The prices of a few samples are omitted, since these teas were not 

 purchased by the Department. As nearly as possible all the grades of 

 teas on the market are represented in this work. 



Many of these samples are of very inferior quality, but neither the 

 analytical nor microscopical data give positive evidence of the addition 

 of spent or foreign leaves. That this latter form of adulteration is still 

 practiced is evidenced by the work of a Canadian official chemist who 

 found two samples containing foreign leaves. 1 Dr. Jesse P. Battershall 2 

 examined nearly 2,000 suspected samples of teas under the United 

 States tea adulteration act, and states that he found foreign leaves 

 present in only a few instances. 



Some of the higher-priced teas contained frayed and unrolled leaves, 

 but not in sufficient quantities to justify considering the sample to have 

 been adulterated with spent leaves, especially as the relative propor- 

 tions of the soluble constituents of the teas varied little from the aver- 

 age for genuine, unadulterated samples. 



A large number of the samples examined by the writer were faced. 

 With the present ideas in regard to this practice, it can not be consid- 

 ered a form of adulteration, but facing should be condemned on account 

 of its use in making inferior teas appear to be of a superior quality. This
