Moiccver, the grass was found to be the breeding place of the 
cutworm {Spodoptera exigua) for it was thickly infested with 
bodi adults and grubs of this pest. 
The results of the count after the lapse of one year were as 
follows. On Plots 1 to 3, no seeds germinated in the untreated 
grass.

The remarkably fast growth of Hilo grass during the second 
half year of the experiment reduced the percentage of original 
sowing of seedlings found at the end of the first half year in every 
case, ranging from as high as 10 per cent to as low as 5 per cent 
according to the different plots. 
The conclusion which may be drawn at the end of the first year 
of the experiment is that in a region such as this which is so 
favorable to the rapid growth of the grass, little may be expected 
in shading out the grass by attempting to establish a stand of 
haole koa by sowing after burning the grass or after burning it 
and digging up the ground. 
It is possible, however, that the remaining seedlings will sur- 
vive long enough to overtop the grass and as a thin and scattered 
stand eventually attain this end. For this reason, the plots will 
be kept under observation for another two years.
