"The wheat jointworm is a very small grub which lives in stems of wheat, feeding on the juices of the plant and causing a slight swelling or distortion of the stem above the joint. The egg from which it hatches is laid in the stem by an insect resembling a small black ant with wings. This insect attacks wheat only. The injury which it causes to wheat is very distinct from that caused by the Hessian fly, yet the effects caused by these two insects are often confused by farmers." -- p. 1-2. This bulletin gives a brief outline of the life cycle and the nature of the injury to the plant by the jointworm so that any farmer may readily recognize its work and be able to apply the measures of control herein recommended.</p>Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910: Part 1. -- Analyses2010-02-21T23:09:24-06:00https://digital.library.unt.edu/ark:/67531/metadc12238/<p><a href="https://digital.library.unt.edu/ark:/67531/metadc12238/"><img alt="Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910: Part 1. -- Analyses" title="Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910: Part 1. -- Analyses" src="https://digital.library.unt.edu/ark:/67531/metadc12238/small/"/></a></p><p>From Significance and value of Analyses of Coal: "The analyses published in this report cover samples of coal collected in many different parts of the country with unusual care by experiences men, in such manner as to make them representative of extensive beds of coal."</p>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.

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."</p>
