he north and south of Commerce Dock, parallel
with Orleans Wharf on the one hand and Lamblardie Wharf on the other.

The northern gallery is connected by a foot bridge with the annex of
Commerce Place, where is located the colonial exhibition, the center of
which is occupied by a Cambodian pavilion, in which are brought together
the products of Indo-China and Algeria. For half of their extent, the two
galleries are separated from the dock by a promenade provided with seats
and covered with a roof. On this promenade, it became necessary to make
room for certain belated exhibitors whose products are not affected by the
open air.

In Commerce Dock are to be seen, floating, specimens of every ancient and
modern naval construction, French and foreign, among which are the state
convette Favorite and an English three-master converted into a cafe boat.
We find here, too, the giant and prehistoric oak of the Rhine, on board of
the Drysphore.

Commerce Dock is divided into two parts by a foot bridge, which allows the
visitors to pass from one side to the other without being compelled to
tiresomely retrace their steps.

The main entrance to the Exhibition is opposite the portico of the theater,
on Gambetta Place. A second entrance is found on Commerce Place in the
colonies annex. The others, near the center, are on Orleans Wharf, opposite
Edward Larue Street, and on Lamblardie Wharf, opposite Hospital Street and
opposite Saint Louis Street.

The garden of the Exhibition and the galleries that surround it are
illuminated at night by the electric light.--_L'Illustration._

OUR COAST DEFENSES.

General H.L. Abbott delivered a lecture before the Academy of Sciences in
New York, on the evening of March 21, a summary of which is given by the
_Herald_ as follows:

According to General Abbott, the country needs for its coast defenses:

Heavy guns;
Armor-clad casemates;
Disappearing gun carriages in earthworks;
Heavy mortars;
Submarine mines or fixed torpedoes; and
Fish torpedoes.

The lecturer said that this nation may be attacked in four ways: First, by
fleet and army combined, as in our revolutionary war; second, by blockading
the entrances to all our ports; third, by bombardment of our seaport cities
from a long distance; fourth, by a fleet forcing its way into our harbors,
and making a direct attack or levying tribute on our people.
