Blackberry Jam
From MRS. MARY S. MCNEAL, of Oklahoma, Alternate Lady Manager.
Put the fruit into a preserving kettle and boil fifteen or twenty minutes, stirring often and skimming off any scum that may rise; then add sugar in the proportion of three-fourths pound of sugar to one pound of fruit. Boil thirty minutes longer, stirring continually; when done, pour into small jars or jelly glasses.
