PARR 5 - CLOVER PARK “Faunists, as you observe, are too apt to acquiesce in

bare descriptions, and a few synonyms: the reason is plain; because all that may be done at home in a man’s study, but the investigation of the life and con- servation of animals, is a concern of much more trouble and difficulty, and is not to be attained but by the active and inquisitive, and by those who reside much in the country.”

The Natural History of Selbourne may seem a far cry from Clover Park, but the quotation is relevant to the enterprise which is in progress as part of PARR (Project of Applied Rural Research). On each of the field stations of Merck, Sharp and Dohme (Australia) Pty Ltd; Clover Park at Hamilton in Western Victoria, and Hillgrove Station at Armidale, New South Wales, portion of the station is used for experimental work, part is run as a commercial enterprise by a manager.

The experimental work has been fully described in a series of PARR publications, and in some papers from the veterinary officers concerned. (PARR 4 was re- viewed in Aust. v e f . J. 53 ( 3 ) :123). PARR 5* de- scribes the conduct of the commercial section of Clover Park where the manager, Mr J . Payne, has applied the findings from the experimental work on the control of the parasitic diseases of sheep and cattle to the com- mercial flock and herd. *Clover Park.

The managerial work is fully described and there is a full economic analysis. The booklet is beautifully illustrated in colour. Everyone concerned with animal production from pastures, agricultural economics, farm management and disease control will find a new out- look in this publication. Here is operational research in progress: in application. The concept and consummation of PARR reflect great credit on the veterinarians con- cerned, on the managers of Clover Park (J. Payne) and Hillgrove Station (R. Warden), and on Merck, Sharp and Dohme.

There is a foreword by Dr 1. L. Johnstone, Director of PARR, and brief prefaces from A. W. Lee, District Agricultural Economist, Department of Agriculture, Hamilton, and K. K. Cassidy, “Waverley Rise”, New- stead, Victoria. P. Brown, Farm Management Con- sultant, Wellington, New South Wales presents some independent comments on Clover Park.

The manager, Mr J. Payne, concludes with “On Clover Park, as on most other farms, new methods and approaches to management must be continually sought and implemented. The need for careful planning, strict budgeting and hard work remains critical and must be given due consideration, as all these factors will influ- ence the future viability of the enterprise. Whether Clover Park has the capacity to develop and improve its efficiency at a rate fast enough to offset the economic pressures of the future, will no doubt prove to be more than an interesting challenge.”
