- Wisconsin Central Bridge Ruins, Somerset, WI (johnweeks.com)
The Wisconsin Central bridge over the Saint Croix river was built in 1884 by the Union Bridge & Iron Works. The Wisconsin Central was pushing west, and this bridge was the last link to connect Milwaukee and Chicago to Saint Paul. The bridge features a number of very well crafted cut-stone piers. There were nine 160-foot deck truss spans, one 160-foot pin-connected though truss span, and 25 plate girder spans, each 30-feet long.
- Tin (Wikipedia)
Tin is a chemical element with the symbol Sn (from Latin stannum) and atomic number 50. A silvery-coloured metal, tin is soft enough to be cut with little force, and a bar of tin can be bent by hand with little effort. When bent, the so-called “tin cry” can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, zinc, and mercury in its solid state.
