monuments and Improvements, by N. Cleveland," from which we make a few brief extracts to the point: -
