U.S. agencies having responsibility in foreign assistance programs long have recognized the need for a handbook on horticultural crops in the Tropics. Information on the subject may be found in various scientific textbooks, treatises and papers. It is to fill the need for consolidated information in ready reference form that this Handbook on Tropical and Subtropical Horticulture is issued by the Agency for International Development in consultation with the U. S. Department of Agriculture. Based upon an extensive survey of available literature, this manual is designed for the use of US. A.I.D. technicians and contract personnel, and for Peace Corps volunteers engaged in rural development. It is written in layman's language so that it may be understood by the non-specialist who yet is called upon to work with farm families in solving their agricultural problems. Nevertheless, research workers and students also will find it of value because of its up to date and extensive bibliography. It also serves as reference and guide for teaching courses. In addition to U.S. A.I.D. and Peace Corps personnel, there are two other groups to whom this Handbook can be of great help. The one group is composed of missionaries living with rural people and concerned with agricultural education in the Tropics. Often lacking an agricultural background, they must search for practical information on tropical crops to help local farmers increase agricultural productivity. In the other group are employees of large agricultural companies. Some of these are foreign, others are local technicians. Perhaps their first aim is to promote the use of a specific agricultural chemical, for example, but since they have close contact with farmers, they are called upon often to answer questions pertaining to other phases of agriculture. There has been a dearth of agricultural research people in the Tropics and a shortage of funds for basic and applied research. In general the quality of research work has been good, but quantity and coverage are limited. The Handbook indicates in the first chapter those fields of endeavor where work is needed immediately. Major fruit, nut and tree crops are discussed in the second chapter with emphasis on such important points as spacing, pruning, fertilizing, budding, and disease and insect control. A few Temperate Zone fruits are included to stress that they can be grown only at higher elevations in the Tropics, due to chilling requirements. Crops are listed alphabetically and scientific names are given for reference purposes. The Handbook continues with a description of all major vegetable crops. Information is presented on seed storage, vegetable varieties, fertilizer recommendations, plant spacings, temperature requirements, soil and cultivation. Major diseases with their control are presented in a table for easy reference. Herbicides are being used extensively in temperate regions for weed control. They will come into more use in the Tropics in the future, especially if labor costs continue to increase. Accordingly, a table lists recommended herbicides for each crop. Likewise, a table is presented to indicate major insects and how they can be controlled. Pictures are included for identification purposes.
The moving or transplanting of trees and shrubs is an activity probably as old as mankind. Basically, the process of moving growing plants from one place to another is little changed from early times, but our increased understanding of the processes of nature through recent research and investigations in the broad fields of horticulture, arboriculture, and forestry, and the development of better machinery and equipment have brought about many improvements in the technique of moving trees and shrubs. Today, the moving of trees 12 to 18 inches in diameter is a matter of routine, and trees several times as large frequently are transplanted with success. The cost of such operations is relatively high and seldom in national park work is it justifiable, except under special conditions.The transplanting of small- to medium-sized trees and shrubs, however, is a constantly recurring activity in areas under Service jurisdiction, and it is to aid the planners and supervisors of such work that this bulletin is issued. Because of the varying conditions of climate, soil, temperature, species, etc., encountered in national park areas, it is impossible to lay down rigid rules for transplanting. The principles involved, however, are the same in Maine as they are in Texas, and it is hoped that a codification and explanation of some of these principles and descriptions of certain techniques will prove to be adaptable and of value under many of the various conditions encountered.
The purpose of this book is to provide guidance on ground improvement for civil works and military programs projects. It contains an up-to-date overview of ground improvement techniques and related considerations. It addresses general evaluation of site and soil conditions, selection of improvement methods, preliminary cost estimating, design, construction, and performance evaluation for ground improvement. This book should be used as a resource during planning, design, and construction for new projects as well as a reference to guide more detailed design efforts for modification of existing projects.Ground improvement is the modification of existing site foundation soils or project earth structures to provide better performance under design and/or operational loading conditions. Ground improvement techniques are used increasingly for new projects to allow utilization of sites with poor subsurface conditions and to allow design and construction of needed projects despite poor subsurface conditions which formerly would have rendered the project economically unjustifiable or technically not feasible. More importantly, such techniques are used to permit continued safe and efficient operation of existing projects when major deficiencies become evident or where existing projects are likely to be subjected to loads greater than original design or as-built capabilities.
This manual provides (a) guidance on the design and construction of conduits, culverts, and pipes, and (b) design procedures for trench/embankment earth loadings, highway loadings, railroad loadings, surface concentrated loadings, and internal/external fluid pressures.Reinforced concrete conduits and pipes are used for dams, urban levees, and other levees where public safety is at risk or substantial property damage could occur. Corrugated metal pipes are acceptable through agricultural levees where conduits are 900-mm (36-in.) diameter and where levee embankments are not higher than 4 m (12 ft) above the conduit invert. Inlet structures, intake towers, gate wells, and outlet structures should be concrete, or corrugated metal structures may be used in agricultural and rural levees. Life cycle cost studies are required where corrugated metal pipes are used.

