about to furnish the necessary funds for 
this interesting undertaking, and to super- 
— the operations.

A Brussels journal announces, that 
among the productions of industry which 
will be sent from Western Flanders to the 
exhibition at Haarlem, is a piece of cloth 
which has in its breadth 4,200 threads, so 
fine, that they cannot be discerned without 
-a magnifying glass. This piece was spun 
and woven by a brother and sister. ~ There 
is also a spindle of thread, imperceptible 
through fineness, which is valued at 400 
Dutch florins.

* Iverdun.—Steam navigation haying be- 
come so successful on the great lakes, it is 
determined to introduce it on the second 
and third class of lakes; and, for this pur- 
pose, a vessel is in preparation. This may 
be considered quite an enterprize, as the 
communication is interrupted by small 
rapids, and in many places the depth is 
insufficient. Some difficulty will occur in 
removing these obstacles ; but measures are 
taken to lend every assistance towards the 
completion of the work. 
, Lausanne.—It is said that a junction 
between the Lakes of Geneva and Neuf- 
chatel is to be formed. Should this be car- 
ried into execution, it will be of great con- 
sequence to France, Switzerland, and the 
adjacent provinces. It is curious, that 
Napoleon, when First Consul, in 1803, 
contemplated this enterprize. It will open 
a communication, by water, from the Medi- 
terranean to the Baltic.

The budget of this kingdom for the year 
1824, allows to: the University of Chris- 
tiana an annual sum of 35,000 species, 
payable out of the public treasury. Of 
this sum,°7,500 species are devoted to the 
library of the University, 400 to the pur- 
chase of astronomical instruments, and 
600 to the expenses of scientific travels 
and researches in the interior of the coun- 
try- Independent of this fund, the Uni- 
versity possesses a fixed annual revenue 
- 15,000 species.

HAITI. f 
The Haitians, in order to show their 
esteem for the memory of M. Delille Laprée, 
have republished his works. In a discourse 
pronounced before the National Lyceum, 
of which he was the Director, he enume- 
rated the advantages which had resulted 
from the various schools and societies of 
learning and art established in Haiti, more 
particularly the National Lyceum. He 
627 
concluded by admonishing the young Hai- 
tians to give themselves up to study, but to 
love their country above all things, and show 
that nothing is impossible to the sons of 
Africa ; and though Haiti, by its consti- 
tution, had put a check upon the warlike 
spirits of its sons, by itself assigning the 
ocean for its limit, there was no obstacle 
against their aspiring to a softer and more 
durable glory—the conquest of the Arts 
and Sciences ; and, with them, the respect 
and admiration of the world. There are 
also several poems by the same author. 
c AMERICA, 
The gold mines of North Carolina, be- 
tween the 35th and 36th degrees of north 
latitude, and the 80th and 8lst of west 
longitude, on the southern side of the state, 
are spread over a space of not less than 
1,000 square miles; in almost every part 
of which region, more or less of this pre- 
cious metal may be found, at or near the 
ground: but its true bed isa thin stratum 
of gravel, enclosed in pale blue, but some- 
times yellow mud. Rocky rivers and tri- 
butaries, cutting through this stratum 
(which varies from three to eight feet in 
thickness), prove the most fruitful lo- 
calities. ‘Che prevailing rock, in the gold 
country, is argillite, which has been sup- 
posed to be the peculiar repository ef the 
metal ; but further examination has proved 
it to extend beyond the slate, over a region 
of granite and gneiss. The country is 
barren and unfruitful, and the inhabitants 
mostly poor and ignorant. The principal 
mines are—Anson Mine, Reed’s Mine, 
and Parker’s Mine. If we suppose gold- 
dust derived from diluvial action on masses 
of the same métai, two well-known’ facts 
will be readily explained—the general dif- 
fusion of gold-dust in the sands of different 
countries—and the circumstance, that many 
anciently auriferous rivers are so no longer. 
Of these we may mention the Tagus, the 
Po, the Pactolus, and the rivers of France, 
which appear, heretofore, to have been 
more so than now. The dust derived from 
diluvial action may be conceived to be 
exhausted, or washed away, in the course 
of ages. 
Oolite, which was thought not to occur 
in situ in North America, unless, perhaps, 
in the Ohio district, has been very distinctly 
characterized by Dr. J. H. Steel, of Saratoga 
Springs, in the New York state. It is 
composed of black grains, included in a 
grayish basis. A farmer brought the spe- 
cimen, as large as a man’s hand, saying he 
had picked it up on his farm, and that it 
contained “ Petrified Mustard Seed,”*
