Description of the Tables. 



The table on pages 132 and 133 contain a list of the 81 kinds 

 of weed seeds obtained from seeds which were examined in the 

 year 191D. 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.

 examinations of samples of seeds examined by the Station in 

 19TO. 



The table on pages 134 to 137 contain the analyses of 

 samples of seeds collected by the inspector in 1910. The inspec- 

 tor only drew samples from lots of which he was doubtful as to 

 their corresponding to their guaranty.
