Erratum.
The article "Back to the energy crisis" by Mark Crawford (News & Comment, 6 Feb., p. 626) overstated American imports of petroleum and petroleum products for the years 1977 and 1985. Imports in 1977 averaged 8.8 million barrels per day as opposed to 8807 million barrels as stated. By 1985 imports had fallen to 5.07 (rounded) million barrels per day, not 5067 million barrels daily. The United States' use of petroleum-not foreign consumption as stated in the article-is projected to hit 17.7 million barrels per day in 1995. U.S. imports could then reach 9.8 million barrels a day.
