Bulletin No. 114 - The Movement Of Nitric Nitrogen In Soil And Its Relation To "Nitrogen Fixation", Robert Stewart, J. E. Greaves

UAES Bulletins

In the spring of 1903, we commenced at the Utah Experiment Station a series of experiments, the purpose of which was to study the development and movement of nitrates in irrigated soil. The work was so outlined that it should give some very definite results, both as to the influence of water and the plant, upon the nitric nitrogen content of the soil.

Most of the species described in this paper were received for determination through the Bureau of Entomology, United States Department of Agriculture, and are of economic importance. The figures made to illustrate certain details were all drawn with the aid of the camera lucida. Comparative measurements were made with an eye-piece micrometer used in the Zeiss binocular microscope.

New Hymenoptera From The Phillipine Islands, J. C. Crawford

Co

The species described in this paper were for the most part collected by the Rev. Robert E. Brown, S. J., although a few are from the material gathered by the Rev. William A. Stanton, S. J. Under each species credit has been given to the collector. In the Philippine Journal of Science a Father Brown has given a list of the species of Hymenoptera found in the islands and has cited several names sent him by the late Dr. W. H. Ashmead which are manuscript names. In describing these species, of which no manuscript has been found, the name used …

Bulletin No. 106 - A Study Of The Production And Movement Of Nitric Nitrogen In An Irrigated Soil, Robert Stewart, J. E. Greaves

UAES Bulletins

The problem of maintaining the nitrogen content in our agricultural soils is one of vital importance to the development of a permanent system of agriculture. Any investigation, therefore, which tends to throw any light on the conditions which are necessary for maintaining the maximum supply of nitrogen in our soils needs no apology for its institution.

Practical Information On The Scolytid Beetles On North American Forests I. Barkbeetles Of The Genus Dendroctonus, Andrew Delmar Hopkins

The Bark Beetles, Fuels, and Fire Bibliography

During the writer's investigations of extensive insect depredations in the forests of West Virginia, from 1890 to 1902, he was forcibly impressed with the importance of the forest-insect problem in connection with any future efforts toward the successful management of the forests of this country, and was thus led to give special attention to the subject. It was soon realized that among the principal groups of insect enemies of forest trees the scolytid bark and wood boring beetles must occupy first rank, both in economic importance and systematic interest. Subsequent investigations in West Virginia, in connection with the work of …

Monographie Des Vespides De Genre Nectarina, R. Buysson

Bu

Les Nectarina ou Nectarines sont des Vespides vivant en sociétés très nombreuses et pérennes. Leur industrie est grande et leur nidification des plus remarquables. Elles habitent uniquement les contrér,s chaudes et tempérées de l'Amérique. On les trouve répandues depuis ie Mexique jusque dans la Bépublique Argentine. Elles ont été signalées depuis fort longtemps, parce qu'elles emmagasinent du miel dans les alvéoles de leurs nids, particularité bien connue des voyageurs, qui la tinrent d'abord des Indiens.
