Cranberries are among the true natives of Cape Cod. The plant, _Vaccinium macrocarpon_, is a low evergreen shrub of the heath family that grows in bogs. Legend has it that the plant originally was named craneberry because its small, bell-shaped, pink flowers look like the neck and head of a crane, or heron, that stalks marshes and bogs. The deep red, nearly round, acidic berry is almost a half-inch in diameter. Indians called cranberries sassamanesh. They used this fruit as food and medicine; they mixed ripe berries with dried venison to make pemmican and placed roasted unripe berries on wounds. They also taught Pilgrims to use wild cranberries in their foods, and the colonists shipped 10 barrels of them to Charles II, but he found them too tart. Cranberries remained popular on the Cape, however, and by 1773 anyone caught picking more than a quart in Provincetown before September 20 would be fined a dollar—and would have to surrender the berries. Sailing ships served cranberries to their crews to prevent or cure scurvy. In 1813 Henry Hall of North Dennis made a discovery that led to commercial production: the berries became invigorated when sand drifted on the plants. Soon other Cape Codders were purposely sanding their bogs, and production was rising. By 1855 Cape Cod was a major Massachusetts producer with 2,408 acres in cranberries. Today about 1,250 acres are in production, 10 percent of the state’s total. Besides needing bogs with good peat bottoms, growers must have a water supply for sprinklers or enough water to flood their bogs through a series of ditches. Between November and March, and occasionally at other times, bogs are flooded to prevent frost from killing the vines. Ice up to 8 inches thick is allowed to form and the water below it is drained off. To sand the bogs, the ice is covered every 3 to 5 years with up to an inch of sand, which sinks to the bottom when the ice melts. In April the meltwater is drained off. Harvesting starts in September and continues through October. In this old postcard (below), pickers armed with wooden-toothed scoops move across a bog harvesting the berries. Today the process has been mechanized. More than 100 cranberry varieties have been developed, but the Early Black and Howes are direct descendants of the wild ones growing on the Cape. Processors now produce sauces, juices, and relishes that have become as closely associated with Thanksgiving as the Pilgrims and turkeys. ############################################# Marconi’s Wireless Station [Illustration: (Guglielmo Marconi with his wireless telegraphy equipment.
