In the literature on forest entomology there has been considerable confusion regarding the true identity of the two species of Dioryctria feeding on spruce in North America. Superficially the adults of these species resemble each other so closely that the one is easily mistaken for the other. In seasonal history and habits, however, they differ very materially.

The concept of “brain drain” is in its origins a nationalistic concept, by which is meant a concept that visualizes economic and cultural welfare in terms of the welfare of the residents of a national state or region, viewed as a totality, and excludes from consideration both the welfare of people born in that region who choose to leave it, and the welfare of the outside world in general. Moreover, though the available statistics are far from adequate on this point, there is generally assumed to be a net flow of trained professional people from the former colonial territories to the ex-imperial European nations, and from Europe and elsewhere to North America and particularly the United States. The concept thus lends itself easily to the expression of anti-colonial sentiments on the one hand, and anti-American sentiments on the other. The expression of such sentiments can be dignified by the presentation of brain drain as a serious economic and cultural problem, by relying on nationalistic sentiments and assumptions and ignoring the principles of economics—especially the principle that in every transaction there is both a demand and a supply—or by elevating certain theoretical economic possibilities into presumed hard facts.

The five hundredth anniversary of the Columbian discovery of America is upon us, and with it the obligation to assess existing interpretations of the significance of that voyage and the establishment of permanent links between the Old and the New Worlds. The most influential of the several schools of interpretation are, on the one hand, the newest and analytic, and the other, the classic and bardic. The former is for many recondite and discomforting. The latter, the one most often taught, dramatized, and believed in North America, is for most as comfortable as an old pair of slippers. We learned it at primary school.

The emergence of the trade paperback in the 1980s crucially transformed the way in which Australian literature was received in North America. The publication history of Patrick White on the one hand and Glenda Adams and Peter Carey on the other shows how younger writers actually made more of a cultural impact, despite White’s Nobel Prize, because the form in which they met the reading public was one freed from the modernist binary between high and low culture. The 1980s saw the emergence of a more globalized and more culturally pluralistic world—though also one much more pervaded by multinational capital—in which Australian writers flourished.

The warfare of colonial and revolutionary North America, from European–native conflicts and the Seven Years’ War to the American Revolutionary War and the War of 1812, has only recently come to be considered in gendered terms. The roles of both women and men in North American warfare underwent enormous changes from the last quarter of the sixteenth century to the first quarter of the nineteenth. Two major themes are at the center of this chapter: on the one hand, the theme of the contested and changing constructions of military masculinity of Native Americans, British, and French white settlers and the British and French armies that were brought to North America especially in the context of the Seven Years’ War; and on the other hand, the theme of women’s different and changing involvement in warfare, which is related to the contested and changing representations of femininity in the different war societies.

Research on this topic in Europe and North America has reached a new stage. Prior to 1970, historians told a story of progress in which modern individuals gradually gained mastery of emotions. After 1970 this older approach was put into doubt. Since 1990 research into the history of emotions has increasingly relied on a new methodology, based on the assumption that emotion is a domain of effort, and that it is possible to document variance between emotional standards, on the one hand, and the greater or lesser success of individuals in conforming to them, on the other. Emotional standards are now assumed to display a history that is not progressive, but reflects distinctive features of each period.

Although current theories of diaspora argue for a break between an older irrevocable migration from one nation to another and a new transnational movement between host country and birthplace, research on nineteenth- as well as twentieth-century North America demonstrates that earlier migration also had a transnational dimension. The cultural consequences of this two-way traffic include syncretic performance forms, institutions, and audiences, whose legitimacy depended on engagement with but not total assimilation in local conventions and on the mobilization of touristic nostalgia in, say, Cantonese opera in California or Bavarian-American musicals in New York, to appeal to nativist and immigrant consumers. Today, syncretic theatre of diaspora is complicated on the one hand by a theatre of diasporic residence, in which immigrants dramatize inherited conflicts in the host country, such as Québécois separatism in Canada, along with problems of migrants, among them South Asians, and on the other by a theatre of non-residence, touring companies bringing theatre from the home country, say India, to ‘non-resident Indians’ and local audiences in the United States.

