384 Beet-Root.—Discovery of Haine. 
in a short time evaporates the water, and the salt is left in the 
sand, which is scraped up and put into raised reservoirs of ma- 
sonry about six feet by four, and five deep. When the receiver is 
full of the sand, sea water is poured on the top; and this, in its 
way down, carries with it the salt left by the evaporation. When 
it runs out below at a small hole, it is a very strong brine ; this 
is reduced to salt by being boiled in vessels about three feet wide 
and one deep. ‘The cakes resulting from this operation are an 
inch and a half in thickness. 
SUGAR OF THE BEET-ROOT. 
The endeavours that were made in France, during the war, 
to produce sugar from the beet-root in sufficient quantity to sa- 
tisfy the demands of the population, were very successful, and it 
was procured of excellent quality. The peace however, by re- 
opening the ports, and allowing the introduction of the cane- 
sugar, tended to paralyse that branch of agricultural industry, for 
which, however, some strong exertions have since been made 
by the philosophers of France. 
The following is given as the statement of the expense and 
returns of the manufactory of M. Chaptal; and if there are no 
unstated objections to its introduction, it is difficult to account 
for the preference given to cane-sugar. , 
Forty-five French acres were sown with beet-root; the pro- 
duce equalled 700,000Ibs.

DISCOVERY OF HAUYNE IN THE ISLAND OF TIREE. 
Hitherto in Scotland the attention of mineralogists has been 
principally directed to the investigation of the structure, relative 
position, and mode of formation of mountain rocks. This branch 
of mineralogy, it must be confessed, is more generally interesting 
than
