where the urine is directed to be applied, but 
mostly at a little distance from it. The sea- 
weed, I consider to be of as little value as the 
cow urine. In short, I may venture to say, that 
both the Recipes will be found to be of far more 
use as tillage than for the destruction of Cater- 
pillars.

as some erroneously believe, it w'ill be in vain, 
for, at this time, no Caterpillars exist. At this 
period the pai-ent is in search of a place to establish

there is a danger of the operation injuring the
