Marine Department

The Department exhibits power-driven industrial machinery provided with a selected variety of the best-known devices for safeguarding accidents to operators, including fixed guards, push-away guards, interlocking guards, instantaneous stop devices and double- hand-control, also machines with guards incorporated into their design. Power is provided to enable the functions of the various guards to be demonstrated under working conditions.

Boilers, including a large model of a high-pressure water-tube boiler, pressure-vessels of various types, and models of cranes and components of lifting appliances, all illustrating good design and other safety features, are exhibited.

In addition to these mechanical safety measures, suitable safety equipment for wearing on the person is shown, such as goggles, safety gloves, safety overalls, etc.

A comprehensive display of attractive safety posters suitable for a works safety organisation is made.

Some interesting exhibits of failures of engineering materials have been collected for the display.

The Department also exhibits some of the appliances adopted for promoting safety of life at sea on merchant ships. A model bridge is installed and fitted with aids to navigation such as compasses, navigation lights, echo-sounder, direction-finder, range-finder, etc. Various items of life-saving equipment, including a model lifeboat, fire-fighting and extinguishing equipment and other safety features are shown. Safety in the design of fishing vessels is featured by a full-size diesel engine, complete with shafting and propel lor working in water. The engine-room is entered from the model bridge. There is a working model of a ship's cargo gear.

In addition to these, there are shown in operation certain types of lights exhibited in lighthouses on the coast, and a radio beacon and radio-telephone, as installed at certain of the lighthouse stations.

The Fisheries Section of the Department's exhibit shows the principal kinds of commercially-utilised fish found in New Zealand waters, together with fish of sporting interest, and the acclimatised game-fish which now comprise the more valuable part of our fresh-water fishery assets and have much enhanced the attractiveness of New Zealand rivers and lakes for both resident and visiting anglers. The species are exemplified by models in life colours, by mounted specimens, and by actual fish exhibited in a refrigerated showcase.

Shellfish of actual or potential commercial importance are also exhibited. By means of models and illustrations the principal fishing methods and gear employed for taking fish for supplying the markets are illustrated, together with the primitive but exceedingly-ingenious fishing implements formerly used by the Maoris.

The nature and productivity of the marine fisheries of New Zealand are indicated by various graphic representations.

The native fresh-water fish which, with the exception of two species of eels, are of comparatively small size, are exhibited in the living state in aquarium tanks, which are also used to show juvenile specimens of acclimatised species of salmon, trout and other introduced fish.

Associated with the acquarium is a working example of the equipment used in hatcheries for the artificial incubation and rearing of salmon and trout.
