" manures which have been found most applicable ; 
" suggesting, if possible, others which, from their 
" chemical properties, seem likely to supply deficiencies 
" in the soil. 6. The insects and diseases which are 
" found most destructive to the crops, with the remedies 
" where known." They conclude the report by saying 
that they are naturally desirous of commencing an 
undertaking which they feel confident will eventually 
strengthen the foundations of agriculture, and therefore 
pave the way for an extension of its superstructure, and, 
lastly, " That agriculture will never receive its full

" closely examined, and clearly defined.'' 
This subject, then, being one of vast importance to 
the agriculturist, I do think it the duty of this society 
to afford to the Agricultural Society every assistance 
in their power towards carrying into effect their great 
and beneficial undertaking ; and for this purpose these 
papers are written. 
I hope, therefore, now to be able, 
1. To describe the geographical limits not only of the 
Formation, but of each of the beds subordinate to it ; to 
project these upon a map of the scale of 6 inches to the 
mile, and to produce vertical sections of the hills, depths 
of beds, &c. 
2. To examine the chemical composition of soils upon 
the same strata, and to compare the infertile with the 
more productive. 
3. To notice the state of agriculture as at present 
existing over the country described, and offer suggestions 
for its improvement where required. 
The country which I now purpose to describe com- 
mences three miles South of Doncaster, and extends
