Freeman spoke to theta at the National 4-H Conference Center at Chevy Chase, Mary land. The secretary said that young people in rural areas are. helping to overcome the school dropout problems and to provide day care centers for working m'others He em phasized that projects such as these would be of great benefit to rural America if multiplied thousands of times ovei through 4-H club work. Freeman highlighted two particular areas in which ru lal youth are at a disadvan tage coirpaied with those in the urban centers—edudation and employment He said that the average educational attainment in ru ral areas is about two years less than in the cities. Ru ral teachers are paid less and rural schools are less well equipped The best, up-to-date vocational training schools for space age occupations are con centrated in the cities Fai moie urban than imal young people have college facilities within commuting distance And since a family living in rural America is twice as likely to be living in poverty, the economic oppoitnnity for advanced s'chooling is often less than in the cities, the Secietaiy said Job oppoitunities are also concentiated in the urban aieas He said that a lecent suivey showed that in the area serviced by the survey ing agency job opportunities and training program; are deficient • DHIA (Continued from Page 1) formance is more meaningful than dairy type scores or show ring characters.

The Vast majority of the farmland of our nation needs tremendous applications of lime to bring the soil up to top productive capacity The agronomists es timate that over 80 million tons should be used annual ly. as comipaied to the °6 million tons used in 1963 Hence, it is obvious that, whether the soil is limed to supply plant nutuents or to neutralize soil acidaty, it needs to be limed Whatever the puipose, the results are con seivation of our greatest nat ural resource the soil and greater production with increased returns to the farm- CERTIFIED GEORGIA TOMATO PLANTS Rutgers and other popular varieties FRESH PLANTS TRUCKED FROM GEORGIA Also Egg plants, Cabbage plants, Onion plants, Pepper plants, etc. To place orders, Call: Quarryville 786-2166 Lancaster 687-6603 HOWARD E, GROFF COAL, GASOLINE & FUEL OIL 111 East State Street QUARRYVILLE, PA.
