ELEMENTS OF AGRICULTURE. 
13. The life of animals and vegetables exhibits a differ¬ 
ence worthjr of remark ; it is that vegetables seem to be 
endowed with the reproductive power in all their parts. 
Thus, when the limb of a tree is cut off and planted in the 
earth, it may produce another tree. This is not the case 
with animals. 
14. Minerals, and other brute bodies, united in large 
masses in the bosom of the earth, form rocks that are in a 
continual state of decomposition. The particles derived 
from this decomposition constitute, by their mixture with 
organic remains, the different species of soil that are culti¬ 
vated. In other words, soils are composed of a mixture 
of organic and inorganic remains.
