This may be a new thing you learn today:
Approximately 600 short tons of tung oil is reported to be included among the commodities now enroute from Hankow to Shanghai.
From Wikipedia:
Tung oil is made from the pressed seed from the nut of the tung tree. Tung oil is considered a drying oil much as linseed, safflower, poppy and soybean oil. When applied, it provides a tough, highly water-resistant finish which does not darken noticeably with age as does linseed oil. This is not to say that it is a colorless finish; it still has a slight golden tint. Tung oil is also sometimes called China wood oil. It has been used for hundreds if not thousands of years in China to seal decorative and marine wood as well as porous masonry.
There certainly is a lot going on around the world during this time. Imagine, news in the newspapers. Too bad now they aren’t worth reading.
