    Description / Table of Contents: Zusammenfassung Zwei Kartoffelsorten,Redskin undMajestic, wurden unter vier verschiedenen Bewässerungsverfahren kultiviert: 1. Keine Bewässerung. 2. Bewässerung vor der Knollenbildung; 3. Bewässerung nach der Knollenbildung; 4. Bewässerung während der Wachstumsperiode der Pflanzen. Beide Sorten erlitten den gr\:ossten Schaden durch die NacktschneekenMilax budapestensis(Hazay) undArion hortensis F\'er, wenn die Pflanzen bew\:assert wurden (Tabelle 1). Die Knollen der SorteRedskin waren st\:arker besch\:adigt als jene der SorteMajestic (Tabelle 2). Eine gr\:ossere Anzahl vonRedskin-Knollen wiesen mehr als zwei L\:ocher auf. Die Zeit der Anpflanzung beeinflusste das Ausmass des Schadens bei keiner Sorte in grossem Masse (Tabelle 3). Es wird auf m\:ogliche Erkl\:arungen f\:ur diese Unterschiede hingewiesen. Der Ertrag an unbesch\:adigten Knollen wurde durch die Bew\:asserung erh\:oht, obwohl der Schaden durch die Nacktschnecken ebenfalls zunahm (Tabelle 4). In dieser Hinsicht hatteMajestic mehr Nutzen von der Bew\:asserung alsRedskin.
    Abstract: Résumé On a fait pousser deux variétés de Pomme de terre,Redskin etMajestic, dans quatre régimes différents d'alimentation en eau: 1. pas d'irrigation; 2. irrigation avant la formation des tubercules; 3. irrigation après la formation des tubercules; 4. irrigation pendant la période de croissance des plantes. Les limacesMilax budapestensis (Hazay) etArion hortensis Fér. causaient les plus grands dommages aux deux variétés quand les plantes étaient irriguées (Tableau 1). La variétéRedskin était plus sévèrement endommagée queMajestic (Tableau 2). Les tuberculesRedskin avaient la plus grande proportion de tubercules avec plus de deux cavités. Le moment de la plantation était sans importance pour les deux variétés (Tableau 3). L'auteur avance des explications à ropos dep ces différences. L'irrigation augmente la production de tubercules non endommagés même quand elle augmente les dégâts de limaces (Tableau 4). Sousce rapport la variétéMajestic plus que la variétéRedskin profitait de l'irrigation.
    Notes: Summary Two varieties of potato,Redskin andMajestic, were grown with four water regimes;-unirrigated, irrigated before tuber formation, irrigated after tuber formation, and irrigated throughout the growing season. The damage done by slugs and the yields were measured. Both varieties suffered most damage from slugs when irrigated after the tubers started to form. MoreRedskin tubers were damaged thanMajestic and a greater proportion had more than two holes. Possible explanation for these differences are suggested. Yields of undamaged tubers were increased by irrigation even though damage by slugs increased. In this respectMajestic benefitted more thanRedskin from irrigation.

    Notes: Abstract An experimental study of the propagation of flexural waves in an elastic beam of circular cross section subjected to an approximate-step-function bending moment is given. The test beam was a low-carbon-steel bar 2 in. diam × 30-ft long and was suspended in a vertical position by a pin located near the upper end. The step moment was applied at the upper pinned end of the bar by an arrangement of two high-pressure, nitrogen-operated cylinders. The strains were measured with strain gages located at eight stations along the bar. The experimental results are compared with results obtained from a solution of the “Timoshenko” beam by W. Flügge and E. E. Zajac for a semi-infinite pinned-end beam subjected to a suddenly applied bending moment at the pinned end. The experimental results are correlated with the predictions of the theoretical solution.

    Notes: Abstract A reflex camera that incorporates a light source and spectroscope for recording in-plane displacement fringes formed by reflective diffraction gratings is described and illustrated. A technique for replicating reflective diffraction gratings on plane metallic surfaces is given in detail. Typical fringe patterns of a mild-steel tension specimen containing a long shallow notch obtained using 6000-lines/inch gratings show the elastic deformation of the specimen. The method should prove a useful supplement or alternative to reflective photoelasticity in elasto-plastic studies, particularly when strain distributions in the transition region are of interest.
