 rivulets be one, two, or more miles, below the 

 fpring-head. Nor is there a moment's doubt but 

 that at a very confiderable diftance below, there

 higher up, but not in general; the variety of foil, 

 (for fome may be found better there than at the 

 fpring-head) and other local circumftances, I pre-

 water, at the fame time, will have different effects

 ftreams, or rivulets, into three divifions.
