In the past two centuries, cowbirds have increased in numbers and extended their range across North America, while many of the native songbird species whose nests they parasitize to raise their young have declined. This timely book collects forty essays by most of the principal authorities on the biology and management of cowbirds. The book's goals are to explore the biology of cowbirds, the threats they pose to host species and populations, and the management programs that are being undertaken to minimize these threats.

The book is organized into five sections, each with an extended editors' introduction that places the contributions in a broad, up-to-date setting. The sections cover:

• The changing abundance of cowbirds and the ways in which their numbers can be estimated.
• Host choice by cowbirds, the negative effects of cowbirds on particular host species, and the daily patterns of cowbird behavior.
• Behavioral interactions between cowbirds and specific host species.
• Patterns of cowbird abundance and host use across varying landscapes.
• Management programs designed to control cowbirds and protect threatened songbirds.

This volume contains 189 hitherto unpublished letters by Edwin Arlington Robinson. They were written between 1897 and 1930 to one of his first admirers, Edith Brower of Pennsylvania.

The letters begin when the twenty-seven-year-old poet writes gratefully to the stranger who has expressed appreciation of his first, privately printed, book of poems, The Torrent and the Night Before. Soon he was carrying on an intense correspondence, baring his soul—safely, he believed, because the woman he described as “infernally bright and not at all ugly,” with “something of a literary reputation,” was “too old to give me a chance to bother myself with any sentimental uneasiness.” (She was twenty-one years his senior.)

Continually reflecting his laconic, self-deprecating Yankee spirit, the letters range from the uncontrollable outpourings of a lonely individual, desperate for encouragement and understanding, to brief words of greeting or farewell. Without reserve, Robinson—who was eventually awarded the Pulitzer prize for poetry three times—confides his reactions to people and places, his thoughts about his own work, and his personal opinions of such writers as Browning, Dickens, Hardy, Moody, and Pater.

Mr. Cary has included Miss Brower’s unpublished memoir on the poet’s character and literary career, “Memories of Edwin Arlington Robinson,” and her penetrating review of The Children of the Night. In addition to an informative Introduction, he contributes full explanatory notes, a list of Robinson’s works, and an index.

Rapidly developing diagnostic and therapeutic methods involving direct contact with the human fetus—fetoscopy, fetal surgery, ultrasonic scanning— demand a precise knowledge of normal structural development during gestation. Toward achieving that goal of precision, Drs. Robert Shapiro and Franklin Robinson have created an atlas described by Richard L. Sidman as “a solid piece of research, executed with considerable esthetic as well as scholarly finesse, and [which] will serve as the definitive study on an important aspect of human fetal development.”

The authors have documented the early development of the human skull in terms of gross size, shape, and the behavior of the individual bones com posing the skull with reference to their ossification centers, ossification rates, and relationships. The data are presented in very high quality photographs and radiographs of the dried skull in several relevant orientations, low magnification color photomicrographs of well sectioned and stained specimens, and color photographs of an unusually fine series of transilluminated skulls prepared by the Spalteholz method. Line drawings are also presented to assist in interpretation.

The atlas is organized according to gestational age, and a tabular summary is given of the 63 specimens ranging in age from ten to forty fetal weeks.

This will be the basic normative standard reference for studies on develop mental skeletal disorders of the head and neck; it will be useful as well in the study of developmental brain diseases. Radiologists engaged in visualizing the fetus and diagnosing fetal diseases in situ by ultrasound, computerized tomography, and other methods will find this an invaluable tool.

The rise of the Mongol empire transformed world history. Its collapse in the mid-fourteenth century had equally profound consequences. Four themes dominate this study of the late Mongol empire in Northeast Asia during this chaotic era: the need for a regional perspective encompassing all states and ethnic groups in the area; the process and consequences of pan-Asian integration under the Mongols; the tendency for individual and family interests to trump those of dynasty, country, or linguistic affiliation; and finally, the need to see Koryo Korea as part of the wider Mongol empire.

Northeast Asia was an important part of the Mongol empire, and developments there are fundamental to understanding both the nature of the Mongol empire and the new post-empire world emerging in the 1350s and 1360s. In Northeast Asia, Jurchen, Mongol, Chinese, Korean, and Japanese interests intersected, and the collapse of the Great Yuan reshaped Northeast Asia dramatically. To understand this transition, or series of transitions, the author argues, one cannot examine states in isolation. The period witnessed intensified interactions among neighboring polities and new regional levels of economic, political, military, and social integration that explain the importance of personal and family interests and of Korea in the Mongol state.

Offering a new perspective on Zionism, Exiled in the Homeland draws on memoirs, newspaper accounts, and archival material to examine closely the lives of the men and women who immigrated to Palestine in the early twentieth century. Rather than reducing these historic settlements to a single, unified theme, Donna Robinson Divine's research reveals an extraordinary spectrum of motivations and experiences among these populations.

Though British rule and the yearning for a Jewish national home contributed to a foundation of solidarity, Exiled in the Homeland presents the many ways in which the message of emigration settled into the consciousness of the settlers. Considering the benefits and costs of their Zionist commitments, Divine explores a variety of motivations and outcomes, ranging from those newly arrived immigrants who harnessed their ambition for the goal of radical transformation to those who simply dreamed of living a better life. Also capturing the day-to-day experiences in families that faced scarce resources, as well as the British policies that shaped a variety of personal decisions on the part of the newcomers, Exiled in the Homeland provides new keys to understanding this pivotal chapter in Jewish history.
