dc.descriptionPreface: The resistance of concrete to natural weathering has been studied since 1936 at an experimental exposure station located at Treat Island, Cobscook Bay, Maine, and since 1940 at a similar station at Salt Run, St. Augustine, Florida. The programs of investigation at these stations and at others located in New York State have previously been reported in Waterways Experiment Station Technical Memorandum No. 6-226, "Durability of Concrete Exposed to Natural Weathering," dated August 1947. Included in this supplement to Technical Memorandum No. 6-226 are data developed from those investigations which have been continued since 1947 and descriptions of several programs which have been initiated since that date. Further supplements will be issued from time to time as warranted by the data developed in these programs, pending a more complete report on those phases of the investigations not previously described. Authority for the work reported herein is contained in multiple letter of the Office, Chief of Engineers, dated 14 September 1948, subject, "Civil Works Investigations of Office, Chief of Engineers," item CW 604-Concrete "Continuation of Permanent Exposure Stations." The studies were conducted under the supervision of Herbert K. Cook and Bryant Mather by E. J. Callan, L. K. Farrior and M. H. Peabody. This report was prepared by E. J. Call-
