laboratories, and fittings for incandescent and ordinary gas lamps are 

 provided through the building, so that it can be used also as an auxihary 

 to the electric light in the event of hght being required at any time when 

 the electric plant may not be running. 



An ample supply of water for all purposes in the stables and 

 laboratories is drawn from a borehole situated about 200 yards to the 

 east of the main building. A Rees Roturbo high efficiency pump is 

 installed in the pump house. This is driven by a 5 horse-power vertical motor 

 direct coupled to the pump spindle, and is capable of delivering about 

 3,000 gallons per hour when running at a speed of 2,500 revolutions per 

 muiute. The water pumped from the borehole is delivered to a tank 

 situated near the gasometer, this tank being raised to a height of 40 ft. 

 above ground level in order to produce sufficient pressure for the water 

 to reach the taps in the upstairs rooms of the laboratory. The tank has 

 a capacity of 30,000 gallons which suffices for a two days' supply. A 

 system of mains distributes the water to the various laboratories, stables, 

 and the dwelling-houses where the staff reside. 



The whole of the above-mentioned plant is under the charge of an 

 electrician resident on the spot, an assistant being employed to run the 

 engine for lighting purposes at night. 



In every way most complete both in buildings and all accessories and 

 fitted up with the best and most modern equipment, the new Laboratories 

 have a wide field of work before them in research into the many and 

 hitherto little studied tropical and sub-tropical diseases of live stock of 

 South Africa.
