train oil

Under the lamp there is always another vessel intended to receive the train-oil which may possibly be spilled.

Not for worlds would I undeceive the good fellow, not if this were train-oil.

It was train-oil, linseed and hempseed, crushed up all together, and the bugs were to eat it till they burst.

In a word, their houses are as filthy as hog-sties; every thing in and about them stinking of fish, train-oil, and smoke.
