Water Vapor Measurements Using Infrared Absorption, Duard S. Woffinden
Water Vapor Measurements Using Infrared Absorption, Duard S. Woffinden
Reports
Man’s attempt to control the amount of available water has taken two approaches, i.e., weather modification and water storage through the use of man-made reservoirs. In either case, it is necessary to ascertain the water vapor content of the atmosphere. In the case of weather modification, if the water vapor content is insufficient, it is futile to attempt to start precipitation. In the case of reservoirs, it is important to know the evaporation rate since it has been demonstrated that some reservoirs provide a net negative contribution to the total water supply by increasing the normal evaporation losses. Any attempt …

Lot Feeding Of Beef Cattle. 3. Facilities Required For A Feed Lot, W J O Wilkie
Journal of the Department of Agriculture, Western Australia, Series 4
MANY THINGS must be considered in planning a feed lot.
The site must be well chosen, fencing, gates and yards must be adequate for the cattle carried and feeding and watering facilities should be of a high standard.
Other things to consider are the provision of shelter and shade for the cattle and buildings for feed storage and other purposes.

Rabbit Control, Warren V. Johnson
Vertebrate Pest Conference Proceedings: 2nd (1964)
Common California rabbits comprise two major genera. One, the genus Sylvilagus, or true rabbit, is represented by the cottontail and brush rabbits. The second of the two major genera is the genus Lepus, or hares. These are erroneously called the jack rabbits and snow shoe rabbits. The common jack rabbit, Lepus californicus, is the most familiar one throughout California and portions of some of the other western states. Because of their size and abundance, they are by far the most destructive - so emphasis will be placed on this species throughout the balance of this report. The diet of the …
Animal Control In New Zealand, Walter E. Howard
Animal Control In New Zealand, Walter E. Howard
Vertebrate Pest Conference Proceedings: 2nd (1964)
New Zealand has a multiplicity of challenging animal-control problems, and all of them concern animals which man has intentionally introduced either for sport, food or fur. Since the beginning of European settlement in the 19th Century, approximately 53 species of mammals and 125 species of birds have been deliberately or accidentally introduced into New Zealand, and 34 birds and 31 mammals have become established (Wodzicki, 1950). The principal reasons the exotic big game animals (Riney, 1955), fur bearers and feral domestic livestock have been so destructive to certain habitats in New Zealand are because 1) some of the soils are …
Starlings In The Pacific Northwest, H. Nelson Elliott
Starlings In The Pacific Northwest, H. Nelson Elliott
Vertebrate Pest Conference Proceedings: 2nd (1964)
As is the case in many sections of the country today, starlings are causing increasing concern in the Pacific Northwest. When these birds were first recognized in Washington, Oregon and Idaho in the early 1940's only small numbers were seen, usually with blackbirds. During the 50's, however, the number of wintering starlings increased from a few birds, to thousands, with estimated flocks of 25,000 to 50,000 in western Oregon and along the Snake River Valley in Idaho and eastern Oregon. During the past five years winter resident populations in these areas have been estimated by the 100,000's, with some observers …

The Role Of Industry In Developing New Materials For Vertebrate Pest Control, G. Hermann, W. M. Zeck
Vertebrate Pest Conference Proceedings: 2nd (1964)
In the first paper presented to you today by Dr. Spencer, an expert in the Animal Biology field and an official authority at the same time, you heard about the requirements imposed on a chemical in order to pass the different official hurdles before it ever will be accepted as a proven tool in wildlife management. Many characteristics have to be known and highly sophisticated tests have to be run. In many instances the governmental agency maintains its own screening, testing or analytical programs according to standard procedures. It would be impossible, however, for economic and time reasons to work …

Soil Erosion By Water In W.A. Cropland : A Serious And Widespread Problem, Department Of Agriculture, Western Australia
Journal of the Department of Agriculture, Western Australia, Series 4
Much wheatbelt agriculture is based on thin topsoils which are inherently infertile by world standards. Erosion even to the depth of cultivation will cause the loss of:—
• most of the original topsoil
• the phosphate build up from years of "super" applications
• any accumulation of organic matter and humus.
