withering, the haustorm were smaller and less numerous, and secondary 
and tertiary rootlets were fewer and shorter. 
It may not be out of place to mention that in numerous cases of 
young thread-like rootlets of sandal seedlings and of their hosts the haus- 
toria were found developed on the sandal rootlets themselves even when 
actual attachments had occurred, instead of on the hosts rootlets as 
generallv occurs in more developed and thicker rootlets : in some instan- 
ces, thin rootlets of host plants were found trailing along those of the 
sandal and firmly fixed to them at some points without any visible 
haustoria being formed at such points, while in others the sandal rootlets 
trailed along those of the hosts.

9. On the 19th July 190G, two dealwood boxes A and B were di- 
vided into two equal compartments by fixing a plank vertically in the mid- 
dle. In box A, one compartment was filled with sand and the other with 
loamy friable soil from the nursery. In the former 18d sandal seeds and 
In the latter 130 were sown. In box B one compartment was filled 
witti sand and the other with loamy soil : the former was sown with 200 
sandal seeds and 200 Dirsanam {Alhizzia Lebbek) seeds, and the latter 
with 200 sandal and 200 Kanuga seeds [Pougamia glabra). 
In both the boxes and in all the compartments germination of sandal 
was observed on the 16th of August. On the 29th of September, there 
were sandal seedlings in the sand and .8 seedlings in the soil compart- 
ments of box A ; in box B, there were 30 sandal seedlings in the compart- 
ment sown with Kamiga and 36 sandal seedlings in the other. The 
Kannga and Dirsanam seedlings which had also germinated were not 
counted. The sandal seedlings in all the compartments were alike in 
their vigour and appearance in September 1906. 
On the 16th of March of the following year the heights of the 
seedlings were measured and the following notes recorded : —
