A striking aspect of today's cities is their rapid outward thrust. Urban land values being what they are, cities gobble up farmland at the rate of about 400,000 acres a year. At the same time, vacant lands within the city are bypassed because of their high price. Utilizing these sites would not only save the city the cost of extending services and utilities out into the fringes, but it would also take the pressure off the agricultural land. The author concludes with the admonition that urban land values must be lowered to encourage more building within the city.
