42, ASCERTAINING THE COMPONENT PARTS 
OF ARABLE LAND. To the person who shall 
“produce to the Society the most satisfactory set 
_of experiments to ascertain the due proportion 
_ of the several component parts of rich arable land, 
in one or more counties in Great Britain, by an 
accurate analysis of it; and who having made a 
like analysis of some poor arable land, shall, by 
comparing the component parts of each, and 
thereby ascertaining the deficiencies of the poor 
soil, improve a quantity of it, not less than one 
acre, by the addition of such parts as the former 
€xperiments sH&ll have discovered to be wanting 
therein, and therefore probably the cause of its 
‘Sterility; the gold medal, or forty guineas. It 
required that the manurings, ploughings, and 
trops, of the improved land, be the same after 
_ the improvement as before; and that a minute

575 
tificates and the chemical results of the analysis, 
which are to remain the property of the Society,

1803.° : 
It is expected that a quantity, not less than 
six pounds, of the rich, of the poor, and of

the gold medal, or thirty guineas. 
44. For the next greatest quantity, not less 
than thirty acres, the silver medal, or twenty 
guineas. It is required that the land before such 
improvement be absolutely uncultivated, and in 
a great measure useless, and that, in its improved 
state, it be enclosed, cultivated, and divided 
into closes. Certificates of the number of acres, 
of the quality of the land so improved, with a 
full account of eyery operation and expense at-

average-value thereof, to be produced on or be- 
fore the first Tuesday in February, 1803. 
45, Mawnures, For the most satisfactory set 
of experiments, to ascertain the comparative ad- 
vantages of the following manures, used as top-

any other fit article; the gold medal, or the 'sil-
