While the results, as shown, are not as conclusive as might be desired, certain 

 facts are indicated. It may be mentioned that these experiments are but forerunners 

 of a series of tests with the feeding of molasses, and that, until further data have 

 been collected, these results cannot be regarded as conclusive. However, it would 

 appear that while molasses may be substituted as part of a meal ration and slightly 

 reduce its cost, its addition in any considerable quantity is not economical. While 

 molasses is of no inconsiderable value as a food, its chief desirability is in its appetiz- 

 ing and tonic qualities, the benefits of which may be derived by its being incorporated 

 with the meal in much lesser quantities than those tried. An addition of, say, 10 

 per cent of the meal fed allows of this, yet does not materially reduce the feeding 

 value of the concentrates. 



In order to ascertain whether or not increasing the molasses constituent might 

 prove economical, the test was continued as Experiment 2k,
