    The Mining Districts of the Western United States

    Get PDF
    The mining districts of the Western or Cordilleran States are numerous and scattered over wide areas. The first attempt to locate all of them on a single map was carried out by the writer in 1907, with the aid of Mr. J. M. Hill and the statisticians in charge of the offices of the Survey at Denver, Salt Lake City, and San Francisco (Messrs. Chester Naramore, V. C. Heikes, and C. G. Yale). This map of the Western States was included in the annual volume of Mineral Resources of the United States. The large area covered and the necessity of adding explanatory tables made this map cumbersome to handle. When a revision was decided upon in 1910 and assigned to Mr. J. M. Hill, it was found advisable to map the several States separately and publish the maps, with more extensive explanatory text, in the convenient form of a bulletin

    The Critical Role of Islands for Waterbird Breeding and Foraging Habitat in Managed Ponds of the South Bay Salt Pond Restoration Project, South San Francisco Bay, California

    Get PDF
    The South Bay Salt Pond Restoration Project aims to restore 50–90 percent of former salt evaporation ponds into tidal marsh in South San Francisco Bay, California. However, large numbers of waterbirds use these ponds annually as nesting and foraging habitat. Islands within ponds are particularly important habitat for nesting, foraging, and roosting waterbirds. To maintain current waterbird populations, the South Bay Salt Pond Restoration Project plans to create new islands within former salt ponds in South San Francisco Bay. In a series of studies, we investigated pond and individual island attributes that are most beneficial to nesting, foraging, and roosting waterbirds

    Durfee & Peck. Letter from the Secretary of the Interior, inclosing an account of Messrs. Durfee & Peck, for rent of agency buildings at Fort Berthold. February 11, 1871

    This letter, dated February 11, 1871 from United States (US) Secretary of the Interior Columbus Delano to Speaker of the US House of Representatives James G. Blaine, also known as US House of Representatives Executive Document 115, transmits communications from US Commissioner of Indian Affairs Ely S. Parker, Dakota Territory Governor and ex-officio Superintendent of Indian Affairs John A. Burbank, and D. W. Marsh, agent for the Leavenworth, Kansas firm of Durfee & Peck, from whom the Upper Missouri Indian Agency has been renting the Fort Berthold Agency buildings for the sum of 3,500 per year. The agent for Durfee & Peck has offered to sell the buildings for 16,000, and the matter is being respectfully submitted to Congress for such action as may be deemed proper by that body. The document also contains a detailed inventory of buildings and structures to be included in the purchase.https://commons.und.edu/indigenous-gov-docs/1112/thumbnail.jp

    Earthquakes in California in 1890 and 1891

    The following paper is a continuation of records of the same kind by Prof. Keeler and myself and it brings the list up to the end of the year 1891. It records all the shocks observed or felt on Mount Hamilton, and all those reported to the Lick Observatory by letter, as well as newspaper reports of such earthquakes as occurred in the state during that year. No systematic examination of the newspapers has been made, however, and reports may have escaped notice

    Earthquakes in California in 1898

    The following paper is a continuation of similar records furnished by officers of the Lick Observatory, and completes the list up to the end of 1898. It records all the shocks observed or felt on Mount Hamilton, and all those reported to the Lick Observatory by letter, as well as newspaper reports of such earthquakes as occurred in the State during the year. It also includes a number of shocks in various localities on the Pacific coast which it was thought might not have \u27been recorded in other reports. No systematic examination of newspapers has been made, however, and some reports of earthquakes may have escaped notice

    Earthquakes in California in 1894

    The following report is a continuation of similar records, and brings the list up to the end of the year 1894. It contains accounts of all the shocks observed or felt on Mount Hamilton and all those reported to the Lick Observatory by letter, as well as newspaper reports of earthquakes occurring in the State during that year. Many newspapers have been examined, and this bulletin is largely made up from their reports. Some may have escaped notice. It has been the object especially to record earthquakes occurring in California, but a number of shocks are here recorded which do not properly belong in a record of California earthquakes, which have been included for fear they may have escaped other compilers. The records of the United States Weather Bureau and of the United States Light-House Board, together with the present list, will afford a fairly complete account of the California earthquakes of 1894

    Indians on the Upper Missouri. Message from the President of the United States, transmitting a report in regard to the expedition among the Indians on the Upper Missouri. March 24, 1856. -- Referred to the Committee on Indian Affairs and ordered to be printed.

    This Executive Document, dated March 24, 1856, also known as United States (US) House of Representatives Executive Document No. 65, consists of a message from US President Franklin Pierce, in which Pierce transmits, in obedience to [the US House of Representatives\u27] resolution of the 17th instant, a communication from the Secretary of the Interior, accompanied by a copy of the report of Superintendent [Alfred] Cumming, in regard to his late expedition among the tribes of the Indians on the Upper Missouri. In his report, Cummings reports on his trip up the Missouri for the purpose of distributing annuities to local tribes, describing his impressions of the tribes, their customs, temperament, relations with neighbors, etc., as well as the landscape, flora and fauna he encounters along the way.https://commons.und.edu/indigenous-gov-docs/1110/thumbnail.jp

    Turkish D-light : accentuating heritage values with daylight

    Get PDF
    Historic buildings have their own cultural identity, which is often related to their aesthetic qualities such as period characteristics (geometry, size, colour, form and shape), materials and construction. Daylight is one of the primary elements contributing to the distinctiveness of the visual environment of many historic buildings, but is rarely considered as one of the components that shape the character of a building when adaptive preservation schemes of historical buildings are planned. Many historic buildings were originally designed to accommodate activities different to their new use and preserving the quality of daylight that originally contributed to their visual identity is a challenging task. Maintaining the ‘day-lit appearance’ of a building can be particularly problematic if the building is to be used as a museum or a gallery owing to the artefacts’ conservation requirements. This work investigated the opportunities of maintaining the original ambient conditions of renovated historical buildings while meeting the required daylight levels of the proposed new use. The study utilised an annual daylight simulation method and hourly weather data to preserve daylight conditions in renovated historic buildings. The model was piloted in a Turkish bathhouse situated in Bursa, Turkey, that is currently under renovation. The simulation model produces 4483 hourly values of daylight illuminance for a period of a whole year using the computer program Radiance. It is concluded that daylight characteristics should be taken into account when developing a renovation scheme. With increasing pressure on valuing historic buildings in many parts of the world, the work reported here should be beneficial to those concerned with the conservation and adaptive reuse of historic buildings. The study findings could also be useful to those interested in predicting potential energy savings by combining daylighting and electric lighting in historic buildings
