74 MAINE AGRICUIvTURAIv EXPERIMENT STATION. I905. 



C. A medium grade goods which carries considerable cotton 

 and some hull, very good in color, but of poor flavor. Such 

 meal will usually carry about 35 per cent protein. 



D. A cottonseed meal of very good appearance, with the hulls 

 and cotton so finely ground as not to be readily detected. This 

 class is, however, lacking in the good flavor of high grade meals. 

 Such meal will usually carry about 25 per cent protein and 

 because of its good appearance is the most dangerous adulter- 

 ated meal in the market. 



COMPOSITION OF THE COTTONSEED MEAL USED IN THIS 

 EXPERIMENT. 



When this study was undertaken, the two grades of cotton- 

 seed meal referred to as A and B in the preceding paragraph, 

 were readily found. About this time a jobber received several 

 car loads of a meal of "grade C" and because of its poor appear- 

 ance sent samples to the Station for analysis. These goods 

 proved so poor that they were shipped out of the State, but the 

 jobber kindly furnished us with enough for the purpose of this 

 investigation. It was only after considerable correspondence 

 that we were able to obtain from a Massachusetts house enough 

 of the poorest grade ("D") cottonseed meal for the experiments 

 here reported. 



COMPOSITION OE THE COTTONSEED MEAES STUDIED. 



The description of the samples and the analyses of the four 

 grades of cottonseed meal follow. 



Cottonseed meal A was prime meal in color, taste and compo- 

 sition. 



Cottonseed meal B was of good texture and carried but little 

 lint or hulls. It was, however, dark in color. This together 

 with its higher water content indicates that it had undergone 

 some, probably slight, fermentation. 



Cottonseed meal C was a medium grade goods with consid- 

 erable lint and hulls. It was of good color, but poor flavor. 



Cottonseed meal D appeared at first glance to be fairly good. 

 It was of good color and apparently contained but little lint or 

 hulls. It was lacking in the nutty flavor of the high grade meals 

 and was, as the analysis shows, very low grade goods.
