 degree of moifture neceffary for the pine 

 might injure the neighbouring coffee— the

 exact proportion required by the cotton — or 

 the precife ratio of light and heat might 

 differ from that demanded by the fugar cane ! 

 But where man commands thedifpofal he may

 the natural climate, may learn to cultivate, i
