YIELD OF TURPENTINE AND ROSIN. 5 
The scrape was distilled the day following collection, but even in 
this case a comparison of the grades of rosin may be erroneous. At 
the time of distillation the price of turpentine was high, while the 
higher grades of rosin differed little in value, so that the quality of 
the rosin sometimes was sacrificed for a higher yield of turpentine.
