Excerpt from Results of Spirit Leveling in Wyoming, 1896 to 1912, Inclusive The connection with tidal stations for bench marks in certain areas that lie at some distance from the seacoast is still uncertain, and this fact is indicated by the addition of a letter or word to the right of the word datum on tablets or posts. For such areas corrections for published results will be made from time to time as the precise level lines of the United States Geological Survey or other Govern ment organizations are extended. Topographic maps - Maps of the following quadrangles, wholly or partly in Wyoming, have been published by the United States Geological Survey up to November 1, 1913. They may be obtained, except as noted, for 10 cents each or $3 for 50, on application to the Director of the Survey, at Washington, D. C.
