Superior fertilizer will be made from city sewage and garbage using a highly proven 10 day composting formula from Dr. Herbert Webber, Telford, PA, a famous biologist. Some users claim his product is twice as good as any other fertilizer. Ex ceptionally bug and disease resistant crops. Costs much less because raw material is free. Cities want to get rid of their sewage and garbage. Farmers need the fertilizer. Probably the most depression proof business. Get in on the ground floor. Work with an honest, reputable corporation, physically or financially. If you successfully solicit the cooperation of a city anywhere, you get well rewarded. Great potential.

Prompt identification of foreign insects can make the difference between success and failure in controlling harmful pests, Dr. Kim said. “Accurate identification of natural enemies, parasites, and predators is just as essential to pest For more information contact Edward P. Beaver Rockville, MD steam engineer or Lancaster Farming, Saturday, March 22,1980—C17 management as correct identification of the pest species,” Dr. Kim declared. When a destructive beetle was found on barley and oats in Michigan, identification of the pest as the cereal leaf beetle directed a search for its parasites into Europe, starting in 1963. Mass rearing and release of specific parasites began in 1967. Four of the five parasites introduced into Michigan and Indiana were successfully controlling the cereal leaf beetle by 1972. Elsewhere, accurate identification was a key factor in controlling the cottony-cushion scale in California. In the eastern United States, with the help of taxonomists, parasites of Japanese beetles were brought in successfully from the Far East. On the other hand, in complete knowledge of pest species can “bungle” control efforts. Early attempts to establish parasites to control California red scales failed when no one could distmguish yellow scales and related species from red scales. Finally, after taxonomists correctly identified California red scales, ef- Organic Center New Holland, PA PH 717-354-7064 or Tom Ward Florida Biodynamics Inc. St Augustine, FL or fective parasites were found in the Far East and were introduced. An error in classifying these same California red scales also sent entomologists (insect scientists) on another “wild goose chase,” searching for parasites in South America. Many parasitic wasps and flies are very much alike and thus are difficult to identify accurately, even by skilled specialists, it was noted. Mass rearing of parasites, especially tiny parasitic wasps, can be contaminated easily by unwanted but related species. Presence of improper species may go unnoticed for some time. And there are many insect species which look superficially alike among natural enemies. That’s where accurate iden tification of a species, based on good description and classification, can be the key to success in biological control, he said. Kniffen speaks to youths CLEMENTON - Donald M. Kmffen, animal science specialist at Rutgers University, spoke to members and leaders at a 4- H Livestock Seminar held recently at the Camden County Extension Building. Attending the program were 4-H members and leaders from Gloucester, Cape May and Burlington counties. In attendance from Camden County were the Goats Galore, Tansboro Trailblazers and Yearlings 4-H clubs. Kmffen covered several topics in the seminar: longevity, maximum ef ficiency and judging techniques. Each of these are crucial for the 4-H’er to have a profitable livestock project.
