acridity of this plant is possessed, in commo 
the Zroidez ; and from its saponaceous quality, it has been 
used in washing, instead of soap ; the acridity of it, how- 
ever, unless carefully washed away, chops the hands of 
the laundresses. When thoroughly washed from the root, 
and a similar process pursued as in making starch, it 
yields a fine amylum. This is made into 4 sago by the 
_ inhabitants of Portland Island, where it is abundant. I 
suspect that some of the varicties of sago, in our shops, 
are obtained thence.
