Transplanting older seedlings. — In August, 1910, six additional 
rows were set with plants which had been left in the nursery a year 
longer than those in the previous experiment. The average plant 
had from two to four pairs of branches. The manner of transplant- 
ing was the same as that of the year previous. The trees for row 4 
were removed from the nursery with a large ball of earth. The in- 
creased extension of the root system necessitated the clipping of some 
roots. The plants of rows 5 and 6 were set with roots bare of earth, 
those of row 5 severely cut back, and of row 6 as nearly intact as 
possible. On one hillside the trees of these three rows had the leaf- 
age reduced by cutting away one-half to two-thirds of each leaf, but 
this leaf pruning showed no measurable effect on the growth at the 
end of a year, the two groups varying only 0.4 inch in average 
height per tree. 
The root treatment of rows 7. 8, and 9 corresponded to that of 
rows 4, 5, and 6, respectively, but their stems were all cut at a height 
of 4 to 6 inches. 
As the root pruning given rows 2. 5, and 8 was due to an abnormal 
condition, these rows should be considered in a separate group. In 
transplanting older seedlings in these tests, and in other instances 
since, it has been observed that many trees with a badly twisted tap- 
root will send down a strong, straight root from above the twist, 
thus remedying the trouble without aid. The very radical prun- 
ing of rows 7, 8, and 9 also puts these rows in a class to themselves. 
Two months after setting all rows looked thriftier than those with 
severely pruned roots. Most of the stumps of rows 7, 8. and 9 had 
developed shoots 2 inches high. At 4 months after setting the trees 
which had been transplanted with a ball of earth looked more vigor- 
ous than those in the corresponding rows set with trees with bare 
roots.
