under control. A deficiency of any one particular element 
will cause derangement, like an electric machine the battery 
must be properly supplied or we have no electric current, so 
with the nervous system, and, having already said that the ash 
of blood contains 54 per cent, common salt, it is reasonable 
to think that if blood requires so large amount of this valuable 
article for the establishment of healthy actions, that a want of 
it must cause disorder. The lands on which the complaint is 
mostly found having been robbed of the natural alkalies, the 
herbage in turn is deficient and does not reach mature 
development, aborting or seeding imperfectly before its time, 
consequently the animals grazing thereon suffer. And from 
the practical fact that Mr. Norman and Mr. Harker’s lands 
have been benefited by the application of salt, as well as from 
close observation I say fearlessly, that if these classes of lands, 
as well as wet, swampy pastures, were well dressed with this 
great natural and extensive agent, that Louping-ill and Rot 
in Sheep would soon be as things of the past. Therefore I 
say, let us follow the dictates of Nature, whose book is ever 
open, teaching us the right direction. u We are the appren¬ 
tices, she the mistress.” 
Let us then be up and doing, 
With a heart for any fate, 
Still achieving, still pursuing, 
Learn to labour and to wait.
