The plantain bears at 1,529 yards, in a temperature of 61 deg. 

 Pahrenlieit, and requires fifteen months, but its cultivation 

 is of little benefit in so high a latitude. It is the same with the 

 cassava root. The cane at 1,160 altitude, in a temperature of 66 

 deg., gives no sugar ; and indigo at 1,620 aflbrds no coloring 

 matter.
