AbstractSix major hypotheses have been advanced to account for ground slate industries containing knives, lance heads, and projectile points, found on opposite sides of the North American continent. Certain of these hypotheses assume genetic connections; others postulate separate sources and developments for such artifacts in the Northeast and North Pacific areas.A recent study of the cultures involved, chiefly Borden's (1962) Vancouver data, has indicated that: (1) ground slate artifacts made their initial appearance in both areas at about the same time; (2) the respective typologies are quite dissimilar; and (3) possible bone and/or chipped stone prototypes for certain of the specific ground slate forms exist in each area.These data suggest independent origins and developmental histories.

Austrian Minister

On September 26, 1786, Don Francisco de Miranda, adventurer and patriot, secured a passport from the Austrian Minister in Constantinople which enabled him to continue his “grand tour” to Russia. The nature of Miranda’s subsequent visit, and the extent to which his reception at the court of Catherine II influenced Spanish and Russian policy, assumes significance in the light of events on the North American continent immediately preceding and during his stay in Russia.

One New Species

Ten species of the genus Crepidotus are described from Hawaii. They are Crepidotus alabamensis, C. amygdalosporus, C. appalachianensis, C. applanatus var. globigera, C. avellaneus, C. citrinus, C. mollis, C. nephrodes, and C. rhizomorphus. One new species, C. bakerae, is proposed. Keys and distinctive characters of each species are provided. It is suggested that most of the species came from the North American continent.

Early Phases

During the Viking period, Norse seafarers from Greenland attempted to plant a settlement on the North American continent. This Vinland settlement faltered in its early phases and was not successful. Its failure may be best understood from the broader perspective of the Scandinavian expansion across the North Atlantic islands which began ca. AD 800. Adaptive shifts in the older North Atlantic colonies, geographical factors, and the resistance of Native Americans may have combined to doom this Western-most medieval colony.
