Strawberry Culture: Western United States (open access)

Strawberry Culture: Western United States

"This bulletin applies to that part of the United States in which ordinary farm crops are grown largely under irrigation. It describes methods practiced in the more important commercial strawberry-growing districts in the irrigated regions of the West; it aims to aid those familiar only with local and perhaps unsatisfactory methods, as well as inexperienced prospective growers. The fundamental principles of the irrigation of strawberries are substantially the same as those which apply in the growing of other crops. Details of operation must necessarily be governed largely by the character of the crop grown. Since strawberries in the humid regions frequently suffer from drought, which causes heavy losses in the developing fruit, the information may prove suggestive to many growers in those localities who could install an irrigation system at small expense. Detailed information is also given as to soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, and shipping. Methods of using surplus strawberries for preserves and jams, for canning, and for flavoring for various purposes are given." -- p. 3

Dry Farming for Better Wheat Yields: The Columbia and Snake River Basins (open access)

Dry Farming for Better Wheat Yields: The Columbia and Snake River Basins

"This bulletin deals in particular with the dry farming methods practiced on grain farms in the Pacific Northwest where the rainfall is less than 18 to 20 inches annually, but it also contains advice helpful to all farmers of that region who practice summer-fallowing. Its purpose is to show the possibility of increasing crop yields in the dry-farming areas by using improved methods, and to discuss the practices which have been found most advantageous.... The purposes of summer-fallowing and details of the methods of their accomplishment are presented, with the application of these methods to the cultivation of "blow" soils and "nonblow" soils, and methods are suggested for preventing and stopping the blowing of soils. Attention is given to the seeding of winter and of spring wheat, and suggestions are made for properly maintaining the organic matter in the soil." -- p. 2

Recovery of Zinc from Low-Grade and Complex Ores (open access)

Recovery of Zinc from Low-Grade and Complex Ores

From Introduction: "Vocalization in retorts has been, until recently, the only commercial process of producing spelter, hence the zinc mine operators have had to meet the terms of the zinc mine operators have had to meet the terms of the zinc smelters in regard to the following requirements: (1) Minimum percentage of zinc the ore must contain; (2) the chemical combination of the zinc in the ore; (3) the proportion present of those elements that interfere with the successful recovery of the zinc when the ore is retorted. As stated previously, and as will be shown later, a large part of the valuable mineral content of the ore is lost in effecting this concentration. As a result of the other requirements that have to be met in zinc smelting, much zinc is lost in the mining and milling of zinc ore."