It is a singular coincidence that in a former communication to this Magazine (Vol. VI., p. 1) I described, among other Coniferous fruits, two from the Gault at Folkestone, the one the cone of a pine, and the other of a Wellingtonia, and that in this communication I propose to describe two hitherto unknown fruits from the same deposit and found at the same locality, belonging also the one to a Wellingtonia and the other to a pine. Although the small pinecone already described (Pinites gracilis) differs in form and in the arrangement of the scales from any known cone, recent or fossil, it is more nearly related to that group of the section Pinea, the members of which are now associated with the Wellingtonias in the west of North America, than with any other member of the great genus Pinus. I, however, hesitated to refer to this interesting fact, because the occurrence of the two cones in the Gault might have been due to their being accidentally brought into the same silt by rivers having widely separated drainage areas. And it is easier to keep back generalizations based on imperfect data, than to suppress them after publication, when in the progress of investigation they are shown to be false. But I have now to describe a second pinecone more closely related to the Californian species of Pinea, and with it a new species of Wellingtonia. These surely point with tolerable certainty to the existence of a Coniferous vegetation on the high lands of the Upper Cretaceous period having a fades similar to that now existing in the mountains on the west of North America, between the thirtieth and fortieth parallels of latitude. No fossil referable to Sequoia has hitherto been found in strata older than the Gault, and here on the first appearance of the genus we find it associated with pines of the same group that now flourish by its side in the New World.

The following investigation was commenced, in the first place, to provide information for class use, for, in spite of the fact that thousands of specimens of Squalus acanthias and S. sucklii are used every year in North America, there appears to be no satisfactory account of the blood vascular system of either species available. As the work proceeded, various problems arose which necessitated references to the conditions in other species and the preparation of more detailed dissections than are usually made in class work. It is well known that there is considerable confusion in the nomenclature employed by different authors for even some of the main vessels, and it was soon evident that this is not merely individual preference but, in part, due to a more fundamental lack of agreement as to the precise morphological significance of the vessels themselves. More recent embryological investigations by other workers have, we consider, given a key to the solution of the most important of these problems and have shown that, in so far as the blood-vessels are concerned, the Elasmobranchs lie closer to the other gnathostomatous vertebrates than is generally recognised, and indeed furnish a primitive and generalised type. The time seemed ripe, therefore, to provide a connected account of the vascular system in an Elasmobranch, viewing it in the light of the researches just referred to, and of what is known of the distribution of the various vessels in the sub-class in general. It was hoped that this would provide an epitome that would serve as a basis for future work in the sub-class, and also for comparison with the conditions in higher vertebrates.

Plant-based diets are often perceived as being antithetical to Indigenous interests in what is today colonially known as Canada. This perceived antithesis hinges on veganism's rejection of the consumption of animals. This apparent antithesis, however, is a misperception that a reframing of ethical veganism can help correct. This article argues that veganism's objection to dairy should be underscored as a central concern of ethical veganism. Such emphasis not only brings into view the substantial alignment between plant-based diets and Indigenous worldviews, but also highlights the related goals of decolonization and reconciliation in Canada. Veganism, in reality, rejects a practice (dairy farming) that was constitutive of settler colonialism in North America and which still promotes colonial familial ideologies while constructing Indigenous peoples and other non-Europeans (who disproportionately cannot tolerate lactose) as abnormal. Veganism – along with vegetarianism – shares the general respect for animals and interspecies relations (along with a concomitant disavowal of human exceptionalism) that many Indigenous legal orders in Canada promote. Yet, despite this shared disavowal of a principal colonial ideology, the tight correlation between hunting and Indigeneity on the one hand, and veganism and vegetarianism and an objection to killing animals on the other, makes veganism's contributions to decolonization and reconciliation difficult to see. By framing veganism as a critique of the dairy industry, however, the associations that veganism has with decolonizing ends are not clouded by these overpowering correlations, helping to bring into view even vegetarianism's contributions toward these ends.

The transarctic flights of 1926 and 1928 demonstrate the possibility of establishing communication by air across the Arctic regions between Europe, on the one side, and North America and the Far East on the other. Quite aside from the saving of time owing to shorter distance, the establishment of such communication presents considerably less diiSculty than air communication over the Atlantic: a conclusion derived from the transatlantic flights of the last three years. The experience of the airship Italia in May, 1928, does not at all nullify this conclusion. It serves merely to show that the organization of transarctic communication requires special prearrangements, such aa wireless stations, meteorological stations, landing-places, air-bases, the construction of which on the shores, islands, and even on the ice of the Arctic Ocean, appears to be quite feasible. The necessity for such stations has aroused in the governments of the North countries an increased interest in the Arctic regions which heretofore has been restricted to scientific circles.
