From introduction: This report embodies the results of investigations of three gold mining districts in Josephine and Curry Counties, southwestern Oregon.

From abstract: This report presents the results of a reconnaissance of most of the mining districts of Oregon east of the Cascade Range, with the exception of the districts in the Sumpter quadrangle. The districts described are distributed through an area roughly coincident with the Blue Mountains, which extend over much of the northeast quarter of the State.

From Abstract: Two areas and their included mineral deposits, situated in Josephine County, southwestern Oregon, are described in this report. They lie within the Klamath Mountains, a region which is made up for the most part of rugged ridges trending in various directions but which, when viewed from higher summits, resembles a dissected plateau and is known as the Klamath peneplain. Rocks of both igneous and sedimentary origin are abundant in the districts described. The marine sedimentary rocks of the areas comprise a thick series of Carboniferous strata, with some interbedded volcanic rocks, and portions of the Galice formation, of Jurassic age, and of an Upper Cretaceous formation. The rocks of fluviatile origin include Tertiary conglomerate, Pleistocene valley fill, termed the " Llano de Oro formation," and somewhat later Pleistocene gravel and alluvium, in part glacial debris. Recent gravel is found along the present streams. The igneous rocks include several varieties of greenstone of probable Paleozoic and Mesozoic age and serpentine of late Jurassic or early Cretaceous age.

Revised edition. "This bulletin applies both to the western portions of the United States in which ordinary farm crops are grown largely under irrigation and to western Oregon and Washington where irrigation is not essential for strawberry production but may be profitable. It describes methods practiced in the more important commercial strawberry-growing districts of the West; it aims to aid those persons 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 of irrigating other crops. Details must necessarily be governed largely by the character of the crop grown. Since strawberries in the humid areas frequently suffer from drought which causes heavy losses in the developing fruit, the information may prove suggestive to many growers in those areas who could install irrigation systems at small expense. This bulletin gives information on soils and their preparation, different training systems, propagation, planting, culture, the leading varieties, harvesting, shipping, and utilization." -- p. ii
