Jan., 1907. Annual Report of the Director. 



33 



It may be worthy of mention that the distinctness of the 

 printing on black labels has been much intensified. This impro ve- 

 ment has been brought about by the use of a size first and then the 

 application of an aluminum bronze powder. The former method was 

 to use aluminum ink only, which necessitated the taking of three 

 or four impressions of each label in order to obtain a final clear effect. 

 While more time is required to print the labels by means of the 

 bronze powder, the results seem to justify the additional labor.
