No. 2 (1921) REMARKS ON CANNING 63 



such tube wells the water should be forced to a large masonry 

 tank fixed at such a height— not higher so as to save labour in 

 pumping — as will, allowing for friction in the pipes, supply every 

 part of the cannery with tap water. Plenty of pure water and its 

 continuous use is a necessity in a cannery. 



55. (2) A provision of solid hard-wood tables, etc. — Those in the 

 gutting room slope very slightly either to the edges or to the centre 

 where a small channel carries the washing water and offal into 

 buckets or drains. Since the knife is often used upon fish the 

 tables are wooden rather than stone and zinc covered. The tables 

 in the packing room may usefully be covered with zinc or may 

 have slate or tiled tops since spilt oil and fragments of fish soil 

 the tops. The solderers' tables are long narrow tables on which 

 the cans are placed for closing, the men sitting behind them with 

 their turn-tables. There should also be a variety of small tables 

 or racks for holding the wire baskets full of cans at the testing 

 and exhausting vats, etc. Wooden stools for the staff are also 

 necessary. 



In the observation room there should be one or two large tables, 

 and racks to hold at least one week's outturn. 



The store room should be entirely surrounded by wooden racks 

 with others in the middle space, and should accommodate at least 

 three months' output ; these should be arranged and labelled 

 according to the contents of the cans, so as to avoid confusion. If 

 by reason of heavy output the cans are piled on the floor arrange- 

 ments should be such that defective (leaky) tins may at once be 

 detected and removed lest the tainted fluids from such cans cause 

 unpleasantness and soil other cans. 



The issue room should have proper racks for storing the 

 labelled tins upon issue from store ; the labels themselves should 

 be neatly stored in packages in a convenient set of labelled 

 drawers, so as to prevent confusion and loss. The packing of 

 tins into cases for despatch is usually carried on in this room or 

 its verandahs. 



The fittings of the office need no description, while those of the 

 laboratory depend on the work to be done. 



Machines and Tools. 



56. In the gutting shed the chief tools required are sharp knives 

 and scissors, all of good steel, for which it is well to have a small
