Set Stocking Has A Place In Soil Conservation Farming, J E. Watson
Journal of the Department of Agriculture, Western Australia, Series 4
Set stocking of sheep at increased stocking rates is rapidly becoming popular with farmers in the agricultural areas of Western Australia.
But will set stocking increase soil erosion hazards? It should do just the reverse, according to Soil Conservation Adviser J. E. Watson, B.Sc, who claims that set stocking has a place in soil conservation farming.

The Development Of Irrigation In Nebraska, 1854–1910: A Descriptive Survey, Martin Evald Carlson
The Development Of Irrigation In Nebraska, 1854–1910: A Descriptive Survey, Martin Evald Carlson
Department of History: Dissertations, Theses, and Student Research
Preface (excerpted)
The primary purpose of this study is tto trace the development of irrigation in Nebraska from the organization of the state as a territory in 1854 through the rest of the nineteenth century. This period covers the first four stages through which irrigation progressed: individualistic, corporate, district, and state. A brief discussion of the North Platte Project is included, however, in order to carry the story into the fifth and final stage--the development of irrigation with Federal aid, as provided for in the Reclamation Act of 1902.
The emphasis of this work is on the irrigation movement and …

Fisheries Report Ii (2) - Preliminary Report On The Effectiveness Of Escape-Gaps In Crayfish-Pots, B. K. Bowen
Fisheries Report Ii (2) - Preliminary Report On The Effectiveness Of Escape-Gaps In Crayfish-Pots, B. K. Bowen
Fisheries Research Reports
The Western Australian commercial crayfish, Panulinrus cy,nus George, (1962)", is caught in depths ranging from a few feet to approximately 45 fathoms. In the shallow waters large numbers of crayfish measuring, less than the legal minimum length are brought to the surface in the standard commercial crayfish pots. The law requires that these undersize crayfish be returned to the sea, but there is always the temptation to retain them for illegal sale. In addition, the undersize crayfish which are returned to the sea are often damaged by handling. The probability is that their mortality rate is higher than those which …

Swing Fence Flood Crossing For Creeks In The Kimberleys, A L. Payne
Swing Fence Flood Crossing For Creeks In The Kimberleys, A L. Payne
Journal of the Department of Agriculture, Western Australia, Series 4
FENCING is the basis of the regeneration programme on the eroded Ord River catchment area, and the fences constructed must cross numerous creeks.
But heavy downpours of short duration characterise the wet season experienced in this area.
Because the rain falls on to bare, compacted ground, run-off is intense and gullies and creeks rise rapidly, causing serious damage to conventional fences and flood gates across watercourses.

Bulletin of the University of Nebraska State Museum (1924–2023)
Although primarily a systematic study, variations in the integumental striae and chaetotaxy of the legs are discussed. The genus Octobdellodes Atyeo, 1960 is synonymized with Bdellodes Oudemans, 1937 and the sugenus Cytobdella Mihelcic, 1958 is synonymized with Cyta von Heyden, 1826. The genus Bdellodes is divided into the subgenera Bdellodes and Hoploscirus Thor, 1937 (=Thoribdella Grandjean, 1938, new synonymy). Twenty-two species are now known to occur in New Zealand and the outlying islands. These include four known species: Bdella iconica, Bdellodes (Roploscirus) lapidaria, B. (R.) reticulata, and Cyta latirostris, and eighteen new species: Bdellodes (Bdellodes) harpax, B. (B.) oraria, …

Hints On Irrigating Citrus With Saline Water, Stanley Thomas Smith
Journal of the Department of Agriculture, Western Australia, Series 4
IN the past few years a number of citrus orchards near Perth have shown signs of damage caused by excess "salt" (chloride) uptake. All have been irrigated either from the Canning River or from private bores or dams.
Senior Soil Research Officer S. T. Smith describes glasshouse experiments which have given some useful guides to minimising "salt" damage in citrus trees irrigated with low-quality water.

Journal of the Department of Agriculture, Western Australia, Series 4
THE term f.a.q. refers to "fair average quality" as a standard for the sale of wheat -*- produced in Western Australia during any particular season.
The practice of using this standard developed after a standard sample of wheat grown in 1904 was obtained and declared to have a bushel weight of 62 lb.
A Progress Report On Commercial Cotton Growing On The Ord River Project, William John Toms
A Progress Report On Commercial Cotton Growing On The Ord River Project, William John Toms
Journal of the Department of Agriculture, Western Australia, Series 4
The recommendations given in this article have been built up from the experience of the author in growing 200 acres of cotton in the Ord River area during the 1962-63 season for the Department of Agriculture, from findings made by Kimberley Research Station, and from discussions with the present farmers in the area.
When a new form of agriculture is introduced into a new area techniques and ideas change rapidly as farmers become acquainted with their new environment and the new crops. The recommendations will therefore require constant revision.

The Archeology Of The Lime Creek Site In Southwestern Nebraska, E. Mott Davis
The Archeology Of The Lime Creek Site In Southwestern Nebraska, E. Mott Davis
University of Nebraska State Museum: Staff and Affiliates, Publications
The Lime Creek site is a stratified Early Lithic (Paleo-Indian) camp site buried in the Terrace-2A alluvial fill of a valley in the dissected loess plains. Geological correlations indicate an early Valders (Wisconsin- IV) date. A radiocarbon date (No. C-471) of 9524 B.P. from just below Lime Creek I, the lowest occupation zone, must be taken only as a minimal possible age for the site. The animal bones in Lime Creek I are primarily of pronghorn and beaver, whereas those in Lime Creek III, the highest occupation zone, are exclusively of bison. The change in hunting patterns seems due to …

Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd
Interbasin Movement Of Ground Water At The Nevada Test Site, Isaac J. Winograd
Publications (WR)
The present paper presents hydraulic evidence for the interbasin circulation of ground water through carbonate rocks of Paleozoic age at the Nevada Test Site. An integral part of this evidence is the discovery that aquifers in alluvium and tuff, formerly thought to be the principal aquifers at the Test Site, are semiperched above a thick tuffaceous aquiclude that separates them from the carbonate rocks.
This paper is based on one of the studies being made by the Geological
/="/">Survey for the Atomic Energy Commission. These studies seek to evaluate
