54 STUDIES OF NATURE. 



cies, by d.Tcovering to ns the admirable correfpon- 

 dency which they have, in every latitude, with the 

 Sun, the Winds, the Water, and the Earth. 



On this plan, we have a glimpfe of the light 

 which Geography may diffufe over the ftudy of 

 Botany j and of the light with which Botany, in 

 it's turn, may illuminate Geography ; for,- fup- 

 pofmg we were enabled to form botanical charts, 

 in which, by colours and figns, fliould be repre- 

 fented, in each particular country, the reign of 

 each vegetable there produced, by determining it's 

 centre and limits, we might perceive, at once, the 

 fecundity proper to each diftriâ;. This knowledge 

 would fupply very ample means of rural economy, 

 as we might fubftitute to the indigenous plants 

 which were there in greateft abundance, and moft 

 vigorous, fuch of our domeftic plants as are of the 

 fame fpecies, and which would there infallibly fuc- 

 ceed. Befides, thefe different claffes of vegetables 

 would, in their various natural arrangement, indi- 

 cate the degrees of the humidity, of the drinefs, of 

 the cold, of the heat, and of the elevation of each 

 diftriâ;, with a precifion which our barometers, 

 thermometers, and other phyfical apparatus, can 

 never attain. I omit a multitude of other relations, 

 produftive of pleafure and of utihty, which would 

 refult from fuch claffification, but which I fhall en- 

 deavour to unfold in their place.
