The samples taken represented 152 manufacturers and jobbers. 

 There were 237 brands, taken at 124 places, and from 200 different 

 dealers. 



The samples were placed by the sampling agent in glass bottles 

 provided with metallic screw caps, and containing a cork pad which 

 fitted close to the top of the bottle, and were then sealed up in a 

 carton and transmitted by express to the chemist. The analyses 

 and examinations were made by Dr. Wm. Frear, Vice Director and 

 Chemist of the State Experiment Station, and involved a large 

 amount of painstaking labor. The determination of the character 

 of the several grains, and adulterants used in feeds, is, of necessity, 

 made by the use of the microscope, and requires accurate knowledge 

 and familiarity with the forms of the several kinds of starch gran- 

 ules and fibre cells, of w^hich these several substa-nces are composed. 



The time required for the careful examination of over two hun- 

 dred samples, is very considerable. The approximate determination 

 oi the amount of the adulterants present, requires careful observa- 

 tion, and likewise consumes a large amount of the investigator's 

 time. The work, therefore, is such as will necessarily, cause delay 

 in securing results for publication, even after the samples are taken 

 and placed in the chemist's hands.