Tables report historical averages of crop area, yield, and production. Coverage includes major agricultural regions and crops of coarse grains, winter and spring wheat, rice, major oilseeds, sugar, and cotton. World maps show the normal developmental stage of regional crops by month.
This book tries to describe what an intelligent person would have witnessed in ancient Athens if by some legerdemain he were translated to the fourth century B.C. and conducted about the city under competent guidance. The year 360 B.C. has been selected as the hypothetical time of this visit, not because of any special virtue in that date, but because Athens was then architecturally almost perfect, her civic and her social life seemed at their best, the democratic constitution held its vigor, and there were few outward signs of the general decadence which was to set in after the triumph of Macedon. At the time of original publication in 1925, William Stearns Davis was Professor of Ancient History, University of Minnesota.

An historical study of the role of the mulatto in American society, with a discussion of the mixing of races in other parts of the world.Edward Byron Reuter (1880-1946) received his doctoral degree in sociology from the University of Chicago in 1919 for this dissertation. He served (in 1933) as the 22nd President of the American Sociological Society.
A memoir by Russian explorer Vladimir Arsenyev, covering his trips in 1902, 1906, and 1907 as the first European to explore remote portions of Siberia. Dersu Uzala was his native guide on these trips. The book describes their adventures deep in the wilderness. It is the source for the Kurosawa movie of the same name. A great story of exploration.
The two representative Frenchmen of the eighteenth century are Voltaire and Mirabeau. Voltaire was the last great influence of the old order, and Mirabeau the first of the new. Voltaire, more than any other one man, undammed the torrent of Revolution. Mirabeau used all the strength of his mighty genius to turn those rushing waters into the channel of use, of wisdom, and of safety. These two notable men have inspired the present biographer, who has the distinction of having written what may be regarded as the definitive life of each. The Life of Voltaire is, like The Life of Mirabeau, a penetrating study of character combined with a dramatic conception of Voltaire's role in history. S. G. Tallentyre is also the author of The Life of Mirabeau and The Friends of Voltaire.

The Conquest of Bread is Peter Kropotkin's most detailed description of the ideal society, embodying anarchist communism, and of the social revolution that was to achieve it - a study of the needs of humanity, and of the economic means to satisfy them.
Originally published in 1859, the author was a former American Vice Consul in Nicaragua. Some of the press comments of the time were: "The work pursues a natural order - overlooking nothing of interest - giving glowing accounts of the country, its scenery and resources - doing justice to the history of the country and its revolution and leaders, and present inhabitants. ..." - Independent Civilian "During the filibustering career of Walker, he was a resident of Nicaragua, and saw many of the movements of the belligerents. His information is copious and thorough. The style is clear and lively, and the reader finds no difficulty in taking in the scenes described, and the events related. Whoever is interested in the affairs of Nicaragua, will find this book an indispensable necessity." - Philadelphia Dispatch
A storage area network (SAN) is a network of storage devices that are connected to each other and to a server, or cluster of servers, which acts as an access point to the SAN. The value of storage as a corporate asset has risen dramatically. This text makes the world of storage accessible, even to a novice in the field. It is a practical guide to implementing a complex technology.
The dawn of aviation began with lighter-than-air craft and gliders. They were in the forefront of what eventually led to the Wright brothers' activities at Kitty Hawk. The Navy's early use of lighter-than-air craft may be traced back to the American Civil War. However, it was a short-lived affair and these LTA possibilities were not pursued after the war. With the advent of airplanes in naval service, the Navy again turned its interest to lighter-than-air craft. The Navy's lighter-than-air program blossomed and its fleet of airships became the largest the world has ever seen. During the era of the giant rigid airships, the Navy built some of the largest airships in the world. Many achievements were recorded by the Navy's LTA branch and new records were set, records which still remain unbroken today. This monograph is intended to provide an overview of the Navy's involvement with balloons, airships and their operations, which shows their failures and accomplishments and their contributions to the Navy's mission of guarding the sea lanes of America. It is not an in-depth study of the LTA program, but provides an overall look at the history of LTA in the Navy. Various aspects of the LTA program have had extensive coverage, especially the rigid airship era; however, the entire history of LTA in the Navy has not been told under one cover. The Navy's LTA program technically ended in the 1960s. But the evolutionary trends that can be seen in history could possibly bring back certain functions of LTA and make them viable in today's world of supersonic flight and space travel.
An Ocean Blueprint for the 21st Century calls for a new governance framework, more investment in marine science and a new stewardship ethic by all Americans - all within the context of an ecosystem-based management approach - to halt the decline of this nation's oceans and coasts. In total, the U. S. Commission on Ocean Policy put forward 212 recommendations for a new national ocean policy in the report. The value of the oceans and coasts to the nation is immense and their full potential remains unrealized. Over half the U.S. population lives in coastal watershed counties and roughly one-half of the nation's gross domestic product ($4.5 trillion in 2000) is generated in those counties and in adjacent ocean waters. A comprehensive and coordinated national ocean policy requires moving away from the current fragmented, single-issue way of doing business and toward ecosystem-based management. This new approach considers the relationships among all ecosystem components, and will lead to better decisions that protect the environment while promoting the economy and balancing multiple uses of our oceans and coasts.
The purpose of this dictionary is to give an account of everything that relates to Christ - His Person, Life, Work, and Teaching. It is in a sense complementary to the Dictionary of the Bible, in which, of course, Christ has a great place. But a dictionary of the Bible, being occupied mainly with things biographical, historical, geographical, or antiquarian, does not give attention to the things of Christ sufficient for the needs of the preacher, to whom Christ is everything. This is, first of all, a preacher's dictionary. The authors of the articles have been carefully chosen from among those scholars who are, or have been, themselves preachers. And even when the articles have the same titles as articles in the Dictionary of the Bible, they are written by new men, and from a new standpoint. It is thus a work which is quite distinct from, and altogether independent of, the Dictionary of the Bible. It is called a Dictionary of Christ and the Gospels, because it includes everything that the Gospels contain, whether directly related to Christ or not. Its range, however, is far greater than that of the Gospels. It seeks to cover all that relates to Christ throughout the Bible and in the life and literature of the world. There will be articles on the Patristic estimate of Jesus, the Medieval estimate, the Reformation and Modern estimates. There will be articles on Christ in the Jewish writings and in the Muslim literature. Much attention has been given to modern thought, whether Christian or anti-Christian. Every aspect of modern life, in so far as it touches or is touched by Christ, is described under its proper title. James Hastings (1852-1922) was a distinguished scholar and pastor. He was founder and editor of the Expository Times and is also well known for editing the five-volume Dictionary of the Bible, as well as the Encyclopaedia of Religion and Ethics, the Dictionary of Christ and the Gospels, and the Dictionary of the Apostolic Church.

