Idaho History: Manufacturing in Boise area in the days before the car

Here's a link to today's ID Statesman article titled: "Necessity was the mother of invention in early Idaho". An excerpt reads: 

In 1890, the Idaho Statesman pointed out that "Boise is becoming quite a manufacturing center in the way of wagons, carriages and stage coaches, especially the latter. Several were shipped west yesterday from one of the largest factories. They are models of workmanship and strength."

In the horse-powered world of the 1890s, all kinds of manufacturing flourished that was related to horses. In 1892, Boise's newest industry was a factory for the manufacture of horse collars. The Statesman said the company had six employees but was expected to grow. "The Boise City Manufacturing Co. Ltd." advertised In the 1893 city directory that it was the manufacturer of horse collars of every description and that it operated its own large tannery for the manufacture of the leather it used in its products.
