326 IOWA DEPARTMEiNT OF AGRICULTURE 



Experience in the practical workings of the department has dem- 

 onstrated that the best service is rendered by a division of the work 

 into three classes. 



To carry out the provisions of the dairy law having for its i)ur- 

 pose the promotion and extension of dairying, as "well as the stand- 

 ardization of dairy products, we must employ for inspectors men 

 who are schooled in dairy science and qualified by experience in the 

 field. 



The manufacture of butter is based upon sound scientific princi- 

 pals and only those who are familiar with the art are competent to 

 be of assistance to the creamery in need of help. 



To be of service to us the inspectors enforcing the food and sani- 

 tary laws must be familiar with commercial .channels through which 

 food-stuffs are marketed, must be conversant on the subject of 

 proper methods of handling and storing foods, and must possess 

 sufficient training in sanitary science to secure a practical applica- 

 tion of the several laws. 



The testing of wagon and track scales is another work calling for 

 special training. To do this work properly and render the scale 

 owner the service he is entitled to for the fee paid, the inspector must 

 be familiar with the construction and installation of scales and 

 should have sufficient training in this line of work to be able to make 

 necessary adjustments. He must be competent to advise scale own- 

 ers as to what repairs are necessary for defective and w^orn instru- 

 ments. Modern weighing devices from the small computing counter 

 scales to the large automatic hopper scales and track scales which 

 weigh a car of grain as the car passes over are complicated meeh- 

 anism which cannot be "puttered" with by the novice. 



.From the above statements it may be seen how hopeless the task 

 would be tO' select eighteen men capable of doing the several lines of 

 work properly. 



The state is no more able to employ men who can do successful 

 work in diversified fields than are the large manufacturing concerns 

 who must employ different salesmen to represent them in their dif- 

 ferent lines. 



As a matter of fact it is difficult for this department to secure and 

 retain the services of men who are competent to do the work in the 

 various fields pursued by us. The experience gained by our men 

 qualifies them in a few years for positions at an advance in salary 

 and the state is compelled to compete with commercial concerns for 

 their services.
