The first major attempt to employ the reflection method in California was made in 1931. The first results were disappointing, but by the early part of 1932 a prospect near Merced was successfully mapped. The correlation method was found to have limited applicability and the dip method was generally adopted. Most of the early work was performed with wide spacing of stations and lines since very close control was not considered necessary to discover the larger structural features which were then of greatest interest. As a result of this early reflection work several important oil fields were discovered among which are the Wilmington and Rio Bravo fields. A brief history of the discovery of these two fields is given and the seismic maps are compared with the later geologic maps compiled from well data.

THE eighteenth century was noted rather for the rise of new denominations than the union of old ones. Nevertheless it is not to be forgotten that attempts at union were made even though they were unsuccessful. It has taken nearly two hundred years for us in America to work out a plan of federation such as was attempted at Philadelphia in the early part of December, 1908. Federal Union was unknown, unthought of, in those early days. Organic union was the kind most generally considered. And this greatly increased the difficulties of forming church unions, as denominations were not generally willing to give up their peculiarities or their independence. I wish to speak of two efforts at church union especially connected with my own church, the German Reformed Church, leaving it for others to speak of other efforts that may have been made in the early history of America. In this age when church union is in the air it is certainly not unsuitable to study these early movements.

The Ten Section oil field, generally regarded as the first geophysical oil field discovery in the San Joaquin Valley of California, was found by Shell Oil Company, Incorporated by means of a reflection seismograph survey made in 1934–1935. The discovery well, Shell Oil Company, Incorporated’s K. C. L.-Stevens A-1, was completed in June, 1936. A map presenting results of reflection shooting before discovery and one from well data with contours on the top of the productive Upper Miocene “Stevens” sand are shown.

Original seismic maps based on the correlation method of reflection shooting are presented, together with a geological structure map. Cross sections show a comparison of the seismic and the well data. Results of a gravity‐meter survey are also shown.

Theuvenins Creek Field is located along the Wilcox producing trend in south‐central Tyler County, Texas. The field was discovered jointly by Sinclair Oil and Gas Company and the Atlantic Refining Company. The first seismic survey of the area was made in 1938. In 1942, a reconnaissance seismic survey was made using the spot correlation method. This work indicated anomalous conditions. In 1955, the area was detailed using a continuous seismic profile method. The seismic data were later reviewed, and the reviewed interpretation substantiated the existence of Wilcox structural closure. Based on seismic evidence, Atlantic and Sinclair spudded the Brown Fee No. 1 wildcat well on August 15, 1957. This well was completed on October 12, 1957 as the discovery well of the field. From an Upper Wilcox sand the well produced 279 barrels of oil per day. Subsequent drilling developed two producing sands in the Uppper Wilcox. A total of 38 producing wells have been drilled on the structure with no dry hole to date. To January, 1961, the total cumulative production from the field was 1.4 million barrels of oil.

The one important, indeed invaluable, source for the history of the council in the early-fifteenth century is the Proceedings and Ordinances of the Privy Council of England, 10 Richard II–33 Henry VIII, edited by Sir Nicholas Harris Nicolas and published by the Record Commission in seven volumes in the years 1834 to 1837, but in so far as the title of this work implies a formal and continuous record of proceedings it is misleading, for, unlike parliament, the council left no regular account of its activities. The Rolls of Parliament, even though their account of the proceedings is one-sided, official and incomplete, do at least record such bare facts as the dates of meeting, the names of the Speakers, and usually the dates of adjournment; but there are no similar rolls for the council. The phrase ‘privy council’ in Nicolas's title is also something of an anachronism, at least for the early part of the period covered. At this time the future privy council was generally known simply as the council or the king's council, although it was sometimes called the continual council to distinguish it from the larger body known to contemporaries as the great council. This distinctionis usually made in official records, but chroniclers often referred indifferently to either body as the council, and the differences are not now always apparent to us.

The report is based on the first results of the study "The History of the Evangelical Christians-Baptists in Ukraine", carried out in 1994-1996 by the joint efforts of the Department of Religious Studies at the Institute of Philosophy of the National Academy of Sciences of Ukraine and the Odessa Theological Seminary of Evangelical Christian Baptists. A large-scale description and research of archival sources on the history of evangelical movements in our country gave the first experience of fruitful cooperation between secular and church researchers.

Central Africa remained botanically unknown to the outside world up to the end of the eighteenth century. This paper provides a historical account of plant explorations in the Luangwa Valley. The first plant specimens were collected in 1897 and the last serious botanical explorations were made in 1993. During this period there have been 58 plant collectors in the Luangwa Valley with peak activity recorded in the 1960s. In 1989 1,348 species of vascular plants were described in the Luangwa Valley. More botanical collecting is needed with a view to finding new plant taxa, and also to provide a satisfactory basis for applied disciplines such as ecology, phytogeography, conservation and environmental impact assessment.

Portugal has port, Spain has sherry, Sicily has Marsala –– and California has angelica. Angelica is California's original wine: The intensely sweet, fortified dessert cordial has been made in the state for more than two centuries –– primarily made from Mission grapes, first brought to California by the Spanish friars. Angelica was once drunk in vast quantities, but now fewer than a dozen vintners make angelica today. These holdouts from an earlier age are each following a personal quest for the real. For unlike port and sherry, which have strict rules about their production, angelica never gelled into something so distinct that connoisseurs can say, ““This is angelica. This is not.”” This piece looks at the history of the drink, its foggy origins in the Mission period and on through angelica's heyday and down to its degeneration into a staple of the back-alley wino set. Several current vintners are profiled, and they suggest an uncertain future for this cordial.

This article discusses an international exhibition that detailed the recent history of African Americans in Pittsburgh. Methodologically, the exhibition paired oral history excerpts with selected historic photographs to evoke a sense of Black life during the twentieth century. Thematically, showcasing the Black experience in Pittsburgh provided a chance to provoke among a wider public more nuanced understandings of the civil rights movement, an era particularly prone to problematic and superficial misreadings, but also to interject an African American perspective into the scholarship on deindustrializing cities, a literature which treats racism mostly in white-centric terms. This essay focuses on the choices made in reconciling these thematic and methodological dimensions when designing this exhibition.
