must not be supposed that laying the salt or lime 
upon the surface of the ground will answer the 
end, without its falling upon the Worms. Some 
of the supporters of the salt system would make 
it appear that where salt is used it will not only 
serve for tillage, but prove of essential service for 
the destruction of various kinds of insects; cer- 
tainly, as I said before, it will destroy Worms, and 
also Slugs, Snails, and Slug-Worms, but it must 
alight fairly upon them. I feel persuaded, however, 
that I state the very extent of its merit, on that head, 
for no other vermin, that I know of, that is injurious 
to vegetation, will be destroyed, though it should fall 
fairly upon them ; therefore any random, or indis- 
criminate salting of land, without there is some- 
thing more important in view than destroying of 
vermin, would be a waste of both salt and 
time. 
When Worms are neglected, at the time of 
digging, their mischief may be greatly decreased 
by dusting the surfaee of the infested ground as 
often as it may be deemed necessary, with No. 
14 ; each dusting may be applied as thin as pos- 
sible, but when the weather is wet it will require 
doing the oftener, as the efficacy is destroyed by 
wet, or the earth may have a good watering through 
a coarse watering-pan rose with the Mixture, 
(No. 15) which will effectually destroy them, at 
seasons when they are not too deep in the earth, 
viz. in the evenings and mornings of the spring 
and autumn months, and in wet summers. By
