This article is based on an address to the society for American Archaeology at its annual meeting on May 17, 1946 at Indianpolis. A following address by Dr. Waldo R. Wedel desalt with the chronology of central Plains cultures. As the two chronologies embraced a very considerable portion of the United States and were in rather remarkably close agreement, it was suggested by retiring editor Byers that they be published in this journal.

The two most important 19th-century books on archaeology in the United States both dealt with earthworks. The earlier of these two, Ancient monuments of the Mississippi Valley by Ephraim G. Squier & Edwin H. Davis, was the first volume published by the fledgling Smithsonian Institution, and is 150 years old this year. It presented, with lavish illustrations, information about hundreds of earthworks. Its principal argument was that the mounds had been built by an American race distinct from the historically known indigenes, no less and perhaps considerably more than 1000 years ago. This volume in no small measure catalysed the development of archaeology in the United States. Without Squier & Davis’ extensive documentation of the vast number, size, complexity and variety of earthworks, the later book might never have been commissioned or might have been conceived in far less ambitious terms.

This chapter examines the many ways in which loyalty became part of a struggle for property, a struggle that would have profound consequences for the shape of Reconstruction in the Mississippi Valley. The chapter examines how state-sponsored emancipation worked in lockstep with the wartime seizure of property to create an environment within which loyalty to the United States gave worthy individuals claim to their possessions and left disloyal traitors with the flimsiest of holds over their land, their homes, and the black laborers many once owned. African Americans seized on the language of loyalty to claim a meaningful freedom for themselves and knit their families together again. The twinned power of allegiance and property nearly proved the undoing of white supremacy in the state. In the claims and counterclaims of black and white alike, what emerged was potentially the most radical edge of American emancipation: a bold attempt to give to former slaves the property of their disloyal former owners. In this, the collective stepping back from the most revolutionary of Reconstruction measures also spelled the slow erosion of loyalty, leaving former slaves without the means to claim anything more than political rights.

Wheat blast is a devastating disease that was first identified in Brazil and has subsequently spread to surrounding countries in South America. In May 2011, disease scouting in a University of Kentucky wheat trial plot in Princeton, KY identified a single plant with disease symptoms that differed from the Fusarium head blight that was present in surrounding wheat. The plant in question bore a single diseased head that was bleached yellow from a point about one-third up the rachis to the tip. A gray mycelial mass was observed at the boundary of the healthy tissue and microscopic examination of this material revealed pyriform spores consistent with a Magnaporthe sp. The pathogen was subsequently identified as Magnaporthe oryzae through amplification and sequencing of molecular markers, and genome sequencing revealed that the U.S. wheat blast isolate was most closely related to an M. oryzae strain isolated from annual ryegrass in 2002 and quite distantly related to M. oryzae strains causing wheat blast in South America. The suspect isolate was pathogenic to wheat, as indicated by growth chamber inoculation tests. We conclude that this first occurrence of wheat blast in the United States was most likely caused by a strain that evolved from an endemic Lolium-infecting pathogen and not by an exotic introduction from South America. Moreover, we show that M. oryzae strains capable of infecting wheat have existed in the United States for at least 16 years. Finally, evidence is presented that the environmental conditions in Princeton during the spring of 2011 were unusually conducive to the early production of blast inoculum.
