Page v - THE SURVEY IN ITS RELATIONS TO THE PUBLIC. The usefulness of the Survey is not limited to the preparation of formal reports on important topics. There is a constant and insistent desire on the part of the people to use it as a technical bureau for free advice in all matters affecting the geology or mineral industries of the State. A very considerable correspondence coines in, increasing rather than decreasing in amount, and asking specific and particular questions on points in local geology.
Page v - The cases commonly covered by correspondence may be classified as follows : 1st. Requests for information covered by previous publications. — This is furnished where the time required for copying the answer is not too large. "Where the portion desired cannot be copied; the enquirer is told in what volume and page it occurs and advised how to proceed to get access to a copy of the report.
Page 12 - Gieson," describes what he believes to be the earliest known terra-cotta roofing tile. These were found in the ruins of the Temple of Hera at Olympia, dating nearly a thousand years before Christ. This ancient tile consisted of two elements, a wide under piece (tegula) slightly curved, and a narrow, semicylindrical piece (imbrex) which was placed in an inverted position so as to cover the upturned edges of two adjacent tegulae. While the tiles from the Temple of Hera are probably as old as any authenticated...
Page 133 - ... 1225° for three hours. When removed they were completely amorphous (melted), but retained their position with hardly a trace of sagging. After this a number of similar slivers were prepared, mounted in the same way, and heated to temperatures of from 12oo° to 13oo° for a few moments. At their highest temperature a platinum rod was inserted through a hole in the top of the furnace and allowed to rest as a load upon the middle of the crystal bridges. Under this load the partially melted slivers...
Page 30 - ... roofs of this material. There undoubtedly will be a field for this material on large roofs of cheap construction, where extreme lightness is necessary, but for strictly first class and artistic work where something other than a flat or corrugated shingle is wanted, clay roofing tile will not likely be displaced. Scanty Distribution of Roofing Tile Plants.— This question is perhaps the most important in connection with the promotion of the business. With at present only about one plant to three...
Page 169 - The clay is four to seven feet in thickness, has practically no overburden and is underlain by a white water-bearing sand. It is yellowish, red, and bluish in color; a mixture has a yellow color, is very fine-grained, stiff and plastic. It is free from pebbles, coarse sand or coarse rock fragments. The clay is noticeably bluer...
Page v - Requests from private individuals for analyses of minerals and ores, and tests to establish their commercial value. — Such requests are frequent. They cannot be granted, however, except in rare instances. Such work should be sent to a commercial chemical laboratory. The position has been taken that the Geological Survey is in no sense a chemical laboratory and testing station, to which the people may turn for free analytical work. Whatever work of this sort is done, is done on the initiative of...
Page 60 - There are enough unpatented designs of tiles of perfectly commercial grade, in all styles, so that no one should think that a new patent design will protect him from competition. Today, it is a question of producing tiles of the proper quality at the proper price. As a matter of general interest to roofing tile makers, present and prospective, it has been thought worth while to record in this volume some statistics as to just what has been done in the way of patents on roofing tiles in this country....
Page 80 - Figure 2) of a glass jar with a capacity of about four litres, having a broad mouth and closed with a ground glass stopper. Through the center of the stopper is a circular opening into which fits the ground end of a short glass tube. The latter expands into a bulb a few inches above the stopper and is again contracted to small diameter beyond the bulb. The interior of the jar is thus...
Page 113 - Analysts of the Porosity Data. — In order to facilitate the reading and meaning of the data in the preceding table, an effort has been made to classify the clays shown into three different groups and to depict by curves the percentage porosity of the clays of each group. Group I. This group is of exceedingly narrow vitrification range. It comprises clays E, N, M and H. In none of this group do any serious or significant porosity changes occur prior to cone 02, but immediately following that point...
