REPORT OF THE SECRETARY. 85 



domestic and 1,302 import samples at the Washington office gives a 

 general total of 22,974 samples examined in the course of the in- 

 spection work alone, including check examinations and other neces- 

 sary duplications in the work. 



DRUG INVESTIGATIONS. 



The important cooperation with the Post Office Department in 

 issuing fraud orders against medicinal agents sent through the mails 

 and proved to be of a fraudulent or injurious nature has been con- 

 tinued. As in former years, the consumption, cancer, and epilepsy 

 "cures" continue to form the most important classes of materials 

 handled. 



DAIRY PRODUCTS. 



While the whole range of dairy products is covered by the examina- 

 tions made, the evaporated and condensed milks and cheese formed 

 the bulk of the samples examined at the Washington laboratory. An 

 investigation begun in 1909 in regard to the concentration of evap- 

 orated milk was completed, and Food Inspection Decision 131 has been 

 issued on this subject. Condensed milk, both sweetened and unsweet- 

 ened, continues to be made in many instances from skimmed milk; 

 the violations in the cheese trade consist most frequently in short 

 weight or the sale of a skimmed cheese for a full cream. A total 

 of 347 cases were prepared during the year on such products, nearly 

 200 of which are milks and creams, 44 cheeses, and 40 ice creams. 



WATERS. 



Mineral and table waters are examined both at source and as found 

 on the market. As a result of the analysis of 161 domestic samples, 

 39 were found to be adulterated or misbranded and 6 seizures were 

 made, while of the 39 imported waters, the exclusion of 11 was recom- 

 mended. In this connection an extensive survey of the mineral 

 waters of the United States has been undertaken and the data in re- 

 gard to the waters of the New England States have been issued as 

 Bureau of Chemistry Bulletin 139. This material is of the utmost 

 value to physicians and consumers, especially those depending on the 

 waters for any therapeutic effect, as well as to those called upon to 

 pass on these waters in the enforcement of the law. Correlated 

 studies include the analysis of public water supplies, investigations 

 for the improvement of methods of water analysis, the character of 

 chemicals used in water purification, etc. 



CATIXE FOODS. 



The studies o"f cattle foods and grains are by no means confined to 

 the aspect of adulteration, since economic problems, such as the feed-
