This building, which occupies the space between Centre, Elm,
Leonard, and Franklin streets, is a unique and beautiful specimen of
the Egyptian style of architecture. Ills 253 feet long, and 200 feet
wide. The front is entered by eight steps, leading to a portico of
four massive Egyptian columns. The windows, which extend to the
height of two stories, have massive frames, and cornices ornamented
with the winged globe and serpents. The two fronts on Franklin and
Leonard strei.-fs have each two entrances, with two massive columns
each ; and the back entrance forms a carriage way, for taking pri¬
soners to and from the house of detention. This building, though
handsome of its kind, has a heavy and gloomy aspect, which has ac¬

a light-colored granite, from Hallowell, Me.

The Court of Sessions occupies a part projecting back from the
front building, the roof of which is supported by lofty Egyptian
columns.
