The finer varieties of toilet sponge produce a high price, often 
as much.as forty shillings the pound weight for very choice specimens, 
a price which few commercial products obtain, and which prohibits 
their use, in short, to all but the wealthy. It is, therefore, very 
desirable that attempts should be made to carry out the submarine 
enterprise of M. Lamiral. With the assistance of the Acclimatisation 
Society of Paris, some experiments have already been made in this 
direction—so far without any satisfactory results, it is true, but every- 
thing indicates that by perseverance we shall see the enterprise 
crowned by the success it merits. 
In the Red Sea the Arabs fish for sponges by diving, the produce 
being either sold to the English at Aden or sent to Egypt. 
On the Bahama banks, and in the Gulf of Mexico, the sponges 
grow in water of small depth, The fishermen—Spanish, American, 
and English—sink a long mast or perch into the water moored near 
the boat, down which they drop upon the sponges; by this means 
they are easily gathered. 
The fine soft Syrian sponge is distinguished by its lightness, its 
fine flaxen colour, its form, which is that of a cup, its surface convex, 
voluted, pierced with innumerable small orifices, the concave part of 
which presents canals of much greater diameter, which are prolonged 
to the exterior surface in such a manner that the summit is nearly 
always pierced throughout in many places. This sponge is sometimes 
blanched by the aid of caustic alkalies ; but this preparation not only 
helps to destroy its texture, but also changes its colour. This sponge 
is specially employed for the toilet, and its price is high. Specimens 
which are round-shaped, large, and soft, sometimes produce very 
high prices. 
The fine sponge of the Grecian Archipelago is scarcely dis- 
tinguishable from that of Syria, either before or after being cleansed ; 
nevertheless, it is weightier, its texture is not so fine, and the holes 
with which it is pierced are at once larger and less in number. It is 
nearly of the same country as the former, in fact, the fishing for it 
extends along the Syrian coast as well as the littoral zone of the 
Archipelago and Barbary. 
The fine hard sponge, called Greek, is less sought for than either 
of the preceding ; it is, however, most useful for domestic and for 
certain industrial purposes. Its mass is irregular, it is of a yellowish 
colour ; it is hard and compact, and pierced with small holes. 
The white sponge of Syria, called Venetian, is esteemed for its 
lightness, the regularity of its form, and its solidity. In its rough 
state it is brown in colour, of a fine texture, compact and firm,.
