Effect of the Reversal of Air Flow Upon the Discharge Coefficient of Durley Orifices
Note presenting an experiment to obtain information regarding the relationship between the coefficients for flow in the two directions through an inlet. The results indicate that the ratio of the orifice discharge coefficient from standard orifice to the discharge coefficient from reverse flow is always less than unity, but approaches unity with increasing ratio of box area to orifice area, and that even for a ratio of areas as low as twenty the ratios of the coefficients is not much less than unity.

Muscadine Grape Paste
Revised edition. "Muscadine grape paste is an economical, appetizing, and nutritious sugar-saving substitute for candy and other confections. It is excellent in combination with cheese, and especially with cottage cheese, as a substitute for the salad course or for a dessert. It may be made from the fresh fruit or preferably from the pulp of pomace left from grape juice and jelly making. It may be made with grape sirup or corn sirup instead of sugar. The pulp may be canned and the paste made at any convenient time or when desired for use. The making of muscadine grape paste is recommended for home use, but it may be made profitably for market where grapes are abundant. This bulletin gives directions for securing suitable fruit, the extraction of the pulp, and the sweetening, cooking, drying, and storing of the product, as well as the making of various combinations, fancy pastes, and pastes from other fruits." -- p. 2
