OLIVE OIL.
Reading edition
The oil generally used for this purpose is a refined grade of cottonseed oil (the stearine or fat being removed from the crude or fresh oil.) It can be bought of any good wholesale oil dealers. It is put up in bottles called pints, holding in reality only 10 ozs.; in half pints, holding 5 ozs. Put on a foreign sounding label (carried in stock by label houses). Pasting an inch and a half of tin foil around the cork and neck completes the job.
This oil is both as pure and strong as the genuine olive oil, and much cheaper. Olive oil pure is almost impossible to buy at any price.
