 or C. L. King (chairman), F. A. IVarson, G. Pinchot, Mrs. A. YV. Smith, J. W.

 maintained. A summary is given of data submitted by seven investigators as to 

 the cost of milk production in 490 herds, averaging just under 20 cows each, 

 located in Minnesota. Michigan. Massachusetts, Connecticut, New York, and 

 New Jersey. The yearly average quantities of feed and labor required to pro-

 summer and winter averages are provided by one of the reports, that from
