 opportune time to push this line of work because of the com-

The Exchange Bureau will be continued and an effort 

 made to make it more effective. 



These many lines, in addition to the general demand, al- 

 ways coming during the year will give the representative of 

 the Iowa State Dairy Association a full schedule for 1922.

 time.
