Description of the Tables. 



The table on pages 174 and 175 contain a list of the 79 kinds 

 of weed seeds obtained from seeds which were examined in the 

 year 1909. They are arranged alphabetically in accordance 

 with the English name. As the common name differs in differ- 

 ent parts of the country, the scientific name following the 

 classification given in the last edition of Gray's Manual of 

 Botany is given for the purpose of identification. 



The table on pages 176 to 177 summarizes the results of the 

 examinations of samples of seeds examined by the Station in 

 1909. 



The table on pages 179 and 180 contain the analyses of sam-

 their corresponding to their guaranty.
