VOLUNTEERS - Persons who receive a voluntary
conveyance.
It is a general rule of the courts of equity that they
will not assist a mere volunteer who has a defective
conveyance.
Persons who in time of war offer their services to
their country and march in its defence.
Their rights and duties are prescribed by the municipal
laws of the different states. But when in actual service
they are subject to the laws of the United States and
the articles of war.
