Several armed conflicts took place in Central America during the last 3 decades of the 20th century. In this commentary, we discuss (1) studies describing the interrelationships among health, violence, and poverty during and after these conflicts and (2) some important lessons learned from these studies. We hope that those lessons help epidemiologists and others who must confront, and describe, similar situations elsewhere.

The article describes the real customers of growers. The performance of growers is measured by how well their products are accepted by their consumers. The need for the industry to deliver the best-looking plants to retailers is emphasized. Factors and issues being considered by consumers include suitability to their lifestyle and good price.

Accumulated vegetative residue was a concern when Conservation Reserve Program (CRP) land returned to grain crop production. This study was conducted to determine the effect of residue management, tillage, and crop choice on grain yield in the first year of cropping on CRP land that was predominately smooth brome (Bromis inermisLeyss). Three residue management practices (undisturbed, shred, and remove), three tillage systems [moldboard plow, disk, and no till], and three crops {corn (Zea maysL.), soybean [Glycine max(L.) Merr.], and grain sorghum [Sorghum bicolor(L.) Moench]} were used in a factorial arrangement of a 3‐yr field experiment conducted in Nebraska on fine‐silty, mixed, mesic Udic Haplustoll; fine‐silty, mixed (calcareous), mesic Typic Ustorthent; and fine‐silty, mixed, mesic Cumolic Halustoll soils. Residue management was not significant for corn (P> F= 0.16), sorghum (P> F= 0.113), and soybean (P> F= 0.491) although there were significant residue × tillage interactions. Tillage system was not significant (P> F= 0.125) for soybean yields, but plowing significantly (P> F= 0.0001) increased both corn and sorghum yields. Mean corn yields were 13% less for the no‐till system than for the moldboard plow system. However, no‐till corn yield differences were not significant (P> F= 0.255) when plant population (a possible measure of planter performance) and percent green rating (a measure of weed control) were included as covariates. Our recommendation for the first year of grain crop production on smooth brome CRP land is to shred the residue and plant soybean in a no‐till system.

During the recent civil war in E1 Salvador, as in other modern wars, human rights abuses adversely affected health workers, patients, and medical facilities. The abuses themselves have been described in reports of human rights advocacy organisations but health sector adaptations to a hostile wartime environment have not. Agencies engaged in health work during the civil war adapted parties such as training of community based lay health workers, use of simple technology, concealment of patients and medical supplies, denunciation of human rights abuses, and multilevel negotiations in order to continue providing services. The Salvadorean experience may serve as a helpful case study for medical personnel working in wars elsewhere.

This article describes how William Russell, one of the early contributors to the elocutionary movement in this country, and at the time a prominent figure in the professional education movement, attempted to integrate his theories on education and elocution.

Many corn (Zea maysL.) experiments require total dry matter determination in addition to grain yield. Mechanized small‐plot grain harvest is a common practice, but determination of total dry matter is usually accomplished by hand harvesting. Hand harvesting is time consuming and labor intensive. Our objective was to construct a mechanized stover sampling system that would reduce the labor requirements for collecting dry matter data. A machine was assembled that cuts, chops, and delivers corn stover to a bag without hand cutting and carrying. A New Holland 707 forage harvester was modified and rear‐mounted on a Model 1910 Ford tractor to harvest a single row with a minimum width of 0.76 m. Chopped corn stover is blown through a tube over the top of the tractor to a platform on the front of the tractor where the material is collected and weighed. By using this machine, the number of people needed for data collection is reduced from eight to three, and longer rows can be harvested to increase experimental precision.

TO THE EDITOR. —I am presently preparing a paper on giant cell arteritis and read with interest an article by Stanley A. Uriu, MD, and Robert D. Reinecke, MD, in the November 1973 issue of the Archives titled "Temporal arteritis, steroid therapy, and pulmonary emboli" (90:355, 1973).These authors suggested that the treatment of this disease with high dose steroids may have a relationship to the pulmonary emboli supposedly verified in these cases. I cannot refute their theory, but I would like to suggest that these two patients may have had a vasculitis of the pulmonary arteries causing these symptoms, which are identical to pulmonary emboli seen in patients with systemic lupus erythematosus (SLE).I have recently observed such a case. I was initially quite confident with results of lung scans and clinical laboratory evidence that the patient indeed had multiple recurrent pulmonary emboli. She had been receiving anticoagulation therapy,
