Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples

From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."

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

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 …

Rhodes Grass (open access)

Rhodes Grass

"Rhodes grass was introduced from southern Africa in 1902, and has proved of value for cultivation in the warmer parts of the United States, being grown more largely in Florida and Texas than elsewhere.... It makes a heavy yield of hay of excellent quality, as the stems are slender, tender, and very leafy. The hay is cured easily and is relished by all kinds of live stock.... This bulletin mentions the soil preferences of this grass and gives the methods of seeding and after-treatment employed as well as handling the hay and pasturing and seed saving." -- p. 2

"The information given in this bulletin should enable farmers in the Great Plains and Western States to select from the more common species of grasses some one or more suited to their needs [for soil and water conservation]. Common harvesting equipment and farm machinery can be adapted to the proper handling of native grasses. This brings the cost of such work within the means of most farmers." -- p. i. Among the grasses discussed are wheatgrass, buffalo grass, bluestem, grama, Bermuda grass, wild rye, hilaria, Sudan grass, bluegrass, panic grasses, dropseed, and needlegrass.
