Available in PDF, EPUB and Kindle. Book excerpt: John Allen Howe's book, The Geology of Building Stones, written in 1910, was the first major reference work to feature information on the considerable range of building stones which were being used in the UK and which were still being quarried at that time. This important and useful publication, now reprinted by Donhead, offers very detailed information on the appearance and qualities of the various types of stone being used at that time, including granite, sandstones, limestones and other lesser known building stones, specific to certain geographical areas. It also includes a good introduction to the effects of stone decay, in particular the problems of pollution, frost and organic growth in the breakdown of stone. His chapter on testing of stone was very much ahead of its time, since nearly a century later Britain is only now starting to obtain its first standard tests for building stone, in the form of European Standards. This book will be a valuable source of reference for conservators, architects, surveyors, engineers and anyone seeking to identify stone in old or historic buildings.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from British and Foreign Building Stones Specimens of Building Stones brought together to form a collection are usually arranged according to their lithological character irrespective of their age. Possibly this method may have been found to be the most convenient for architects and builders, other wise it would not have been so generally adopted. Bearing in mind however that the present collection is primarily for the use of students of geology at Cambridge University, it has been thought that the specimens will be more helpful to them, if they are arranged in stratigraphical order, hence this method has been adopted, except in the case of the igneous rocks.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Building Stones and Clays: Their Origin, Characters and Examination The present volume may in some sense be considered as an outgrowth of the author's previous work on cementing materials, for it deals with natural materials which are closely related, either as constituents or as competitors, to the manufactured products therein discussed. It may be noted that little space has been devoted to a de scription of the local distribution of building stones and clays. The inclusion of such data, relative to products which are nat urally so common and so widely distributed, tends to convert a general treatise into a mere directory of the quarry and clay product industries. The extensive reference lists which are pre sented, however, will serve to point out where information re garding the stone or clays of any particular state may be found. Attention should also be directed to the chapters relative to the examination and valuation of clay and stone properties. So far as known to the writer, most of the material therein pre sented has not been touched upon in earlier works on these subjects.

Book excerpt: Excerpt from The Geology of the Road-Building Stones of Massachusetts: With Some Consideration of Similar Materials From Other Parts of the United States Of each deposit which has been examined, samples were selected in tended to represent the average character of the material there found, and a lot of about 25 pounds was taken to be used in the experiments to determine the resistance of the stone. This was collected in bits of from 1 to 3 cubic inches in bulk, so as' to obtain a better average of quality. At the same time specimens were chosen for display in a cabinet and for the study of the petrographic character of the stone. Where the material consisted of glacial bowlders and pebbles, which in a large part of Massachusetts afford the only conveniently accessi ble road stone, an effort was made to obtain an average sample which would fairly illustrate the quality of the material that must be employed in road construction. Experience has Shown that while it would be pos sible by the exercise of moderate care in selecting the bits greatly to improve the quality of the erratics used in the crushers which supply the broken stone, it is difficult to induce the men who are employed in the work to take the needed pains.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Geology Will see that they receive various treatment before they become part of a building. The stones of the walls have been chipped and dressed with chisels and hammers the marble of the chimney-pieces has been smoothed and polished; the slates have been split into thin plates. But some of these building mate rials have undergone much greater changes. The bricks, for instance, were originally soft clay which has been hardened by being baked in ovens. The mortar by which the stones or bricks of the walls are held together. Has been obtained by burning limestone in kilns. The iron used in the house was first of all in the state of a dull red or brown stone, which had to be roasted and melted before the clear bright metal came out of it. I 3. But although these various stones differ so much from each other, they agree in one point - they come from underneath the surface of the ground. If you could trace back each of them to the place from which it came you would find that the freestone and limestone were taken out of quarries, perhaps not very far away, that the slates were cut out of the side of some hill, probably in Wales, that the marble was quarried out of some distant moun tain, possibly in Italy, that the coal was dug out of mines, sunk deep into the earth in some part of Bri tain, and that the bricks were made from clay dug out of pits on some low ground in your neighbourhood.

This acid is subsequently dissolved out of the atmosphere and brought into contact with the stone by means of rain.

Book excerpt: Excerpt from Stones: For Building and Decoration Since the appearance Of the first edition of this work there has been a very notable increase in the output of building stone from American quarries. How great this has been cannot be stated, unfortunately, since statistics are not available, but it is probable that the total annual output, as well as the amount Of capital invested, have both more than doubled. This is due not merely to the opening up Of new quarries, but also to an enlargement Of those already in existence and a very great increase in their equipments. Where but a few years ago hand labor or at best a few steam drills were chiefly relied upon, one now finds numerous and expensive machines in the form Of steam-drills and channellers, while at the yards are pneumatic tools, planers, . Lathes, polishers, saws, and grinding beds representing Often an outlay Of many thousands Of dollars. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
