comments, manufacturers have attempted to further destroy the 

 viability of the weed seed by grinding the screenings, and most of 

 the feeds now offered contain fewer whole seeds than formerly. 



We have attempted to determine approximately the total number 

 of seeds, as well as the number germinating in a definite amount of 

 molasses feeds collected in the Massachusetts markets during the 

 winter of 1909, and the results follow in tabular form : 



TABULATED DATA.* 



This work was done by G. H. Chapman, assistant botanist at the station. 



RESULTS OF THE WORK. 



1. The different feeds varied to a considerable extent in whole 

 weed seed content, as did also different samples of the same brand. 

 This condition depended not only upon the character of the material 

 used, but also upon the thoroughness of grinding. 



2. It is worthy of remark that of the twenty samples found to 

 contain weed seed, seven showed none that germinated, and in no 

 case did over one-half of the seed sprout. 



3. The seeds identified were crabgrass, foxtail, bindweed, ladies' 

 thumb, lambs' quarters, charlock, wild turnip, plantain, common 

 sorrel, dock and tumbleweed.
