For each of these Bulletins there has been a steadily 1 incrpadiie 
demand, and it is noteworthy that while many write to secure, so 
far as they may be able, all the Bulletins published, the number 
is far greater of those who prefer specific requests for certain 
Bulletins to which their attention has been directed through the 
agricultural press, thus showing that these Bulletins have happily 
met with specific wants for information among our farmers, who ~ 
as never before appear to realize that science can aid them in 
their work. 
An interesting and instructive illustration of ia avidity with 
which our farmers accept new facts pertaining to their calling, or 
old truths presented in a novel way, was seen in connection with 
the exhibit made by the Station at the State fair at Albany and 
elsewhere. Along with a collection of fruits and vegetables, 
there was prepared and sent several series of glass bottles showing 
the actual amount of the several constituents present in several of 
the leading food materials in common use, and along with this 
the following circular giving a full explanation of this exhibit:

The exhibit of foods, illustrating their chemical composition, is 
intended as an object lesson for those farmers who will study it.
