Field Experiments on Clover-Seeds 
the plan fixed upon in instituting a definite experimental inquiry . 
for it is impossible otherwise to obtain comparative results and 
clear indications of tlie peculiarities of action of the various 
manuring elements. 
In a former paper on field - experiments on clover -seeds, I 
gave a detailed account of the reasons which induced me to select 
the manuring matters which I employed in previous experiments, 
and which I likewise used, with slight variations, in all subse- 
quent field-trials upon clover-seeds. I need not, therefore, refer 
to the same subject on the present occasion. 
The failures which I experienced on heavy land with potash- 
manures in 1866, induced me to experiment during the last two 
seasons chiefly on light land, and the object of the present paper 
is to record the results of experiments on clover-seeds and perma- 
nent pasture, which, under my direction, were carried out with 
praiseworthy zeal by several of my agricultural friends, in whose 
skill and care in making field-experiments I have every reason to 
place full confidence. 
Field-experiments on Clover-seeds, made in 1867 at EscricU Park 
Home Farm, hij Messrs. Coleman and Hull. 
The field upon which the following experiments were tried 
grew barley in the preceding year. The usual mixture of clovers 
and Italian rye-grass was sown with the barley. The seeds came 
up well, and the plant was tolerably good and uniform on the 
piece selected for the experiments. Apparently the selected 
piece of land was uniform in depth and in its gerreral character. 
It was divided into eleven equal and adjoining plots of l-20th of 
an acre each. The eleven plots were treated as follows, as regards 
manure : —
