New York AGRICULTURAL EXPERIMENT STATION. 39 
THE INVESTIGATION OF THE SEVERAL BREEDg 
OF DAIRY CATTLE, WITH KEFERENCE TO THEIR 
RELATIVE VALUE IN THE PRODUCTION OF 
MILK, BUTTEK AND CHEESE. 
In reference to this important investigation, I can but repeat 
the words of a former report: 
The investigation of this problem planned at this station has 
from the first been upon lines clearly laid down, confident that 
in no other way can a satisfactory conclusion be secured, and 
it is along these lines that it is intended to continue until an 
accumulation of testimony shall have been secured sufficient to 
reconcile many at present apparently contlicting opinions to con. 
firm many others which appear to be conclusive, as also to deter: 
mine many questions intimately associated with the leading 
problems, concerning which at present no rule of practice exisi:+ 
founded upon well ascertained experimental data. 
Of such immense practical importance is this investigation and 
of such scientific interest that it has been entered upon and carried 
forward with as little delay as possible, and so manifold and 
intricate are the questions involved in its discussion that a speed) 
-_ 
conclusion of the whole matter can only be hoped for as the resul. 
of prolonged investigation. 
In the following pages is presented additional data secured 
since the publication of the last report, a general discussion of 
which will be reserved until it has been presented. 
The following table gives the names of the several animals unde? 
investigation, their breed, date of birth, and dates of calving.
