Leaves of the Maple 

 turned yellow, and begin 

 to fall. Leaves of the 

 Birch turned white, and 

 dead ; and about one half 

 of them fallen. Leaves 

 of the Ash, all fallen. 

 Leaves of the Pine, green 

 through the year. 



No leaves on the Ma-

 heat of the trees become 

 exactly the same with 

 that of the earth, at the 

 depth of ten inches be- 

 low the surface. 



From these observations it should seem, 

 that the temperature or heat of trees, is not the 

 same as that of the earth, or atmosphere ; but 

 is a heat, pecuhar to this class of bodies. It is 

 probably the same, in all trees of the same kind, 

 in similai' circumstances and situations. The 

 degree and variations of it, seem to depend on 

 the fermentation of the juices, and the state of 

 vegetation. It is not improbable the heat of 

 the same kind of trees, may be different, in dif- 

 ferent latitudes : Whether this is the case or 

 not, can be known only, by observations, made 

 in different countries. This heat v/hich prevails 

 in trees, seems to be the great principle or agent, 

 fey which the two fluids of water and air, are
