Avian Botulism Information On Earlier Research

United States Fish and Wildlife Service: Publications

Over the years, the disease, avian botulism, has been an important factor limiting populations of waterfowl, particularly in the West. Great numbers (doubtless millions) of ducks have died from this disease, and because of such heavy tolls, studies of the malady were begun early in the century and continued intermittently to the present time.

This summary brings up to 1950 the series of investigations on botulism by Wetmore (1918), Kalmbach (1930, 1932), Kalmbach and Gunderson (1934), Sperry (1947), and others. This information has been compiled as a service to those concerned with conservation of our waterfowl resources. A cooperative agreement …

Trees Of Western Australia— Coral-Flowered Gum, C A. Gardner

Journal of the Department of Agriculture, Western Australia, Series 3

Among the more decorative small trees available for planting in the Eastern Agricultural Areas, there are few more suitable that Eucalyptus torquata. This tree, known also as the "Christmas Tree" of the Coolgardie and Dundas districts usually blooms during December, and its handsome drooping coral-pink blossoms make it a conspicuous object in the woodlands at that season of the year. It was first discovered by L. C. Webster near Coolgardie in 1901, on a stretch of stony dioritic country 25 miles in length and about a quarter of a mile in breadth. It is found at least as far south …

Trees Of Western Australia— White Mallee, C A. Gardner

Journal of the Department of Agriculture, Western Australia, Series 3

This species is usually found in mallee form, growing from 10 to 18 feet tall, but may at times possess a single stem, and is thus a small tree. Both mallee and tree forms have characteristically a broad 'base or stock, so that frequently in the mallee forms the individual stems arise well above the soil level from a large domelike base. As a tree the stem may be as much as 18 inches in diameter. The species is characterised in the field by its white or pink bark which is covered throughout externally with a white smooth talc-like powder. …

The Glorious Gladiolus, F Jackson

Journal of the Department of Agriculture, Western Australia, Series 3

Possessing a wide colour range and striking beauty of form, the gladiolus is one of our most popular and spectacular annuals. When grown in large numbers, the mass formations of varied hues make beds of gladioli a sight to be remembered, but the flower is probably displayed at its best when used as a home decoration.

Thin-Shelled Eggs, R H. Morris

Journal of the Department of Agriculture, Western Australia, Series 3

Thin-shelled eggs are responsible for a loss of thousands of pounds annually to the West Australian poultry industry. To a very large extent the flock owner can control the percentage of thin-shelled eggs laid by his flock and this article outlines how this control can be exercised.

Scald In Granny Smith Apples, F Melville, S E. Hardisty

Journal of the Department of Agriculture, Western Australia, Series 3

The Granny Smith has been the most widely grown variety of apple in Western Australia for many years. In 1946 a survey showed that more than one-third of the apple trees growing in this State were Granny Smiths and new plantings and reworkings since then have been predominately of this variety. Production in 1947, a very heavy crop year, exceeded a million bushels, which represented about 40 per cent, of the total apple crop for that year. This decided preference shown by growers for the Granny Smith emanates from its suitability to West Australian conditions and the strong demand for …

Canonical Field Theory -- A Prototype Example, Bruce Knight

Knight Laboratory

The equations of a field may be put into a standard "Lagrangian" form from which several conservation laws follow directly. As an illustrative example, a string free to vibrate in two directions is investigated; this example clearly illustrates the outstanding features of the canonical theory, while avoiding the notational and physical complications encountered in most systems of practical interest. The conservation laws are interpreted for the string. The theory is further developed to express the field's behavior in terms of canonical coordinates and momenta. Quantum conditions are introduced, as in meson theory and quantum electrodynamics. It is shown that the …

Influence Of Certain Soil-Proftle Characteristics Upon The Distribution Of Roots Of Grasses, R. L. Fox, J. E. Weaver, R. C. Lipps

Papers of John E. Weaver (1884–1956)

A method has been devised by Weaver and his coworkers (15) by which a root system may be sampled from the soil surface to a depth of maximum root penetration. The root system may then be separated from the soil without vertical displacement, photographed, and compared with soil profile characteristics. In the present investigation an attempt has been made to relate some chemical and physical properties of the soil to root distribution.

Beekeepers' Field Day

Journal of the Department of Agriculture, Western Australia, Series 3

About 80 beekeepers, attended the first apicultural field day organised by the Department of Agriculture in conjunction with the Beekeepers' Section of the Farmers' Union of Western Australia. The field day was held at the Government Apiary, Yanchep, on December 13, and hot, sunny weather made it a successful and interesting innovation.

Nitrogen-Fixing Bacteria For The Inoculation Of Leguminous Seeds

Journal of the Department of Agriculture, Western Australia, Series 3

The Plant Pathology Branch of the Department of Agriculture can supply the cultures listed below. Owing to the time taken to prepare the cultures, however, and owing also to the fact that in the busy time of the year there is frequently a tremendous accumulation of orders, farmers are requested to lodge their applications together with the requisite payment at least a fortnight before they wish the culture to be forwarded.

TICK FEVER

" I am experiencing trouble with young pullets losing the use of their legs, with accompanying form of diarrhoea. Most of the affected birds have dark coloured combs and die within two days of showing the first symptoms of being diseased. I have searched for tick but am unable to locate any trace of them. Can you assist me in this matter?"

The Citrus White Fly, C F.H Jenkins, D G. Shedley

Journal of the Department of Agriculture, Western Australia, Series 3

For the first time in Western Australia the citrus white fly was recorded on lemon trees at Maddington in 1950 and since then it has been found to be widely distributed in the Maddington-Gosnells area and in scattered situations in the Darling Range, Middle Swan and Perth suburbs. It is also of interest to note that the insect appeared in Mildura citrus orchards in Victoria (Anon 1952), about the same time as it was reported from Western Australia, although there appears to be no explanation for its sudden dispersal over the continent.

The Testing Of Bacterial Strains Used In The Inoculation Of Legumes, Olga M. Goss

Journal of the Department of Agriculture, Western Australia, Series 3

A part from their value as fodder plants, legumes such as peas, beans, clovers, vetches and lucerne play an important role in increasing soil fertility. Their value in the soil-enriching sphere has been recognised for centuries, but it is only comparatively recently that the reason for it has been fully understood.

Growth And Respiratory Studies Of Saccaromyces Cerevisiae In The Presence Of Selenium, Robert M. Pengra

Electronic Theses and Dissertations

The occurrence of selenium in certain soils of the United States and its detrimental effect upon livestock pastured on or fed forage from these areas has been well established. Selenium poisoning will not be reviewed here as several excellent reviews have been published (1, 2, 3). Studies on the metabolism of selenium by Sac-charomyces cerevisiae have been reported by Potter and Elvehjem (4), Lardy and Moxon (5), and Fels and Cheldelin (6, 7, 8). An attempt has been made in this thesis to repeat and enlarge on some of these studies. While this investigation may contribute information on the selenium …

Geology Of The Oak Cliff Quadrangle, Dallas County, Texas, Wilson Bryan

Field and Laboratory

Consolidated marine rocks of the Oak Cliff Quadrangle belong to a portion of the Upper Cretaceous Austin formation. On the basis of lithology the formation is divided into a lower chalk and a middle marl. Buried channels, some 6 feet deep and 95 feet across, occur in the lower chalk. They result from submarine scouring, indicating that deposition was not a continuous process. Bentonite seams, some as much as 6 inches thick, occur at various horizons in the lower chalk, pointing to periodic volcanic activity. Numerous small normal faults in the Austin formation may have resulted from differential compaction of …
