&c. An Effay on the beft Plan of a prac- 
tical School of Agriculture, &c. &c. by 
K.G. RAFN, 1798. 44 fheets, 8vo. In 
evety ftate in which agriculture yet ftands 
in need of many important Improvements, 
this objeét undoubtedly can be obtained 
by no better means than by a particular 
inftitution, in which young people receive 
theoretical and praétical inftruétions in the 
proper management of hufbandry, and by 
fending them afterwards back again to 
their families,toapply and to propagate their 
knowledge and experience among their 
fellow-citizens. The prefent treatife,which 
obtained the prize of the royal fociety of 
{ciences at Copenhagen, which propofed the 
queftion: What ought to be taught in fuch 
an inftitution, and what would be the heft 
method of inftruction? delineates a moft 
excellent plan for fuch an agricultural 
academy. he learned author propofes, 
Literature.,,Occonomy. 557 
that the country people fhould be enabled, 
by judicious principles, deduced from ex- 
perience, to increafe and to ameliorate the 
produces of the country, and for thar pur- 
pole fhould be fufficienrly initiated in the 
fundamental principles of natural philo- 
fophy, natural hiftory, chemiftry, and ma- 
thematics; to which we fhould add, a 
knowledge of the moft common difeafes 
of cattle, and of the beft method of curing 
them. The method of inftruétion which 
he propofes is extremely appropriate, but 
cannot be fpecified here for want of room. 
We only obferve, that his propofals de- 
ferve ferious confideration; and that in- 
ftitutions formed after Mr. R.’s plan 
would be highly beneficial to any coun- 
_try.

matter for ferious confideration: It con- 
tains feven eflays, treating on the deftruc-

The German chemifts have of late years 
made various attempts to prepare fugar 
from the juice of inland plants. MarGg« 
GRAF, an eminent chemift of that inge- 
nious nation, was the firft who produced 
a beautiful loaf-fugar from the juice of 
carrots; but this invention was not profe- 
cuted any further, on account of its being 
dearer than that imported from the Weft- 
. Indies, and the juice was ufed only in fome 
places, boiled down to the thicknefs of . 
honey. Afteréhe foundation of the Ame- 
rican republic, the cultivation of the maple- 
tree was introduced in Pruffia by Mr. von 
Burcsporr; and prof. HERMSTAEDT 
prepared of its juice, as well as of that of 
the acer platanoides, and the accr pjéudo- 
platanus, Linn. a beautiful white fugar, 
which he, however, was not capable of 
divefting of an wnpleafant tafte, which 
rendered it rather unpalatable. Mr, 
BRAUMNELLER made feveral experi- 
ments, on a large fcale, to extraét {ugar 
from wheat, in which he fucceeded ; but 
could not bring his fyrup to a proper con- 
fiftency. Mr. ACHARD, of Berlin, was
