Land of the Post Rock: Its Origins, History, and People

In north-central Kansas, where woodlands are sparse and prairies expansive, rows of creamy-buff, brown-striped stone fence posts grace the landscape. These stately posts are shaped from the native rock known as Fencepost limestone, or simply post rock. Now tourist attractions, the posts are also regional trademarks that bespeak the resourcefulness of early Kansas settlers. Land of the Post Rock is a story of north-central Kansas and its people, and their relationship to the post rock. The authors weave together regional geology, geography, and economics with local history and pioneer folklore to describe how post rock shaped the area's development. They have recorded the story of a unique aspect of Mid-American heritage. Post rock played a vital role as the central Kansas upland evolved from a treeless grassland to an area of cultivated farms. Obliged to find a substitute for post timber, early settlers began turning back the sod and splitting posts from the rock layer that for hundreds of centuries had lain dormant. The rock became a central factor in the development of that segment of the plains as dugouts and sod houses gave way to substantial dwellings constructed of stone. This book contains a generous amount of local oral history. The authors traveled the region collecting stories about the early settlers' dependence on post rock to survive on prairie homesteads. Here, too, is ethnic history. Details are provided on the backgrounds, talent, and personalities of the European immigrants who settled the area and used the rock. Those who are curious about the physical nature of post rock and how it was formed will find answers in this book. The authors explain how the rock was quarried, how stone posts were set, and how post rock was prepared for buildings and other structures. The volume is illustrated with numerous black-and-white photographs, maps, and charts, as well as ten full-color photographs of post-rock scenes and structures. It can serve as a guide for interested explorers, because it includes specific information on where post-rock artifacts and buildings my be observed today. It is a major contribution to the preservation of the post-rock landscape and heritage.

XIV.— Geophysical Survey of a Magnetite Deposit in the Island of Tiree

I. Introduction Tiree is included in Sheet 42 of the Geological Survey One-inch Map of Scotland, issued in 1926. The corresponding Sheet Explanation has not yet been published, but a brief account of the geology of the island appeared in ‘Summary of Progress for 1922’ ( Mem. Geol. Surv., 1923, pp. 91-93). It was during the course of the mapping of the western part of the island by Drs. J. B. Simpson and A. G. MacGregor that the former discovered magnetite-rich rocks. In the memoir already referred to (pp. 105-106) Dr. Simpson described the occurrence as situated “at the north-west corner of Loch a’ Phuill, immediately east of a stone fence, which runs N.N.E., parallel to, and about 80 yards away from, the shore of the loch,” and gave the following details. “The magnetite is in the form of a band striking N.N.E. in conformity with the bordering gneiss, and is visible for about 150 yards before it disappears under surface deposits. The band is about 13 feet in breadth, and the middle seven feet appear to be fairly pure, but towards the edges the magnetite is interfoliated with quartz and garnet to a notable extent.” In the early years of the War attention was directed to this occurrence as a possible source of home ore and in 1941 a preliminary survey was made by Dr. Simpson, using a survey magnetic compass. The results of this investigation have not yet been published, but clearly show that outline indications of this nature This 250-word extract was created in the absence of an abstract
