A most interesting experiment in frost control is being tried out by Marvin W. Hewitt, who operates the Q. & H. Cranberry Company, Inc., marsh at City Point, Wisconsin which is in the Town of Hiles. Mr. Hewitt has installed two powerful wind machines. The purpose of these so-called "Windmills," is to break up layers of inverted air, and thus prevent loss from any damaging frosts which may occur. These machines were first tried out in Florida citrus groves. The miaoMnes are mounted on 15 to 20 feet iconcrete bases and eaoh is expected to protect 10 acres of marsh from "; Mr. He- witt is depending on the experience of the orange growers, who have been "beating frosts," with wind machines since 1958. Mr. Hewitt is quoted in Mil- waukee Sentinal as saying, "I got interested in them, when I saw one in use in a peach grove in Georgia four years ago. The temperature fell to 23 degrees that night, but the machines which had been set up saved the crop. Neighbors lost ; On each of the two machines 15- fbot fans are powered by 340 horse- power gasoline engines. The columns store 600 gallons of fuel for the engines. The entire motor and fan unit rotate slowly, making a com- plete turn in 4% minutes. The motor can be operated by a thermostate or from controls at the base of the column. Leo Sorenson of Wisconsin Rapids, cranberry consultant has the fran- chise for the machines and worked with Mr. Hewitt on the installation. Emmit McPhaiil, field engineer for the Food Machinery land Chemical Conporation of Lakeland, Florida did the actual work of installing the machines. The big fans are mounted at a slight angle. Fans draws down warm air iand distributes it over the marsh. It is claimed marsh temperature can be raised eight degrees i
