Just as I was about to start I got the latest New Zealand Memories Magazine from the Thames Library. (Issue 138) There is a four page article "The Bella Street Pumphouse" by Bella Street Pumphouse Society.
The problems of groundwater and the impact it had on mining are discussed. Hence the "Hauraki Mining Company constructed the Thames Hauraki Pump House (now called the Bella Street Pumphouse) at the site of the Queen of Beauty Mine, in 1898." page 8

The poppet heads that were dotted around the town, were built over mine shafts and housed the mechanism to lower cages up and down the shaft - carrying miners to and fro, along with transporting ore to the surface.

Now at last to the photo that triggered the need for the post. The poppet head looks near completed, while the boilers are just arriving - the building of the pumphouse underway.

Poppet Head facts:
"The four legs of the poppet head were made of kauri. They were approximately 19.8m long measuring 76cm at the base and tapering to 45cm at the top. Each leg was set in sole pieces and were firmly embedded in concrete. The whole structure was firmly braced together. On top were two sheave wheels 2.7m in diameter. The whole structure was capable of bearing a transverse working strain of 400 tons."
