An agricultural bulletin describes the nine species of May beetle in Arizona, with maps indicating the distribution of the insect's host plants throughout the state.

Agriculture was the basis of the Egyptian economy when Muḥammad 'Alī, "Founder of modern Egypt," was appointed governor of Egypt by the Ottoman sultan in 1805. Dr. Rivlin's purpose is to discover if Muḥammad 'Alī had a well-conceived agricultural policy of lasting significance for the development of Egyptian institutions. The conclusion reached after careful analysis of the problem from every facet is that far from having an agricultural policy per se, Muḥammad 'Alī merely utilized the agricultural wealth of Egypt for the purposes of personal aggrandizement and the attainment of a position of great power and independence for himself and his descendants within the Ottoman empire. The measures taken by Muḥammad 'Alī affecting land tenure replaced one class of landholders by another to the detriment of the peasant class and the religious institution. Although the Pasha can be credited with changing the Egyptian economy from a subsistence to a cash crop economy by the investment of capital in the development of agriculture, the financial benefits gained thereby accrued primarily to the Pasha himself. Instead of using these profits for economic purposes, Muḥammad 'Alī embarked upon a program of military adventurism that eventually undermined the economic life of the country and brought only limited political gains to Egypt. Muḥammad 'Alī's domestic policies established the social and economic pattern which prevailed until the Egyptian Revolution of 1952 and are largely responsible for many of Egypt's present problems. Dr. Rivlin's study is of major importance to students of the contemporary Egyptian scene, and should serve as an object lesson for present planners in underdeveloped countries. -- from dust jacket.

Groenveld attempted to show the magnitude of investments in agriculture, which were necessary to meet the increasing world demand for food. The formula S = K/Y (ΔN +ΔH) was assumed as a description that for a community the proportion of national income saved and invested must equal the product of proportional increase in population plus increase in income per head, and of the capital coefficient. Thus ensued the problem of allocating investments in agriculture and other sectors of the economy. In private investment decisions involved many people. For public investment decisions were usually central. But public complemented private investment. The figures for future demand for food were based on population size and estimated population growth, income per head and expected increase of it and income elasticity of food costs. Changes in supply through rise in production from an increase in productivity were distinguished from changes through enlargement of agricultural area. Extrapolation of production from the period 1950-60 until the year 1980 showed that investments in Asia (other than China and the Soviet Union), Africa and Latin America should be about 10% higher to keep pace with demand for agricultural products. Groenveld believed the solution could be to raise public investment, which he then estimated to be about the same size as the private investments.

El objetivo general es establecer bases que permitan realizar cambios en las actividades actuales de los agentes agrícolas para lograr un uso más efectivo de su tiempo de trabajo. Se tomó una muestra de seis agentes agrícolas, utilizando la técnica del muestreo estratificado al azar. Cuatro de estos agentes son ingenieros agrónomos y dos peritos agropecuarios. Tres de los seis agentes han recibido adiestramiento en extensión agrícola. Para la determinación del uso actual del tiempo se utilizó una "guía de observaciones", que permitió efectuar anotaciones cada cinco minutos de los siguientes tópicos: donde estaba el agente, con quien, que hacía, número de asistentes, distancias a la agencia y observaciones generales. Los niveles académicos, entrenamiento en extensión y experiencias del personal directivo del Servicio de Extensión, son más altos que en los agentes agrícolas. Los agentes invierten la mayor parte de su tiempo en la oficina y poco tiempo en las fincas y hogares de agricultores. El tiempo que invierten en actividades no educativas (64%) es muy alto con relación al tiempo en actividades educativas (36%). El 72% de los informantes consideran que los agentes no hacen un uso eficiente de su tiempo. La mayor parte de los informantes consideran que el establecimiento de un patrón de uso del tiempo, los cursos de adiestramiento en extensión, visitas de supervisión, medios de transporte y comunicación adecuados, son factores que ayudarían a los agentes para hacer un uso más efectivo de su tiempo. | The general objective is to establish a basis which will permit changes in present activities of the agricultural agents to obtain the most effective use of his work time. A sample of 6 Agricultural Agents was taken at random. Four of these Agents are " Ingenieros Agrónomos"(Agricultural Faculty graduates) and two "Peritos Agrónomos" (non-graduates). Three of the six Agents have received training in agricultural extension. To determine the use of time, an observation guide was used which allowed checking the following topics every five minutes: where the Agent is, with whom he is working, what activity he is carrying out, number of persons that he is in contact with, di stance of the agencies, and general observations. The academic levels, training in extension and experience of the directive personnel of the Extension Service, are higher than that of the Agricultural Agents. The agents use a higher percentage of their time in the office and less time in the f arms and homes of the farmers. The time consumed in non-educational activities (64%) is much higher in relation to time spent in educational activities (36%). Seventy-two percent of the persons interviewed consider that the agents do not make efficient use of their time. The major part of the persons interviewed consider that the establishment of a pattern for use of time, training courses in extension, supervision visits, transportation and adequate communication are factors which will help the agents to make better and more effective use of their time.
