“The Drying Room, Opium Factory at Patna India”
“In the Drying Room the balls are placed to dry before being stacked. Each ball is placed in a small earthenware cup. Men examine the balls, and puncture with a sharp style those in which gas, arising from fermentation, may be forming.”
- The Truth about Opium Smoking, 1882
