AbstractThe number of predators inhabiting nests of Hyphantria cunea Drury was recorded annually for 13 years in four areas in New Brunswick and two areas on the coast of Nova Scotia. The most common groups were the pentatomids and spiders, which sometimes reproduced within the nests, but the mean number per nest was low in relation to the number of H. cunea larvae in the colonies. The rate of predation on fifth-instar larvae was low. Small or timid predators appeared to prey largely on moribund larvae or small saprophagans during the principal defoliating instars of H. cunea.No relationship could be detected between the number of larvae reaching the fifth instar and the number of predators in the colony; nor could any functional or numerical response of the predators to either the initial number of larvae per colony or the population density of colonies be found. It is concluded that the influence of the nest-inhabiting predators is small and relatively stable, and may be treated as a constant in the development of models to explain the population dynamics of H. cunea.H. cunea is a pest in parts of Europe and Asia, where it has been accidentally introduced from North America. The introduction to other continents of the North American predator, Podisus maculiventiis (Say), is discussed briefly.

Sedimentological and petrographical data obtained from five sections located north and south of the Caledonian Highlands in southeastern New Brunswick demonstrate the existence of three main till units and one glaciofluvial unit, which have been grouped in four distinct lithostratigraphic units. The lower till was deposited by a glacier that overrode the Caledonian Highlands from northwest to southeast and advanced as far as Nova Scotia during Middle(?) to Late Wisconsinan times. The overlying middle till from the north provides evidence that ice continued to advance across the Highlands from northwest toward southeast and then was partially overwhelmed by another glacier that was advancing southwest along the southern border of the Highlands: this glacier deposited a coeval middle till. During Late Wisconsinan deglaciation, ice separated into two masses: a residual ice cap with radial outflow from the Highlands; and a lobe in the Chignecto Bay, retreating toward the northeast. The existence of a plateau ice cap is demonstrated by the presence of till and glaciofluvial deposits in the upper part of all surveyed sections, and is supported by the sequence of ice flow patterns recorded by striae and the centrifugal distribution of meltwater flow indicators. The weak development of soils, the fresh appearance of till and morainic landforms, and the lack of periglacial features throughout the area, especially on the Highlands, all favour the interpretation that the Caledonian Highlands were not a nunatak during the glacial maximum of the Late Wisconsinan Substage.

Diverse conodont faunas recovered from the Grog Brook Group in northwestern New Brunswick indicate a Late Ordovician, probably Gamachian, age. The conodonts are of mixed provincial affinity including components of the North Atlantic Province (e.g., Hamarodus, Icriodella, Periodon, and Protopanderodus) and taxa representing shallow (e.g., Rhipidognathus) to deeper water environments (e.g., Phragmodus) in the Midcontinent Province. Elements of Amorphognathus ordovicicus Branson and Mehl numerically dominate the faunas that together with sparse representatives of Gamachignathus ensifer McCracken, Nowlan and Barnes suggest a latest Ordovician age. The beds from which the conodont faunas have been recovered are interpreted as distal debris flows that originated at the basin margin and brought Midcontinent Province conodonts down the slope to mix with indigenous North Atlantic Province faunas. The faunas are correlative with those from the Matapedia Group (previously thought to overlie the Grog Brook Group) and their occurrence suggests at least partial lateral equivalence of the two units.The conodonts recovered are only slightly thermally altered. Two alternative hypotheses are proposed to explain the juxtaposition of relatively unaltered conodonts of the Grog Brook Group and highly altered forms from the Matapedia Group. The first suggests that thrust faulting took place in the Late Ordovician – Early Silurian and that this process and later normal faulting account for the unusual distribution of conodont colour alteration. The second possibility is that the strata of the Grog Brook Group in the section examined were deposited on a structural high and overlain by little or no sediment of the Matapedia Group; however, such a structural high must have had access to a source of Midcontinent Province conodonts. Acadian thrusting then brought higher grade Matapedia Group strata into contact with this part of the Grog Brook Group.

An outbreak of the European spruce sawfly, Diprion hercyniae (Htg.), was discovered in the Gaspé Peninsula in 1930. By 1938, heavy infestations had developed west of the Gaspé Peninsula in Quebec, throughout New Brunswick and northern Maine, and in parts of Vermont and New Hampshire. Moderate to light infestations occurred through all other parts of the spruce forests of this region and extended from Nova Scotia, to the north shore of the St. Lawrence River, and west to Ontario.

This chapter highlights the troubles that Sam Whiting encountered before and after he arrived in Nassau. It presents Whiting's depressing observation he had made in his short time in Nassau: “There is a strong feeling in favor of the rebellion army among British officials and merchants.” The chapter also introduces merchant Henry Adderley, the soon-to-be most powerful man in the Bahamas. Though it was early in the game, Whiting had already recognized one of the key features of the way Adderley and others would operate. By using his pre-war connections in ports like Baltimore, Philadelphia, New York, Saint John, New Brunswick, and Halifax, Nova Scotia, Adderley would secure goods from the North and from England for shipment to the Confederacy and use these ports as false destinations on the manifests of the ships he sent to Charleston, Wilmington, and Savannah. Ultimately, the chapter illustrates the importance of Lewis Heyliger in Nassau. It analyzes the critical part he played in the Great Carnival and the business dealings he made in the Bahamas.

Two hundred thirty-five oriented cores were taken in a stratigraphic sequence of 575 m of red sediments from the Namurian Maringouin and Shepody formations. These samples were taken from the south-dipping limb of the Maringouin Anticline on the Maringouin Peninsula in eastern New Brunswick. An additional 59 samples of the Maringouin and Shepody formations were taken from the north-dipping limb for separate fold tests. Progressive thermal demagnetization to temperatures as high as 700 °C permitted the resolution of an intermediate-temperature, syn-folding B component and a high-temperature, pre-folding C component. The C-component mean for the Maringouin Formation yields a north paleopole at 32.4°N, 121.3°E. The Shepody Formation mean yields a paleopole at 35.7°N, 124.3°E. The circles of confidence (α95) for the Maringouin and Shepody formations are 3.8 °and 4.6°, respectively. Plotting sample polarity versus stratigraphie position yields the first coherent magnetic stratigraphy from the late Paleozoic of North America, with five discrete reversed-polarity and five discrete normal-polarity zones. The magnetic field in Namurian times had approximately 50% normal and 50% reversed polarity.
