J. Money refunded if not satisfactory in 5 days Department of Agriculture Quizzes Farmers on Reports WASHINGTON. — That farmers throughout the country are receiving the Radio market news reports broadcast by the Department of Agriculture is shown by the replies to an inquiry sent out by Radio recently. About half of the replies received were from farmers, the rest being from grain dealers, banks, telephone .companies, and other agencies which serve the farmer. Radio has developed more rapidly in the Middle West than in other farm sections of the country, and this probably accounts for the fact that the inquiry shows the greatest interest to be in grain reports. Next in interest are livestock reports and weather reports.
