Kiln schedules are completely assembled Research Institute, Ibaraki, Japan, for supplying and written out for easy use. Schedules for several schedules for Japanese as well as several tropical thicknesses and specialty products (e.g. squares, woods. Significant assistance in computer handle stock, gunstock blanks) are given for many programming and table formatting was provided by species. The majority of the schedules are from the David B. McKeever, Research Forester, and world literature, with emphasis on U.S., Canadian, and W. W. Wlodarczyk, Computer Programmer Analyst, British publications. Revised schedules have been both of the Forest Products Laboratory, Forest Service, suggested for western U.S. and Canadian softwoods U.S. Department of Agriculture, Madison, WI. and for the U.S. southern pines. Current thinking on high-temperature drying (temperatures exceeding 212 °F) schedules for both softwoods and hardwoods is reflected in suggested high-temperature schedules for selected species.
