We published in our July issue (LIII, I48–9) comments by Dr Talbot of the University of Leeds challenging Robert Raikes's views on this subject, and we now print comments from Dr Sutton, Department of Archaeology, University of Ghana. We think that perhaps this discussion on the environmental history of the Sahara and Sahel has, by now, been sufficiently aired in our pages.

There is a long history of interest in the study of extinct populations, sometimes called “prehistoric demography” or “archaeological demography.” Most studies have focused on regional population size and trends through time and their explanation. Analyses of a single population at one community are rare.This paper discusses one effort at assessing the dynamics of population at one prehistoric community, the Grasshopper Pueblo, located in east-central Arizona. A long range program of archaeological research is being conducted at the site by the University of Arizona through the Archaeological Field School. This program is sponsored jointly by the Department of Anthropology and the Arizona State Museum and has been supported by the National Science Foundation since 1965.The Grasshopper Ruin, a fourteenth century pueblo, is an example of what some have called “Late Mogollon” or “Prehistoric Western Pueblo” culture. It consists of several main room clusters separated by a presently intermittent stream and surrounded by smaller groupings of rooms. There are approximately 500 rooms at the site. Space does not permit a discussion of the range of problems that we are attempting to solve in our research nor the sampling design. But one aspect of our work, the “Cornering-Growth Project,” has provided us with the relative construction sequences for all the rooms at the community. These data provide a basis for a study of population dynamics.

Between July 23 and July 25, 2014, the University of Montevideo hosted the Fourth Jornadas Internacionales de Historia del Paraguay, with sponsorship from the Universities of Georgia, Köln, and Rennes 2. Organized by Thomas Whigham and Juan Manuel Casal, the conference included 45 presenters and 70 attendees traveling to the Uruguayan capital from the United States, Germany, Spain, Italy, Paraguay, Brazil, Chile, Uruguay, and Paraguay. Students from both the National and Catholic Universities of Asunción also took part with one of their number, Claudio José Fuentes Armadans (Universidad Católica), providing an interesting presentation on the history of the Liberal Party. First-time contributors to the conference included Carlos Gómez Florentín (SUNY Stony Brook), who discussed the environmental history of the hydroelectric complex at Itaipú, and Justin Michael Heath (University of Texas, Austin), who traced the evolution of frontier security in the early Jesuit missions. The Jornadas also benefited from repeat contributors, including Ignacio Telesca (Universidad Nacional de Formosa/CONICET), who analyzed the historical content of Paraguayan textbooks in the late nineteenth and early twentieth centuries, and Bridget María Chesterton, who discussed how the “sweet herb” ka’a he’e (stevia) has affected markets and habits of consumption in more recent times.

The U-Pb analysis of zircons from two independent leucosome bodies belonging to the paragneiss of the Higher Himalayan Crystallines Sequence (HHCS) in the Everest region of eastern Nepal Himalaya was carried out using laser ablation-multi collector inductively coupled plasma-mass spectrometry (LA-MC-ICP-MS) at the University of Arizona, Tucson, USA. The analysis of zircons from sample 07EVT3 forms a discordia with upper and lower intercepts at 478±25 and 21.5±4.1 Ma with concordant ages of 488.5±9.2 and 20.9±0.9 Ma for cores and rims, respectively. Similarly, the analysis of zircons from sample U1206 forms a discordia with upper and lower intercepts at 515±20 and 34.8±2.7 Ma, and provides concordant ages of 463.9±10.9 and 24.6±0.6 Ma for cores and rims, respectively. No inherited zircon grains with older ages were found indicating that almost all these zircons must have formed along with the leucotomies during the ca. 500 Ma metamorphism of the protoliths. The high U/Th ratio, i.e. average 11.0 for zircons from sample 07EVT3 and 253.6 for sample U1206 also support a metamorphic origin of the zircons. The occurrences of zircons in the ca. 500Ma leucosomes in the HHCS strongly points that rocks in the Himalayan area had undergone to a high-grade metamorphism during the late Pan-African time. We call this metamorphism as the Proto himalayan metamorphism. More studies along this line will help to better understand and constrain the Pan-African orogenic history of the Proto-Himalayan Orogen within the Peri-Gondwana Orogenicterrains.
