Wash cucumbers well. Place in a large nonreactive container. Combine 1/2 gallon water with 1 cup salt, and stir until salt is dissolved. Pour over cucumbers. Place a plate on cucumbers to keep them submerged in liquid. Cover, and refrigerate overnight.Advertisement
Drain and rinse cucumbers, discarding brine. Pack into four to five wide-mouthed quart jars. Distribute pickling spices, garlic, and dill evenly among the jars.
Combine 6 1/4 cups water, the remaining 1/2 cup salt, the vinegar, and sugar in a medium saucepan. Bring to a boil, and pour into packed jars. Cool on a rack to room temperature. Cover, and refrigerate for up to 2 weeks.
