Nowadays they are known as the Fox Grapes (_Vitis vulpina_), the Frost Grape (_V.

cordifolia_), the _V.

aestivalis_, the _V.
labruska_, &c.

The fruit of the Fox Grape is dark purple, with a very dusky skin and a musky flavour.

The Frost Grape has a very small berry, which is black or leaden-blue when covered with bloom.
