Nessmuk's Dope

In giving the recipe for his dope, Nessmuk says that it produces a glaze over the skin and that in preventing insect bites he has never known it to fail. This is the dope:

Pine tar3 oz.
Castor oil2 oz.
Oil of pennyroyal 1 oz.

Simmer all together over a slow fire, and bottle.

This is sufficient for four persons for two weeks.
