Revised edition. "Muscadine grapes, which are native to the southeastern part of the United States, thrive in most soils of that region. They can be grown successfully in the Southeastern States, where American bunch grapes do not thrive. furthermore, they are suitable for home gardens as well as for commercial use. In fact they are perhaps the most satisfactory of all fruits for the home garden in this region. They cannot be grown, hoever, where temperatures as low as 0 °F occur habitually and may be injured at somewhat higher temperatures. Muscadine grapes are relatively uninjured by diseases and insects and produce well with a minimum of care, but they resopnd favorably to the good cultural practices recommended in this bulletin. The varieties described or listed produce fruit suitable for making unfermented juice, wine, jelly, and other culinary products and for eating fresh over a long season." -- p. ii
