termed trash, employed for packing opium for the China market. 
The opium, as received from the cultivators at the sub-fac q 
tories, varies in consistence, and is divided into six classes, whi eo 
the final classification of the drug is determined at the hea 
factory, where the opium is finally classified in 12 classes. T 
classification of the drug depends upon the percentage of solid — 
opium present when a sample is dried at 200° F. Th 
opium containing 20 per cent. of moisture would be terme 
~ opium of 80 degrees consistence. In the classification of opiul 
each class of opium has a range of three degrees. . The opiu 
received into the factory may vary in consistence from 8. 
degrees and upwards to 50 degrees or less, all opium cont 
ing only 50 percent. and under ofsolid opium being included?

is designated “above Bdala-bashi dar awal.’’? The assay |
