The State of Iowa (Supplemental supplement, Code of Iowa, 1915, 
section 2515-f) in adopting a State brand or trade-mark (see fig.

mittee of five members, consist- 
ing of the president of the Iowa 
State Dairy Association, the 
president of the Iowa State 
Buttermakers' Association, the 
dean of the division of agricul- 
ture of the Iowa State College 
of Agriculture and Mechanic 
Arts, the professor of dairying 
of the same institution, and the 
dairy and food commissioner of 
the State of Iowa, who have 
control of the use of the trade- 
mark under such rules as may be considered necessary. The follow- 
ing rules and regulations governing the use of the Iowa butter trade- 
mark were issued in Bulletin No. 16 of the Iowa dairy and food
