_. The province of New Brunswick, in 
British America, contains many millions 
of acres, frequently stretching down to 
the water’s edge, covered with forests, 
from which the best masts of the second 
size may be obtained in any number. It 
also abounds in coal and lime, and has 
inexhaustible mountains of gypsum, or 
plaister of Paris, an article made use of 
for manure in the United States, and the 
annual expenditure of which, where the 
farmers, from the exhausted condition of 
their lands, can scarcely obtain any crops 
without it, is declared on the most re- 
spectable authority to amount to up- 
wards of 150,000 tons annually. 
_ At the town of Carver, in the province 
of Massachusets, there is a pond, which 
contains such quantities of iron ore, that 
500 tons have been taken out of the wa- 
ter ina year. Upon the stream that runs 
from the pond is a furnace, and the iron 
made from this ore is mentioned as be- 
ing of superior quality. 
There were fifty sail of American ships 
in China Jast year, who took from thence 
to America from eight to ten thousand 
tons of tea, a great part of which finds 
its,wayto Europe. Canton isfullof Ame- 
rican adventurers, many of whom retire 
with large fortunes in a few years; there 
are at least a dozen who have been resi- 
dent for a year or two, and have already 
realized considerable sums. 
WEST INDIES. 
The total population of the Island of 
Trinidad amounted in 1797, (the time the 
‘Proceedings of Learned Societies: 
[Sept. 1, 
English took possession of it) to 17,718 
persons, of which number 2,151 were 
white people, English, Spanish, and 
French; 4,476 were Mulattoes, or peo- 
ple of colour,of diferent countries, French, 
Spanish, &c. 10,009 slaves, and 1,082 In- 
dians. ‘The proportion of whites was 
English, 610; Spanish, 505; French, 1,036. 
In the year 1801, the population bad in 
creased to 24,289, and in 1802, it was 
283477, of whom 2,261 were white peo~ 
ple, 5,275 free coloured people, 19,709 
slaves, and 1,232 Indians. 
In the island of Cuba neither wheat, 
olives, nor vines, are grown. Every ar- 
ticle of clothing is brought from Europe, 
there not being a single manufacture of 
any kind init. In 1792 there were ex~ 
ported to Spain, 80,000. cwt. of tobacco, 
besides that consumed inthe country and 
in America, The export of wax that year 
amounted to 5000 cwt. Bees have only 
been introduced into Cubasince the year, 
1764. After the peace of Versailles, 
when Florida was ceded to the English 
some families came over from St, Au- 
gustine, and brought some hives with 
them, and in a short time they encreased 
sowmuch that the sugar-plantations be- 
came eidangered. In this island there 
are six hundred sugar mills, from which 
more. than 500,000 ewt. of sugar was ex- 
ported to Europe. There is not one na- 
vigable river in Cuba, but only small ri- 
vulets and streams; there are one hun- 
dred and forty-eight lakes,-which contain 
fish, and there is abundance of turtle on 
the ecast. . 
PROCEEDINGS OF PUBLIC SOCIETIES. 
——S 
NATIONAL INSTITUTE OF’ FRANCE, 
REPORT of the TRANSACTIONS of the Ma- 
THEMATICAL CLASS Of the INSTITUTE 
in 1806, by M. DELAMBRE, SECRETARY 
to the INSTITUTE. 
O trace a rapid sketch of the la- 
T bours of the mathematical class 
to exhibit them in a few words, without 
however, omitting any thing that might 
deprive the authors of the esteem, or gra- 
titude which theyso well deserve ; to dis- 
play their discoveries in as plain language 
as possible; to clothe their dificult and 
abstruse researches in a garb, that may at 
Jeast render their importance evident, if 
-- it be impossible to detail their merit ; 
«such is the task, M. Delambre has under- 
taken, and which he flatters himself he 
has partly fulhiled. 4 
However valuable may have been the 
contributions this year in the department 
of the .natura! sciences, the zeal, we are 
informed, of the mathematical class has 
neither been less ardent, nor less success- 
ful. Even those of our associates, says 
M. Delainbre, who, from the fame of 
their long services had acquired a right to 
pass their days im tranquillity, have 
shewn their usual energy and activity. 
Thus respecting the new measurement 
of a degree in Lapland, when it was 
thought requisite to ascertain the cause of 
the error, which appeared to- have been —
