Acoustic Flowmeter Prototype Evaluation Tests

Description: Summary: "Prototype tests of an acoustic flowmeter system were made in a 24-ftdiam power penstock at Oahe Dam to evaluate the system prior to permanent installation in the outlet works at Summersville Dam. Comparative discharge measurements included acoustic, penstock pressure-momentum (Gibson), turbine model test ratings, scroll-case pressure differential (Winter-Kennedy flowmeter), and surge tank volume changes. The acoustic flowmeter measurements were very consistent and many of the comparisons were within 1%. The location of the measuring section for a single-path acoustic flowmeter must be selected to give a known or measurable relation between the flow pattern of the whole section and that along the acoustic path" (p. xi).

Adjusting Corn Belt Farming to Meet Corn-Borer Conditions

Description: "The European corn borer is recognized as a dangerous enemy of the corn crop.... Its eradication is considered economically impossible but it is believed that the injury may be kept at a point so low that little commercial damage will occur during normal seasons. This can be done by using control measures and practices that have proved to be effective.... On some farms some changes in the crops grown and in their sequence will aid materially in controlling the borer and may prove profitable even when borers are not present. The control program for the individual farm should be given consideration at once in order to avoid sudden disturbance of the organization and operation of the farm when control measures do become inevitable. The necessity of concerted effort by all producers in an infested district becomes evident when the life habits of the borer are considered." -- p. ii

Advice to Forest Planters in the Plains Regions

Description: "Advice about tree planting to provide a windbreak and a supply of firewood, fence posts, and wood for repairs should be especially valuable to the settler in the Plains region. This bulletin gives advice that will enable him to select the species of trees that will bring the most profitable returns without overburdening him with care. Following the description of each species of tree adapted to the region, the points to be avoided in connection with its planting are summarized in a few concise 'dont's.' Information and advice also are given regarding time for planting, methods of cultivation, pruning, etc." -- p. 2
