Chains and a photo from 1937.

cus­tom­ar­ily one chain wide.

Tra­di­tion­ally the Queen’s Chain is a strip of pub­lic-ac­cess land along coasts and wa­ter­ways, of up to 20 me­tres wide. The strip of land was orig­i­nally one chain (66 feet) wide.

The chain mea­sure­ment also sur­vives as the length of a cricket pitch, be­ing the dis­tance be­tween the stumps.

A job as a chain­man nowa­days falls un­der the broader ca­reer cat­e­gory of sur­vey­ing tech­ni­cians.

An­other trea­sure that Te Aroha Mu­seum has is a photo of a group of peo­ple at the trig on the top of Te Aroha.

A tri­an­gu­la­tion sta­tion, also known as a tri­an­gu­la­tion pil­lar, trigono­met­ri­cal sta­tion, trigono­met­ri­cal point, trig sta­tion, trig bea­con, or trig point, and some­times in­for­mally as a trig, is a fixed sur­vey­ing sta­tion, used in ge­o­detic sur­vey­ing and other sur­vey­ing projects in its vicin­ity.

By us­ing known dis­tances along the ground and an­gles it can be cal­cu­lated how far a given point is from the top of the trig.

The phys­i­cal com­po­nent of New Zealand’s ge­o­detic sys­tem is a net­work of con­trol marks that serve as phys­i­cal ref­er­ence points.

A num­ber of these marks are black and white trig bea­cons, seen on the tops of hills, or steel pins set into con­crete in ur­ban ar­eas.

These marks are used by sur­vey­ors to de­ter­mine the lo­ca­tion of property bound­aries in re­la­tion to the of­fi­cial ge­o­detic da­tum.

The photo, taken back in 1937 ac­cord­ing to mu­seum records, shows a group of tram­pers by the trig at the top of Te Aroha.

Does any­one know who these peo­ple might be?

Any in­for­ma­tion would be greatly ap­pre­ci­ated.

Te Aroha Mu­seum’s open­ing hours af­ter Labour week­end will be from 11am to 4pm daily.


Sur­veyor’s chain mea­sure on dis­play at Te Aroha Mu­seum. Does any­one know who the peo­ple in this photo taken in 1937 are?
