AGRICULTURAL STATISTICS. 
A desire faithfully to discharge the duties de¬ 
volved on this office in relation to agriculture, 
prompts me to seek impartially from persons of 
known experience and research, the best informa¬ 
tion on the several topics embraced in this circular, 
and upon such others as may, in the judgment of 
practical men, contribute 'to the benefit of that 
vitally-important branch of our national industry. 
Comprehending, as this circular necessarily does, 
a variety of subjects, with all of which no one 
person can be supposed to be practically familiar, 
it is presumed that each one to whom it may be 
addressed will confine his observations to such 
matters as have come under his own experience. 
Such information it is the purpose of Congress in 
this mode to collect and distribute for the common 
benefit of the agricultural community, and it can¬ 
not but be, in the aggregate, of enduring value. 
Excluding mere estimates and local details of 
weather and crops, which may be found in the able 
agricultural journals of the country, the design of 
the> annual report, to which you are invited to con¬ 
tribute, is to bring to light and register in a perma¬ 
nent form, important facts and discoveries, the 
results of actual experiment, which might not 
otherwise become so soon nor so widely known. 
It is likewise intended to constitute a repository 
of agricultural statistics, founded upon official and 
other reliable data, which may serve as authentic 
bases for the use of the politico-economical inquirer 
and legislator. 
Whatever may have been tested and found new 
and useful in practice, together with important 
agricultural statistics, will be acceptable: especially 
suggestions as to the introduction of such new 
objects in the way of machinery, animals, pro¬ 
cesses, or plants, as may tend to the profitable 
diversifying of the application of labor and capital 
to the all-important science of cultivation. 
With this brief explanation of the objects con¬ 
templated by Congress, and leaving to your dis¬ 
crimination to judge how you may best and most 
conveniently assist in their accomplishment, I beg 
leave to tender in advance, for any contributions 
you may be pleased to make, my respectful acknow¬ 
ledgments. Thomas Ewbank, 
United-States Patent Office, ) Commissioner. 
Washington, July, 1849. )

value as food for stock compared with Indian corn

duction—weight per bushel—average per acre, and
