412 TWENTY-THIRD ANNUAL YEAR BOOK— PART VI 



the coming year we can arrange to be of a great deal more assist- 

 ance than we have in the past, providing we begin early in the year 

 to plan our work and outline a plan whereby we can co-operate with 

 the creameries and everyone interested in this work, with the idea in 

 mind of getting as many plants as possible interested. 



Grading of cream has many advantages and few disadvantages. 

 Such work should be thoroughly studied first. More failures are

 companies interested are satisfied and are at this time outlining an 

 extensive program for the coming year.
