The work done on import samples by each laboratory in each dis- 

 trict is shown by the following table : 



Examination of import samples. 



The number of importations allowed entry after relabeling was 

 unusually large, on account of the fact that a very large number of 

 shipments were detained for failure to comply with the net-weight 

 amendment to the Federal food and drugs act, which took effect 

 during the year. Partly because of this amendment, partly because 

 more attention was paid to the supervision of importations at ports 

 on the Pacific coast, and partl}^ because of abnormal trade conditions, 

 the number of shipments examined was nearly 2,500 in excess of the 

 number examined during the fiscal year ended June 30, 191J:. 



An effective campaign of inspection was conducted along a part 

 of the Canadian frontier to prevent the importation into the United 

 States of adulterated milk and cream. 



MISCELLANEOUS EXAMINATIONS. 



In addition to import samples and interstate samples, the field 

 laboratories of the bureau analj^zed a large number of miscellaneous 

 samples. The following table shows the number of miscellaneous 

 samples analyzed by each laboratory in each district, together with 

 the total number of samples of all classes analyzed in each laboratory 

 of each district .
