- Strawberry Culture: Western United States
- Revised edition. "Strawberries can be grown in those parts of the western Untied States in which ordinary farm crops are irrigated as well as in western Oregon and Washington, where irrigation is not essential but may be profitable. The principles of irrigating strawberries are essentially the same as those for other crops. Because strawberries are sensitive to the alkali salts that irrigation brings to the surface, such salts must be washed out or skimmed off. The strawberry grower, after choosing a suitable site and preparing the soil carefully, should select varieties adapted to his district and needs. He should use plants that are disease-free. In California, southern Arizona, New Mexico, and Texas the plants should have undergone a rest period. Usually the growers plant during the period of greatest rainfall. By using the recommended systems of training and care before, during, and after setting of the plants and the suggested methods of decreasing diseases and insect pests, he should obtain better yields. A grower can furnish consumers a better product by using good methods of harvesting and shipment. He can prolong the fresh-fruit season only a little by the use of cold storage, but he can extend his market by growing varieties suitable for preserving, canning, and freezing." -- p. ii

- [Plates I-X]
- Illustrations accompanying a report investigating the locations of vanadium-bearing phosphatic shale in West-Central Wyoming and Southeastern Idaho. The set includes seven maps (Plates I and V-X) showing the location of rock formations in the area and three charts (Plates II-IV) showing the correlation between the occurrence of vanadium deposits and the thin persistent beds of phosphate rock, oolite, siltstone, dolomite, and limestone with which they are interbedded.

- Strawberry Culture: Western United States
- 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. Because strawberries in the humid areas frequently suffer from drought, which causes heavy losses in the developing fruit, the information may prove helpful 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
- Tungsten Resources of the Blue Wing District, Lemhi County Idaho
- From abstract: The Blue Wing district, Lemhi County, Idaho, is not only the principal tungsten mining district in the State but it has recently become one of the leading producers of tungsten in the United States.
