 thoroughgoing work of the chemists. 



It is the chemists who distinguish the edible from the non- 

 edible, the useful from the non-useful plants. The varieties 

 of "toadstools" which are healthful and nutritious have been 

 determined by the chemists and it is them we must thank for 

 the establishment of the mushroom industry in the United

 the sunflower that a delicious salad oil may be made from 

 its seeds, that the resulting "cake" is of the highest nutritive

 of soil in this country, the chemists already know it or they 

 are, with all possible diligence, seeking the information. The
