The Exhibits of the Department of Agriculture in the 
(Queensland International Exhibition at Bowen 
Park, 1897. 
Amonast the most interesting aud instructive exhibits at the International 
_ Exhibition must be classed those of the Queensland Agricultural Department, 
embracing as they do a great range of industries of importance to all classes of 
the community from the far North to the extreme South and West. 
The amount of space allotted to the Department enabled the authorities 
to display to the greatest advantage the various products of the colony, and the 
result has been that in no other section are such facilities given to the public 
to examine the exhibits with comfort and profit. Hyerything is distinctly 
labelled, so that a catalogue is scarcely needed by the visitor. 
Taking the various bays in order of numbers, we commence with Bays Nos. 
26 and 27 in which are displayed all the paraphernalia of the Queensland 
Travelling Dairy, consisting of a Steam Turbine Cream Separator, “ Sharple’s 
Russian,” with a capacity of 65 gallons; Cream Separator (steam 
turbine) “Laval,” capacity 95 gallons; ‘‘ Victoria’? Cream Separator, 
eapacity 35 gallons; Babcock Milk and Cream Tester, “ Sharple’s Russian”; 
“The Laval’? Pasteuriser, with a capacity of 400 gallons; and “The 
Laval” Cream and Milk Cooler with the same capacity. There are 
also two additional milk-coolers—“ Dobson’s Patent,” and ‘‘ Moore’s Patent.” 
The other portions of this very complete plant consist of a concussion churn, 
a butter-worker, cheese vat and plant complete, a salting and cooling sink, and 
cheese presses. The plant, under the supervision of Mr. J. Mahon, dairy 
expert, has been a prime factor in instructing dairymen in various parts of the 
colony in the latest improved methods of conducting this important and 
growing branch of agriculture. 
These bays, as well as all the others occupied by the Department, are well 
supplied with very magnificent crotons provided by Mr. L. Olsen, of Roek- 
hampton, and with palms, ferns, and other plants from the Brisbane Botani¢ 
Gardens. 
The following description of the Laval Pasteuriser and Cooler will doubt- 
less be of interest to dairymen and others :—

The introduction of pasteurisation in the dairying industry is one. of the 
latest developments of the day, and has already proved to maintain the same 
high value as regards the wholesomeness and increased keeping qualities of the 
products as it has done in the brewery and other industries where it has been 
applied. : 
Pasteurisation is not, as is generally believed, a method of preserving 
the milk to prolong its keeping qualities. Pasteurised milk will, however; 
keep longer than non-pasteurised; but the main object of the method is the
