out on the same dates as those in the above plates. Careful examination 
with a lens of the network of rootlets shows some root-attachments 
between the '2 species, but they are not so numerous as in the other cases ; 
one of the teak seedlings sickened and was withering when removed 
from the tiles pots. The sandal seedlings in both specimens were healthy 
though not quite so vigorous and rapid in growth as those grown with 
Kanuga or Odesa. s. h. — Sear of Haustorium. 
Plate IX. — Specimens of 2 sandal seedlings growing together pure 
in one tile-cylinder. Their roots have mutually attacked each other and 
formed connections at several points starting from a of the seedling on 
the right-hand side. Note the scanty and short development of the 
secondary and tertiary rootlets as well as the shortness of the tap-roots 
of both seedlings compared with those grown with other species of plants 
(Plates IV to VIII).

12. Sumwary of the results gathered from the foregoing experiments. 
1 . Sandal seed appears to lose its vitality in about a year and 
apparently does not germinate after this period. (This point requires 
further investigation and confirmation as it is based on only one experi- 
ment.) 
2. It generally germinates in about a month after sowing and 
germination may continue up to 3 months and even later. 
3. The seed-bed should be well drained as otherwise stagnant water 
will cause the seed to rot more easily than in manv other species. 
4. The young seedling is nourished and developed almost solely by 
the reserve material in the seed in its early stage : the reserve material 
is transferred quickly to the hypocotyl from the cotyledons, which, 
however, persist for a long time (0 months or more) on the young stem, 
unless destroyed by vermin as often hajrpens. 
5. Sandal seedlings aie incapable of growing beyond a year at the 
most unless nourished by root-attachments to roots of other plants 
without which they turn pale, wither and die out within a year of 
germination. 
6. Young seedlings establish root-attachments with other plants at a 
very early age - when less than even 2 months old. (Examination of the 
roots of a number of young sairdal seedlings with a strong lens showed 
that root-hairs aird root-fibres which are the chief organs of absorption
