INTRODUCTION. 



This bulletin had its orij-iu in a plan of handling; starters designed 

 by this department for the short course students in dairying. Mr. 

 W. R. Wright, now of Stillwater, Okla., employed it in his class work 

 and Mr. L. D. Bushnell has carried on the work to the present time. 

 Both have contributed in various ways to its improvement and have 

 made every effort to render it of practical value to the butter- and 

 cheese-maker. Much credit is due to Mr. F. O. Foster in. confirming 

 its application to dairy practices. 



Having had the method set forth in this bulletin under considera- 

 tion and investigation for four years, and having found it safe, we 

 have no hesitancy in recommending it to every butter- and cheese- 

 maker who is able to appreciate what a good starter is and, further, 

 has it in him to appreciate what it means to manipulate a starter.
