Under fair conditions each leaf of a young tree grows decidedly more 
rapidly than the next older one, and in seedlings which are of the size of 
the ones mentioned above, several leaves grow rapidly at the same time. 
While the plants represented in this table were under observation the 
growth of their roots was prevented by frequent moving. This injury 
was reflected by a slower development of the shoot before the measure- 
ments ceased. Each leaf had less than the normal advantage over its
