in the control and treated halves of the beds. The transplants, 
however, provided striking results after ten weeks, inasmuch as it 
was apparent that the root-pruned plants were dead and dying 
in a distinctly greater degree than the non-root-pruned plants. 
In the control half of the Jzal-treated bed where all the transplants 
had been root-pruned, all the plants were dead, and in the treated 
halves of both beds the root-pruned plants were long dead while 
the alternate non-root-pruned plants were only sickening. 
non-root-pruned plants in the control area of the Fungal treated 
bed were in the same condition as the non-root-pruned plants 
of the treated areas. Representative plants were taken for 
examination, and the Fusariwm was recovered from all. Sections 
of roots showed no differences from previous preparations. There 
was no distinction in kind or degree of disease between plants from 
the treated and control areas. It was concluded, therefore, that 
the Izal and Fungal treatments were quite ineffective and that a 
set back to the Grevillea seedlings in the form of transplanting 
operations was sufficient to ensure a parasitism of the Fusarium 
which varied in virulence according to the treatment of the 
plants, for the addition of root-pruning to transplanting ensured 
one hundred per cent. deaths. A series of cross inoculation 
experiments with the Fusarium from cashew nut, Grevillea and 
loquat is described below 
THe FusARIuM ON EUGENIA JAMBOS SEEDLINGS. 
A bed adjoining the two Grevillea beds referred to above had 
been filled with transplanted rose apple seedlings in rows, and 
it was found that they also were dying off in time. The number 
of deaths was never more than a small percentage of the number 
of plants, whereas in the Grevillea beds the deaths approached 
one hundred per cent. The symptoms of disease were exactly 
Similar to those found in the Grevillea seedlings, and micro- 
preparations showed a like infestation of hyphae. No conidia 
were seen within the tissues and chlamydospores were scarce. 
the development of the Fusarium, and root-fragments in culture 
media were fertile of Fusarium in nine out of ten cases. It 
seemed, therefore, that here was another case of the parasitism 
of the Fusarium ‘but in a further reduced form. The HLugenia 
seedlings had been root pruned and were on that account more 
open to the entrance of the Fusarium into the roots, but the 
number of cases of attack was small. This species apparently 
possessed an immunity denied to the silky oak and the cashew 
nut.

At the same time, a few seedlings of loquat in a near by 
bed were observed to wilt. They also had been transplanted,
