 being run together. Wheat screenings are the weed 

 seeds, shrunken and broken kernels obtained in the pro- 

 cess of cleaning and grading wheat preparatory to milling. 

 In Table CXV is shown the average composition of 

 each of these by-products, together with that of corn 

 for the purpose of comparison.
