The Burnett Control Gate For Irrigation Channels, B Swan

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

THIS type of check-gate for use in irrigation ditches, was evolved on the Kimberley Research Station and has definite advantages over wooden or concrete structures in that it is termite-proof and can be removed and replaced in a few minutes to permit of the channel being cleaned out by straight runs with modern machinery.

Making Your Own Beehives, R S. Coleman

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

THE publication of this article runs counter to my own principles to some extent as I have long maintained that most beekeepers will find it cheaper in the long run to purchase factory-made hives and frames.

I realise, however, that many apiarists possess both the skill and equipment to make hive-bodies, and that some at least can occupy slack periods profitably in this manner.

Hold On To Your Egg Profits, J A. Hoy

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

IN recent years, much sound advice has been made available to poultry farmers to assist them in developing their properties and operating them on profitable lines.

Much of this advice has been utilised to good advantage, but there are still many properties on which the profits are being reduced by feed wastage, damage by rats and mice, lack of sufficient attention to egg quality, unnecessarily high labour costs and failure to keep farm records.

Irrigation In Western Australia : Report On Government-Controlled Areas : 1958-59, H K. Gibsone

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

IRRIGATION in the south-western portion of Western Australia is mainly confined to the coastal plain west of the Darling Range where the three main irrigation districts of Harvey, Collie and Waroona have been established by the State Government.

The Government-controlled irrigation areas extend southward from Waroona (70 miles from Perth) to Dardanup (120 miles from Perth) and have an average width of about five miles.

Bulk Handling Of Superphosphate, H G. Cariss

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

A MAJOR factor in our agricultural production is the outlay for fertilisers, including the cost of their application to the land.

Any means which can be employed to reduce these costs are therefore of extreme importance to the State's agriculture.

The bulk-handling of fertilisers could be one way of reducing these costs to the farmer.

Australian Spark Arrester Tests, W. F. Baillie, G. H. Vasey

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

FORMAL tests on spark arresters are conducted by The Tractor Testing Committee at the Testing Station, Werribe, on behalf of those Companies concerned with tractors, engines or spark arresters who wish to have these equipments tested.

The arrester is tested on the engine it is specially designed for (as in this instance), or if it is sold for use on any or several engines, it is tested on an engine of the highest power for which the spark arrester is intended.

Australian Spark Arrester Tests : Spark Arrester For Fordson Dexta, W. F. Baillie, G. H. Vasey

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

FORMAL tests on spark arresters are conducted by The Tractor Testing Committee at the Testing Station, Werribee, on behalf of those Companies concerned with tractors, engines or spark arresters who wish to have these equipments tested.

The arrester is tested on the engine for which it is especially designed or if this is not convenient, it is tested on an engine having the characteristics and power for which the spark arrester is intended.

Australian Tractor Tests : No. 31, 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. 31 of this test; test 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. Graphs of belt test performance, shown in the Technical Report, are not shown here.