It is widely believed that monopoly control, based on violence, corruption or risk-spreading, is characteristic of markets for illegal goods and services, such as marijuana and bookmaking. This essay examines the effects on the organization of a market arising from changing the status of a good or service from legal to illegal.In general, it can be shown that illegal enterprises are likely to be smaller than their legal counterparts. The most important reasons for this are the lack of external credit markets, itself a consequence of the non-existence of audited records, the lack of court enforceable contracts, and the need to restrict knowledge of participation in the enterprise. The inability to advertise or to create goodwill for the enterprise itself, as opposed to goodwill for its agents, is also significant. Corruption is likely to affect the organization of the market only under special circumstances, where there is a single agency which monopolizes enforcement. Though that condition held for most illegal markets thirty years ago enforcement now is fragmented and overlapping, which inhibits an agency from granting a monopoly franchise.The introduction of violence does not in general change this result. The use of violence to acquire market power can occur only where there is a ready focus for that violence. Most illegal markets lack either time or space consistency that would permit exclusion of competition. Some comments about the optimal use of violence are offered.The final section offers some analysis of the plausibility of using illegal market enforcement as an instrument of organized crime control. There have been systematic changes in the set of opportunities available to organized crime members; illegal markets no longer are so central to the power and income of organized crime. The shift from gambling to narcotics markets has also weakened the link between organized crime and illegal markets.

This book, by Dr. R. Craig Nation, was written to address the need for a comprehensive history of the Balkan wars provoked by the collapse of the Yugoslav Federation in 1991. These wars, and the instability that they have provoked, became preoccupations for international security management through the 1990s. After an initial phase of distancing and hesitation, Balkan conflict drew the United States and its most important European allies into an open-ended commitment to peace enforcement, conflict management, and peace-building in the region, importantly supported by the U.S. Army. These efforts are still underway, and significant tensions and potential flashpoints remain in place within former Yugoslavia and the entire Southeastern European area. The lessons learned from the new Balkan wars, and the successes and failures of U.S. and international engagement, provide a significant foundation for future efforts to manage intractable regional conflict. Dr. Nation's work has been supported by a research grant provided by the U.S. Army War College, and is published under the auspices of the Strategic Studies Institute. The Army War College's primary mission is to prepare new generations of strategic leaders to assume positions of responsibility within the U.S. armed forces and civilian arms of the national security system. That mission includes a serious confrontation with the most pressing security issues of our time, to include the nature of contemporary armed conflict and the changing nature of war itself. The Balkan conflict of the 1990s, as a case study in state failure and medium intensity warfare, international conflict management and intervention, and U.S. military engagement, provides an excellent framework for asking basic questions about the dynamic of international security at the dawn of a new millennium. War in the Balkans, 1991-2002 is intended to provide a foundation for addressing such questions by surveying events in both contemporary and larger historical perspectives and posing preliminary conclusions concerning their larger meaning. There will, regretfully, be other situations comparable in broad outline to the violent decline and fall of socialist Yugoslavia. The policies of the international community in the Yugoslav imbroglio have been criticized widely as ineffective. However, in the end, after years of futility, the conflict could be contained only by a significant international military intervention spearheaded by the United States, and a long-term, multilateral commitment to post-conflict peace-building. Few would wish to pose the outcome as a model to be emulated, but it should be a case from which we can learn. DOUGLAS C. LOVELACE, JR. Director Strategic Studies Institute
