~ EXPERIMENTS WITH TREE SEEDS, Loi 
growth, the effect on the plant of the original position of the seed 
is still conspicuous. In Fig. 1, which shows three typical plants 
produced by acorns placed with the thin end lowest, the stem 
and root are in a straight line, so that no curve is noticeable at 
the base of the former as a result of its having to find its way 
round the fruit, In Fig. 2, which shows plants that originated

thick end lowest. 
in acorns placed with the thin end uppermost, a distinct twist 
is apparent at the junction of the root and stem, the former 
having had to bend itself round in order to get down. Where 
the acorns were laid flat there is also a slight twist upon many of 
the resulting plants (Fig. 3), though this is not so pronounced as 
in Fig. 2. 
When three years old, the whole of the plants were lifted, great 
care being taken to get the roots out fairly entire. The length of
