REPORT OF EXTENSION WORK IN DAIRY 

 MANUFACTURES. 



BY H, C. JORDAN. 



Exteiuletl efforts will be necessary among cheese makers of the State 

 to educate them to tlie need of making- better quality American or Ched- 

 dar cheese. Cheese made at the present time, es/pecially in the Lower 

 Peninsula of the Sta/te, is entirely too moist and spongy to be a safe 

 article of commerce and cannot be cured properly without developing bad 

 flavors and weak body. 



Forty-eight factories were visited (since March 1) and individual in- 

 structions given to forty-eight cheese makers to improve the quality of 

 cheese by eliminating excess moisture, the use of pure lactic cultures 

 recommended to overcome gas producers and other undesirable bacteria. 



Moisture tests of cheese have been made so far at twenty factories to 

 detennine the relation of moisture to the general quality of cheese. This 

 work will continue with a view to educating cheese makers to produce 

 firmer cheese, instruct them in the use of the moisture test, and, finally, 

 limit the moisture content of cheese hj law. 



AVork for the present must necessarily be confined to getting cheese 

 makers to realize the need for improvement in the quality of their product. 

 To some extent, this has been accomplished, but competition between 

 milk buyers is keen, and the temptation of increasing yield by incorporat- 

 ing an excessive amount of moisture will probably have to be stopped 

 by law, limiting moisture in cheese by legislation. 



Work will continue along these lines during the coming year, and 

 efforts will be made to obtain co-operation of cheese dealers to get proper 

 grading of the cheese and pay for them according to qualit\\ 



This work has been conducted with 28 factories. 



REPORT OF EXTENSION WORK IN ENTOMOLOGY. 



BY R. M. HAIX. 



The month of July was spent in tlie Upper Peninsula in demonstration 

 of the use of poison baits in the control of grasshoppers. These insects 

 were very bad at that time, many fanners even lost their hay crops. This 

 work was continued into the fore part of August, the time being spent 

 largely in the field. 



The grape district around Lawton and Paw Paw was then visited to 

 follow up the measures taken earlier in the season against the grape lea'f- 

 hopjrer and grape berry moth, noting the success of the treatments that 

 had been applied earlier in the season. 



The demonstration of a repellant against the flat headed apple tree 

 borer was taken up at that time and applications made.
