Farm Water Storage : Circular Brick Reservoirs, R P. Harington

Journal of the Department of Agriculture, Western Australia, Series 4

A circular brick tank is a cheap and efficient water storage which can be easily built on any farm. The method described below by Kimberley Research Station manager R. P. Harington was used to build a swimming pool—storage on the station.

Flooding And Salt Problems In The Wheatbelt, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

VALUABLE land has become salty in parts of the West Australian agricultural areas because most of the surrounding land has been cleared and developed for agriculture.

This salting of a small proportion of the land is part of the price paid for the development of agriculture in this State.

Drainage is not the answer to the wheatbelt flooding and salt land problems.

A more practical approach is to limit runoff from sloping land, and to make good use of salt-affected land by growing salt tolerant perennial pastures on it, says the Soils Division of the Department of Agriculture.

Irrigating Dry Season Crops In The Ord Valley : How To Prepare Land For Sowing, D F. Beech

Journal of the Department of Agriculture, Western Australia, Series 4

THE best way to grow dry season crops of safflower, linseed and rapeseed under irrigation in the Ord Valley is by sowing on to broad flat ridges, separated by small furrows 3 ft. 6 in. apart.

This system of sowing is called the "corrugation" method.

Orchard Planting Systems, K T. Whitely

Journal of the Department of Agriculture, Western Australia, Series 4

HAVING decided on the location of the orchard and the types of fruit trees to be planted, the grower is still faced with the problem of layout of the trees in the new orchard.

The Effects Of Tillage Implements On Cereal Yields, H M. Fisher

Journal of the Department of Agriculture, Western Australia, Series 4

Careful soil preparation is essential for cereal crops grown without fallow on clover ley land.

Crops give better yields where the land is broken up with a mouldboard or disc plough rather than a scarifier or similar machine.

The implements differ appreciably in their capacity to control weed growth and this is largely responsible for variations in cereal yields. "Takeall" disease is reduced by efficient weed control.

A Modified Copper Hot Water System, F J. Fielder

Journal of the Department of Agriculture, Western Australia, Series 4

A good supply of hot and boiling water for cleansing and sterilising utensils is essential for hygienic milk production.

Dairy Instructor F. Fielder, M.D.D., describes an efficient and economical modification of a copper hot water system for this purpose.

SINGLE copper units of 14 or 16 gallon capacity to supply hot and boiling water for the dairy are no longer good enough for most dairy farms.

Australian Tractor Tests : International A554d : Report On Test No. 36 (Farmers' Edition), G H. Vasey, W. F. Baillie

Journal of the Department of Agriculture, Western Australia, Series 4

THIS Report is taken from the full Technical Report No. 36; results are shown here in briefer form: fuller explanations are added.

Values quoted may be rounded out to two instead of three significant figures; to this extent the values may differ slightly but not significantly from those shown in the Technical Report.

Check Your Milking Machine, T Pavy

Journal of the Department of Agriculture, Western Australia, Series 4

MILKING machine efficiency testing carried out by officers of the Department of Agriculture's Dairying Division have shown that many machines are not up to standard.

One reason for this is that farmers do not check their machines regularly.

Water Cooling Towers : For Cooling Milk On The Dairy Farm, K Needham

Journal of the Department of Agriculture, Western Australia, Series 4

Experience on dairy farms where water cooling towers have been installed has shown that the quality and grading of milk and cream has been improved and maintained, particularly during the summer.

MOST defects in the quality of dairy produce can be attributed to the activity of micro-organisms which cause spoilage.

The Importance Of Rapid And Complete Milking, K Needham, W. G. Robinson

Journal of the Department of Agriculture, Western Australia, Series 4

COMPLETE withdrawal of milk from the udder as quickly as possible after the process of "let-down" has started, is an essential in good milking; management.

New Genera And Species Of Myripristid Fishes, In The Gulf Coast Cenozoic, Known From Otoliths (Pisces, Beryciformes)

School of Mines and Metallurgy Bulletins

Studies of fossil and Recent otoliths (sagittae) supply an important line of evidence, bearing on classification of teleost fishes, supplementary to that of anatomy, osteology, and "phylogenetic" paleoichthyology.

Squirrelfishes ( " Holocentridae" of authors) are generalized forms in which evolutionary divergence of some mag nitude is reflected in unpreservable details of anatomy, inconspicuous skeletal structures, and striking differentiation of the sagittae. Otoliths show the holocentroid complex to consist of one homogeneous unit (l\fyripristidae, elevated) and another more heterogeneous group (Holocentridae, restricted). These lineages have been separate. at least since the middle Eocene.

A revised classification, based on available lines of …

Local Control Of Crows By Trapping, C J. Woodbury

Journal of the Department of Agriculture, Western Australia, Series 4

THE common crow seen frequently around farms in the South-West is the raven (Corvus coronoides) whilst the pest of pastoral areas is the true Australian crow (Corvus cecilae).

Farmers and pastoralists, although recognising the importance of these birds as scavengers and destroyers of insects, particularly grasshoppers, sometimes for one reason or another, wish to reduce their numbers over a localised area.

Baiting with phosphorus has been used in the past, but the purpose of this article is to describe and illustrate a type of trap which has become universally known as the "Australian Crow Trap."

Water Conservation On The Farm, John W. Lewis

Journal of the Department of Agriculture, Western Australia, Series 4

SMALL scale conservation of water for agricultural use is becoming increasingly important throughout Australia.

As land development intensifies, it is natural that farmers turn to more dams and earthen tanks for stock water and irrigation.

Adequate water is essential to supply the carrying capacities made possible by improved pastures, and where greater quantities of water can be stored, fodder crops, pastures, orchards and vegetables can be irrigated.
