From the Lawrence Daily Journal-World for June 10, 1971:

• Swarms of mosquitoes were circulating during the daylight hours in the Lawrence area, but “they really get organized for mass assaults after the sun goes down,” according to today’s Journal-World. It was said that the mosquito population could possibly drop off rapidly within a matter of days, but the threat of hordes of chiggers lurking in the grass was a certainty “until frost time in September of October.”
• The Cooperative Farm Chemicals fertilizer plant east of Lawrence was planning an expansion, allowing for 1,000 tons per day ammonia production. To that end, an ammonia converter was being shipped to Lawrence by rail from Titusville, Pa. Together with the three special rail cars required to carry it, the converter weighed one million pounds. The 65-foot-tall converter, 12 feet in diameter, and the accompanying heat exchanger (23 feet tall) looked “like space program devices,” according to a picture caption.
