third was added to the crop, when the 13 loads were assisted by 3 
cwt. of guano, or 7 cwt. of woollen rags ?* Had Mr. Pusej's mind 
been disembarrassed of other cares, would he not have followed 
up in after years ihese curious results by other experiments, fitted 
to test their truth, and to explain how they were brought about? 
For carrying out such experiments with such views, has any 
provision hitherto been made ? I know of none. I do not say 
this by way of reproach to ourselves, since so far as I know, no 
such provision has hitherto been made in any country. Model 
farms, which in many places exist, have not hitherto contemplated 
this as one of their objects. But it appears to me that the science 
of agriculture is now retarded by the want of more sure means of 
interrogating Nature in the field, as well as in the laborator}'. It 
is something for us to be the first to recognise this position of 
things, and to cast about for means by which the obstacle may be 
removed. 
And how is it to be removed ? By what union of will and 
purpose are land and money, the first requisites, to be obtained? 
and afterwards, a head secured, to devise experiments which shall 
lead to definite and useful ends, and hands fitted carefully and 
accurately to perform them ? 
In England, where men unite together so readily for every 
useful object, the answer to these questions ought not to be very 
difficult ; but as it is not my present purpose actually to incite 
you to exertion in favour of any definite proposition, I content 
myself with indicating what ought to be, and I am sure by and 
by will be done, in various parts both of England and America. 
The suggestion I have ventured to make is certain to be gravely 
considered by the fiiends of agricultural improvement. 
Second. A second point, connected in some degree with these 
field experiments, and the im])ortance of which is very obvious, is 
to train up and encourage a race of instructed, conscientious, and 
honourable manufacturers of artificial manures. This is a matter 
which really concerns the pockets of all practical men, and it is 
in their power very much to bring about the desired end, by 
ceasing to purchase what is merely low in price, and attending 
more closely to what is good. In addition to the good faith of 
the maker and dealer, if the practical man had in his hands at 
the same time an analysis by a trustworthy chemist, and results
