The Mercer Extension office will be hosting an open house this week in observance of their 100th anniversary. The public is invited Tuesday, May 6th from 3-to-5 p.m. to 2106 SE 3rd Street in Aledo. On May 8, 1914, President Woodrow Wilson signed the Smith-Lever Act which created the Extension Service – the educational arm of the U.S. Department of Agriculture. The Land Grant University System was designed to make the benefits of education available to farmers, craftsmen, home makers- the working people. From that beginning came Extension, the network that delivers research and information from the University of Illinois to the community. Today, Extension serves both urban and rural areas by offering programs in four broad areas: 4-H Youth Development, Agriculture & Natural Resources, Community & Economic Development and Nutrition & Wellness.
